Weatherford has developed the reports and diagrams in this manual in order to give detailed information as to howWeatherford’s equipment either meets or exceeds the customer’s requirements.

The sections of this binder include the following guidelines:

General comments on float equipment Dimension Data and/or Drawings of Float Equipment Operational Procedures Ratings of Float Equipment Test Reports on Flow Endurance and Pressure Testing Drillout procedures and Reports Miscellaneous – a catch-all location for materials of importance

Weatherford’s float equipment is rated as one of, if not the best quality equipment in the world. Many large cementingcompanies, drilling contractors, and operators rely on Weatherford to supply their needs today and to develop theequipment of the future.

The standard Sure Seal 3 float equipment ratings are given on the enclosed tables along with a complete listing of themany tests we have performed over the past years.

Our engineering reports show how Weatherford derived its ratings on the float equipment and stage tool product lines.We have spent many hours researching these factors and how they are interrelated.

Weatherford has spent many years in developing the current product line and continues to produce the finest equipmentthrough a dynamic and growing Quality Assurance Program. Investment in the Research and Development Programs atWeatherford has increased over the past years and shall continue as we lead the industry in tool development.

Innovations such as the Sure Seal 3 valve system, Model 754HO Stage Tool, and the world’s leading Non -weldCentralizer are just a few of the contributions that Weatherford has brought to the Primary Cementing market place.

PRIMARY FUNCTION OF FLOAT EQUIPMENT

The following are the primary functions of our equipment:

Guide casing string to total depth.

Act as a one-way check valve while running casing to prevent contaminated mud from entering the casing. During themud circulation period, the valves must withstand the abrasive wear of the mud and cement.

Serve as a landing point for the various plugs (i.e., bottom plugs, top plugs) that are sent down the casing to separatethe fluids, and wipe the pipe clean between fluids. This is especially true for non-rotating plug systems.

Prevent the heavier cement in the annulus from “U-tubing” back into the casing, upon completion of the displacementprocess. This is its back pressure phase. The float collar serves as a back-up valve should the shoe valve fail.

Behave as a wall or seat to the bump pressure of the plug, after landing the tip plug the float collar. At this point someoperators go ahead and test the casing for burst and leaks before the cement hardens.

Withstand heat and pressure during the cement curing process.

FLOAT EQUIPMENT PRESSURE RATINGS

Float equipment must withstand very extreme conditions and has been referred to by some customers as a “casingblowout preventor.” Three primary forces that float equipment must withstand are:

1. Back Pressure2. Bump Pressure3. Tensile Force

Three secondary factors are:4. Temperature stability5. Chemical Resistance (H2S)6. Abrasion Resistance

BACK PRESSURE RATING FACTORS

The primary factors in the rating of float equipment are its ability to withstand “BACK PRESSURE” and its ability to keepthe hydrostatic head of the cement column contained in the annulus. Other factors effecting back pressure include:

1. Valve component strength2. Concrete flexural & shear strength3. Shell groove type and pattern4. Temperature stability5. Abrasion resistance of Seals

ABRASION TESTING OF FLOAT COLLARS

Weatherford’s test programs have determined the effects of abrasion on our valve systems; the results led to thedevelopment of the Sure Seal 3 valve system.

PDC DRILLABILITY OF VALVES

Weatherford’s Sure-Seal 3 float equipment incorporates a PDC drillable, spring-loaded phenolic plunger valve.Information on configuration and composition of other valve types is available on request.

6. Points Worth Noting on Float Equipment Orders

a. Make sure that there are no restrictions in previous casings of less than 1.3” over pipe size to be run. (Rule othumb, OD of float equipment is no larger than casing couplings.)

b. Unless the weight is specified, you will be sending out the equipment by “weight range.” The equipment built isgenerally the lowest weight in the range to give maximum ID or the least restriction when drilling out.

c. Grades of steel, if not specified, will be K-55, which is “suitable for use with N-80.” Other primary grades usedinclude L-80 and P-110.

d. Weatherford float equipment has been tested according to industry accepted standards for years. Since API hasput forth the “API Recommended Practice 10F,” the equipment will be rated by this new standard. There are no“standards” by API regarding float equipment, only a recommended practice for the testing of float equipment.

e. On stab-in float equipment jobs, the following information is required:

1) Lower connection for drill pipe – usually 4 ½” I.F.

2) Size of drill pipe used – for centralizer and stop collar (not same as connection).

3) Bowl and slips required? Slips will have inserts for Drill Pipe.

4) Base Plate – to fit on top of casing for bowl and slips.

5) Service Technician – always recommend the use of a Service Technician.

6) Pack-Off Head – use a pressure regulator to prevent accidental casing collapse.

A. GENERAL GUIDELINES AND FEATURES OF SHOES ANDCOLLARS

Weatherford-Gemoco’s casing guide, float, differential, Duplex, and Stab-In cementing equipment have been engineeredand manufactured to withstand the high pressures and temperatures encountered during cementing operations.Weatherford-Gemoco has improved the interchangeability of a given product by grouping the different weights of aparticular casing size through the use of weight ranging, grade selections, and thread type.

Weight ranging is a method by which a product of a given casing size is grouped by its dimensional and/or pressureproperties with the assurance that after drill out, the case (shell) will drift the lightest weight stated and meet the pressureperformance (API Specification 5CT) of the heaviest weight stated. This allows a single product to cover multiple weights

of a given size of casing. Weight ranging allows our customers to minimize on hand inventory, therefore, reducing theirout of pocket expense. Weight ranging mainly occurs on API 8rd threads, API Buttress threads, and slip jointconnections.

Shoes are weight ranged, starting at the lightest weight and going to the heaviest weight for a given size of casing. Thislarge weight range works due to the fact that the shoe case material does not encounter differential pressures once theshoe has been drilled out. The shoe will have an inside diameter which will allow the drift of the lightest weight to passand an outside diameter within the tolerances of the outside diameter of the appropriate coupling or box thread on theproduct.

Collars are similarly weight ranged, but there must be sufficient wall thickness of a given material to provide the pressureperformance of the desired casing size, weight and grade.

GRADE SELECTIONS:

Weatherford-Gemoco offers a Std. (standard) grade of product of shoes and a Std. grade plus a P.G. (premium) grade forcollars. Std. shoe equipment is H2S resistant and suitable for use with all casing grades. Std. collar equipment is H2Sresistant and suitable for use with API Grades L-80/N-80 & lesser, including any similar proprietary grade of steel. P.G.(Premium Grade) shoes and collars are made of high strength steel meeting or exceeding P-110 specifications.

When it is necessary for a shoe or collar to meet the exact chemical and physical properties of a special grade of steel,such as L-80 or C-90, then it is necessary to special order.

THREAD TYPES:

Std. and P.G. equipment is available with API 8-round LTC, STC, or buttress (BTC) connections.

* Size 4-1/2" through 9-5/8" Std. 8-round equipment is furnished with LTC box and STC pin.* Size 4-1/2" through 9-5/8" P.G. 8-round equipment is furnished with LTC box and pin.* Size 10-3/4" through 20" Std. & P.G. 8-round equipment is furnished with STC box and pin.

SPECIAL ORDERS:Weatherford-Gemoco, at the customer’s request, will design and manufacture equipment to meet special requirementssuch as corrosion resistant materials, premium thread connections, non-API casing sizes and/or weights, etc.

AUTO-FILL BIT SAVER OPERATIONAL PROCEDUREDuring the running of the Automatic Fill Equipment the following points should be addressed:

1. Inspect the shoe and collar to ensure the wedges are all still in place (If any have become dislodged refer to valveredress instructions).

2. On running the auto-fill equipment into the well the mud level inside the casing should be seen to rise fairly quickly asan indication the equipment is operating correctly.

3. Periodically throughout a job, the casing fluid level should be checked visually to ensure the valve is operatingcorrectly. The driller will also be able to monitor the hookload and fluid returns as a guide to the equipment operation.

4. Run the casing joints at a reasonable speed; avoid harsh acceleration or deceleration which can produce fluidmomentum flow rates which can prematurely trip the valve (see notes of premature tripping).

5. Should it be necessary to circulate during the casing running operations this is acceptable to do provided thecirculation rate is kept at least 20% below the minimum trip rate of the particular wedges i.e., for 11-14 B.P.M.circulation should not exceed 6-7 B.P.M. or the valve could trip prematurely.

6. When the shoe has reached the predetermined depth to be tripped (or well conditions have deteriorated sufficiently torequire the valve to be tripped, the procedure is:

a. Install circulating head/cementing head and rig up lines

b. Start circulation and monitor for full returns.

c. Increase circulation to maximum conversion rate and circulate for approximately a minute. Note: there is nosurface indication of valve tripping.

7. With these circulation rates the valve should trip easily. Some operators, however, prefer to trip the equipment one joint off the bottom and to run in the hole with the last joint. This ensures valve closure and a steady mud level.

8. When the valve has been tripped, it will function as a conventional float valve and will allow fluid to pass through thestring into the well but not in the reverse direction. If the casing string was tripped off-bottom, the casing will have tobe filled from the surface for the remainder of the run.

9. When the casing has been run to the bottom, the primary cementation job should then be carried out in the “normalmanner.”

WEDGE DETAILS:

Flanged Wedge – Three sizes of flanged wedges are used for:

9-10 B.P.M.6-8 B.P.M. Standard Wedge – the standard wedge is used for 11-14 B.P.M. conversion flowrate.

3-5 B.P.M. conversion flowrates

The wider flange area creates a larger flow impact area which requires a lower flowrate to dislodge the wedge. The basicdifference between 9-10 B.P.M., and 3-5 B.P.M., is the size of the flange.

PREVENTING PREMATURE CONVERSION:

IT IS IMPORTANT THAT THE DRILLER IS AWARE THAT RAPID STOPPING OF THE CASING MOVEMENT CANLEAD TO PREMATURE VALVE TRIPPING.

RUNNING THE CASING JOINTS AT A REASONABLE SPEED IN THE WELL AND ALLOWING THE AUTOMATIC FILLEQUIPMENT TO OPERATE CORRECTLY SHOULD PRODUCE TIME SAVINGS AND LEAD TO A SMOOTHERCASING RUNNING OPERATION.

If there is a possibility of lost circulation the trip rate need only be held for a short period.

NOTE: THERE IS NO SURFACE INDICATION THAT THE VALVE HAS TRIPPED.

The wedges are sized so that the wedges from the float collar will pass through the float shoe during circulation.

When circulation is stopped, after the valve has been tripped, the plunger will move fully up to close the valve.

In this position the valve operates as a conventional valve allowing the fluid to pass through the string but it will preventflow from the well into the casing string.

IMPORTANT

Since the valve will trip at the rates detailed (according to the type of wedges installed) it is important that fluid movementin the casing, while the casing is being run, does not prematurely trip the valve.

Premature tripping is caused by a surge of fluid being forced through the valve if the casing’s downward motion isstopped. This can happen if the casing hangs up on a ledge or is set in the slips too rapidly.

This flow, caused by the fluids momentum, can be significant. The table shows the approximate fluid flow rates generatedat different casing running speeds (assuming the casing movement is stopped instantaneously).

TRIPPING THE AUTOMATIC FILL EQUIPMENT

At the depth specified by the operator the Automatic Fill equipment should be “tripped” (i.e., the wedges flushed out andthe valve allowed to close and operate as a conventional-fill valve allowing fluid to pass down the string only.)

The further the casing string is run with the valve held open the greater the time saved. However, the operating companywill determine the tripping depth based on:

Presence of hydrocarbons. Possible overflow due to mud imbalance Hole conditions when running casing Amount of cuttings suspended in drilling fluid Potential time savings Formation sensitivity to range pressures

The valve is tripped by circulation of fluid as shown.

Circulation should be established and the rate increased to the maximum rate for the wedges fitted.

Wedges are available to provide one of four trip rate ranges. The trip rate ranges normally selected for each casing sizeare indicated below:

Casing Size Valve Trip Rate (BPM)20”, 18 5/8”, 16”, 13 3/8” 11-14

9 5/8” 9-107” 6-8 or 3-5

As variation in the mud weight and viscosity can affect the valve trip rate it is desirable to circulate 10-20% above themaximum rate for a short period (1-2 minutes).

The fluid flow will move the plunger downwards, compress the spring and allow the wedges to be circulated out throughthe bottom of the valve.

REDRESSING THE AUTOMATIC-FILL VALVE

In general Automatic Fill Float Equipment will be shipped with appropriate wedges to the rig site.

If the original wedges become dislodged during transit it may be necessary to install replacement wedges at the rig site.

Re-dressing is straightforward if the float equipment is not attached to a casing joint. The following procedure should befollowed if the equipment is on a casing joint pin end.

Re-dress is not possible if the float equipment is attached to the box end.

1. Bend two welding rods to form small hooks at one end.

2. Insert the rods into the bottom of the valve and hook the top of the spring.

3. Pulling back the rods will compress the spring and pull the plunger to the bottom of the valve exposing the wedgegroove.

4. While holding the rods, the plunger can be pulled down easily and the wedges can now be inserted.(NOTE: The wedges should be given a light coating of pipe dope to make installation easier.)

5. The spring should then be released gently and the wedges will slip back into place correctly.

6. Unhook and remove the welding rods.

If the float equipment is not made up on to a casing joint it may be easier to push down the plunger from above and inserthe wedges from beneath.

OPERATING INSTRUCTIONS FOR MODEL 307 & 407 AUTO-FILL

FLOAT EQUIPMENT A Model 407 cemented flapper float collar with auto-fill tube should be run only with a guide shoe below having a 2.2” orlarger ID. Model 202 guide shoes meet this requirement. NOTE: A Model 307 float shoe should not be run below aModel 407 float collar.

Model 307 or 407 float equipment should not be run when a surface pressure indication of conversion is required at thesurface, or when a high conversion pressure could have adverse effects (such as when running inflatable packers,hydraulic opening stage tools, or hydraulic set liner hangers.

Model 1306 and 1406 auto-fill float equipment should be run when an auto-fill tube type flapper float shoe and collar arerun in tandem. Model 355 and 455 fill-up flapper float equipment is also available for critical wells when only the trippingball is allowed to flow down to equipment below.

Before running Model 307 or 407 float equipment, place the ball above the AFU tube and hammer the tube down to insurethat excessive force is not required to move the tube down. This will also serve to remove corrosion, which could affectthe pressure required to pump out the AFU tube. If more than 5 strikes with a 4lb hammer are required to move the tubeout of the valve throat, continue to move the tube up and down until it can be removed with 5 strikes or less. Return the AFU tube to its original position after completing the test.

Make-up float shoe or float collar onto casing string. Apply Weatherford Tube LokTM

compound to the lower six shoe jointthread connections (pin end only) to prevent the shoe joints from backing off during drillout.

It is important to monitor the filling of the casing. Automatic fill equipment is highly susceptible to plugging from solids andcuttings suspended in the mud entering the casing from the annulus. Observation of fill can be accomplished by one oftwo methods. One is by watching the weight indicator and graph to insure that you are continually picking up weight and

not decreasing or losing weight. The other is by taking a wet rag and placing it over the top of the casing. The air beingdisplaced out of the casing will blow a parachute effect on the rag.

The Fill-up Flapper valve has a 1 1/2" diameter (1.77 in2) flow area through which the casing fills. If the casing stops

filling, simply rig up a swage and break circulation. Keep flow rate as low as possible to avoid pumping out the auto-filltube (< 3BBL/min). Displace the capacity of the casing, then go back to running the casing. If overfilling of the casingoccurs, pump heavier mud into the casing to counteract the imbalance. Once the casing is landed, rig up the swage orcementing head and establish circulation.

Dropping the 1 3/4" drop ball before circulation is established is not recommended because the cuttings and drill solidsthat accumulate on top of both the fill-up shoe and collar act as a bridge with the ball further complicating matters. Oncecirculation is broken the 1 3/4" O.D. drop ball can be released and cementing plugs loaded. The weighted ball is thencirculated down to the fill-up collar and/or shoe, converting them to hold back pressure. An increase of 100-1000 psi maybe noted as the drop ball passes through and converts the fill-up equipment to hold back pressure.

Be aware that 8 5/8" and larger equipment run in a deviated hole may not allow the weighted drop ball into the fill-upassembly to convert the equipment to hold back pressure. Sizes 8 5/8" to 10 3/4" run in a 25° or greater hole deviationand size 13 3/8" run in a 20° or greater hole deviation should be noted and other equipment provided to do the job.

REGULAR STAB-IN CEMENTING OPERATING PROCEDURES

EQUIPMENT REQUIREMENTS

Stab-In Float Shoe or Collar Model 154 Stab-In Stinger to match 3.5” I.D. receptacle Centralizer(s) to fit drill pipe O.D. and casing I.D. Running tools –false rotary plate, bowl & slips for drill pipe Top-out connection (crossover from cementing lines to drill pipe)

PRELIMINARY INSPECTION

Inspect float equipment for damage and verify that size, thread, weight, and grade match casing being run. Verify thatreceptacle is clean and has 3.5” diameter smooth bore for stab-in adapter.

Thread Stab-In Stinger onto drill pipe hand-tight to insure threads match drill pipe being run, then remove. Measure O.D.of stinger to insure fit within 3.5” I.D. r eceptacle.

Inspect drill pipe centralizer(s), stop collar(s), false rotary plate, bowl and slips to verify that they are in good condition andsuitable for use with drill pipe and casing to be run.

Verify that top-out connection contains no foreign objects and that the thread or crossover matches drill pipe.

PROCEDURE

1. While running casing, install Stab-In Float Collar or Shoe at desired location in casing string and run to setting depth.

It is recommended that Weatherford Tube Lok be applied to the threads of the float equipment and the first 4 to 6 joints of casing to prevent unthreading during drillout. Fill the casing from the surface to keep casing from floating and

to prevent excessive collapse pressures from acting on the casing.

2. Land casing as close to rig floor as possible. Rig up to run drill pipe.NOTE: Large diameter casing strings may need to be tied down if a low-density displacement fluid is used to displacea high-density cement column, causing the casing to float.

3. Pick-up first stand of drill pipe to run in hole. Install drill pipe stop collar 3 to 4 feet above tool joint.

4. Screw Stab-In Stinger to bottom of drill pipe and torque connection to at least 2000 ft-lbs torque. Dope Stab-InStinger nose and O-rings liberally.

5. Place centralizer around stop collar on drill pipe.NOTE: If hole is deviated more than 5 deg. or dogleg is present adjacent to Stab-In Float Collar or Shoe, more thanone centralizer may be recommended to guide stinger into receptacle. Consult Weatherford Gemoco engineeringpersonnel for recommended centralizer spacing in these situations.

8. Make up Top-out connection to the drill pipe landing joint.

9. Fill volume between casing and drill pipe with mud. Break circulation through drill pipe.NOTE: The mud level between the drill pipe and the casing may rise slightly due to expansion of the drill pipe. If themud level continues to rise, the stinger may not be stabbed into the receptacle. In this case, stop circulation, pick upstinger off of float equipment, and re-stab stinger into receptacle. Rotating drill pipe while stabbing-in will help stingerenter receptacle if off-center.

10. After circulation and conditioning of hole is complete, rig up cementing lines and pump cement.

11. Displace cement with calculated amount of displacement fluid to remove all cement from drill pipe. Cement can beover displaced if a stab-in collar is used with one or more joints below. If a stab-in shoe is used, cement should beunder displaced. Excess cement can be washed out after checking floats and pulling stinger out of receptacle.NOTE: Be careful while displacing not to exceed pressure required to overcome weight holding stinger in receptacle.

Maximum allowable displacement pressure (in psi) = weight (in lbs) of drill pipe slacked off onto stinger divided by9.62 sq. in.

12. Check to determine if float equipment is holding by releasing pressure and observing volume of flow-back, allowing foraeration. If excessive flow-back without loss in pressure is observed, pump calculated displacement and check floatequipment again.

13. With float equipment holding and flow-back stopped, pull drill pipe out of hole.

14. Remove Stab-In Stinger, centralizer(s), and stop collar(s) from drill pipe.

WEATHERFORD GEMOCO DOUBLE FLAPPER DIFFERENTIAL FILL

(DF2

) EQUIPMENT:Operating Instructions for Model 343 and 443 Differential Fill-Up Equipment Circulating Type with 1-3/4” Drop Bal

It is important to monitor the filling of the casing. The reason is that fill-up equipment is highly susceptible of beingplugged due to the solids and cuttings suspended in the mud entering the casing from the annulus. Observation of fill canbe accomplished by one of two methods. One is watching the weight indicator and graph making sure that you arecontinually picking up weight and not decreasing or losing weight. The other is by taking a wet rag and placing it over thetop of the casing. The air being displaced out of the casing will blow a parachute effect on the rag.

If the equipment becomes plugged, simply rig up a swage and break circulation. Displace the capacity of the casing, thengo back to running the casing. Once the casing is landed, rig up the swage or plug container and establish circulation.

Dropping the ball before circulation is established is not recommended because the cuttings and drill solids thataccumulate on top of both the fill-up shoe and collar act as a bridge with the ball further complicating maters. Oncecirculation is broken the 1-3/4” O.D. drop ball can be released and plug container loaded. The weighted ball is thencirculated down to the differential fill-up collar and/or shoe, converting them to hold back pressure. An increase of 600-800 psi will be noted as the drop ball passes through and converts the differential fill-up equipment.

Note that only one weighted drop ball is needed to convert two or more pieces of equipment. Be aware that 8-5/8” andlarger equipment run in a deviated hole may not allow the weighted drop ball into the fill-up assembly to convert the

equipment to hold back pressure. Sizes 8-5/8” to 10-3/4” run in a 25 or greater hole deviation and size 13-3/8” run in a

20 or greater hole deviation should be noted and other equipment provided to do the job.

If any type of other equipment is involved, confirm that the drop ball will pass through it, example: such as a guide shoeorifice.

Weatherford-Gemoco’s Packoff Float shoe is designedto protect the formation below the shoe from cementcontamination. The packoff float shoe’s elementexpands to seal the annulus between the casing and

well bore.

An aluminum flapper valve allows flow downward andholds back pressure before and after the packer is set.

Upon running the shoe into the hole, fluid can becirculated out the bottom of the shoe without setting thepacker until the tripping ball is dropped. To set thepacker a tripping ball (1-1/2” dia.) is dropped into thecasing and allowed to fall to the flapper on top of theshoe. The ball is then pumped through the flapper andseated upon the sliding sleeve. Pump pressure is thenapplied which moves the sliding sleeve down and

compresses the packer element. As the element iscompressed against the well bore, pump pressure buildsto approximately 1000 psi which shears the screwsholding the sliding sleeve. The sleeve is then pumpeddown exposing four ¾” wide slots which allow fluid flowinto the annulus above the packing element. Theelement is held in position by a ratchet ring, which doesnot allow any reverse movement.

The casing can be cemented through the side portsabove the packing element. Upon completion ofcementing, the flapper valve holds back pressure.

Make up float shoe and/or float collar onto casing string. Apply Weatherford Tube Lok compound to the lower six shoe joint thread connections (pin end only) to prevent the shoe joints from backing off during drillout.

It is important to monitor the filling of the casing. Automatic fill equipment is highly susceptible to plugging from solids and

cuttings suspended in the mud entering the casing from the annulus. Observation of fill can be accomplished by one oftwo methods. One is by watching the weight indicator and graph to insure that you are continually picking up weight andnot decreasing or losing weight. The other is by taking a wet rag and placing it over the top of the casing. The air beingdisplaced out of the casing will blow a parachute effect on the rag.

The Fill-up Flapper valve has a 1-1/2” diameter (1.67 in2) flow area through which the casing fills. If the casing stops

filling, simply rig up a swage and break circulation. Displace the capacity of the casing, then go back to running thecasing. If overfilling of the casing occurs, pump heavier mud into the casing to counteract the imbalance. Once thecasing is landed, rig up the swage or cementing head and establish circulation.

Dropping the ball before circulation is established is not recommended because the cuttings and drill solids thataccumulate on top of both the fill-up shoe and collar act as a bridge with the ball further complicating matters. Oncecirculation is broken the 1-1/2” O.D. drop ball can be released and cementing plugs loaded. The weighted ball is then

circulated down to the fill-up collar and/or shoe, converting them to hold back pressure. An increase of 600-800 psi will benoted as the drop ball passes through and converts the fill-up equipment to hold back pressure.



20 or greater hole deviation should be noted and other equipment provided to do the job. For Model 455NS Float Collars

(with Wiperlok Landing Plate) the maximum recommended deviation at the valve is 10 for 7 5/8” and larger sizes.

If any other type of equipment (such as a float shoe or liner hanger) is involved, confirm that the drop ball will passthrough it.

It is important to monitor the filling of the casing. Observation of filling can be accomplished by one of two methods. Oneis by watching the weight indicator and graph to insure that you are continually picking up weight and not decreasing orlosing weight. The other is by taking a wet rag and placing it over the top of the casing. The air being displaced out ofthe casing will blow a parachute effect on the rag.

Automatic fill equipment is susceptible to plugging from solids and cuttings suspended in the mud entering the casing fromthe annulus. The Fill-up Flapper valve normally has a 1-1/2” diameter (1.72in

2) flow area through which the casing fills.

However, with the ball pinned in place (Model 467 and 457) this flow area is somewhat restricted reducing it to 1.52 in2. If

the casing stops filling it is recommended that the equipment be converted by breaking circulation. Since the ball isalready in position to convert the float collar an increase of 600-1000 psi will be noted immediately as the ball passes

through the valve and releases the flapper to hold backpressure. Of course auto-filling will not be possible from this pointon so a means of back filling the casing will have to be employed. The Model 456 collar utilizes a design that eliminatesthe need to drop the ball from surface in highly deviated wells, while eliminating the pin used in the model 467 and 457.The model 456 design does not reduce flow area during run-in.

If the ball is pinned in place, do not drop the extra ball provided with the shoe. Only one ball is needed to convert two ormore pieces of equipment. Be aware that 8-5/8” and larger equipment run in a deviated hole may not allow the weightedball to drop into the lower shoe to convert the valve for backpressure. It is recommended that a high angle guide beprovided on the auto fill float shoe for sizes 8-5/8” to 10-3/4” run in 25

o or greater hole deviation and 13-3/8” size run in 20

o

or greater hole deviation.

Note: The Model 457 can be converted to circulating type auto fill by unscrewing the ball retainer with left hand rotationwith the plastic tool provided, then removing both the retainer and the 1-1/2" diameter drop ball. In this case, the 1-1/2"drop ball is released from the surface after establishing circulation. The Model 467 may also be converted to a circulating

type auto fill, prior to running, by breaking the retaining pin and then removing both the pin and the 1-1/2” diameter dropball. In this case, the 1-1/2" drop ball is released from the surface after establishing circulation (Only equipment with ballguides are candidates for this conversion). All fill-up flapper models may be converted to a standard check valve prior torunning, by driving the ball through the valve, releasing the flapper. Caution: When converting a model 467, special careshould be given to the finial condition of the sheared retaining pin that remains inside the valve throat. Due to its closeproximity to the flapper seat, it is possible that a small piece of the pin may prevent the flapper from closing properly. Anyremaining part of the pin that protrudes in the direction of the flapper seat should be removed.

It is important to monitor the filling of the casing. Observation of filling can be accomplished by one of two methods. Oneis by watching the weight indicator and graph to insure that you are continually picking up weight and not decreasing orlosing weight. The other is by taking a wet rag and placing it over the top of the casing. The air being displaced out ofthe casing will blow a parachute effect on the rag.

Automatic fill equipment is susceptible to plugging from solids and cuttings suspended in the mud entering the casing fromthe annulus. The Fill-up Flapper valve normally has a 1-3/4” diameter (2.22 in

2) flow area through which the casing fills.

However, with the ball pinned in place this flow area is somewhat restricted reducing it to 1.52 in2. If the casing stops

filling it is recommended that the equipment be converted by breaking circulation. Since the ball is already in position toconvert the float collar an increase of 600-1000 psi will be noted immediately as the ball passes through the valve and

releases the flapper to hold back pressure. Of course auto-filling will not be possible from this point on so a means ofback filling the casing will have to be employed. The Model 456 collar utilizes a design that eliminates the need to dropthe ball from surface in highly deviated wells, while eliminating the pin used in the model 467 and 457. The model 456design does not reduce flow area during run-in. Flow area for model 456 is 2.22 in

2.

If the ball is pinned in place, do not drop the extra ball provided with the shoe. Only one ball is needed to convert two ormore pieces of equipment. Be aware that 8-5/8” and larger equipment run in a deviated hole may not allo w the weightedball into the lower shoe to convert the valve for back pressure. It is recommended that a high angle guide be provided onthe auto fill float shoe for sizes 8-5/8” to 10-3/4” run in 25

o or greater hole deviation and 13-3/8” size run in 20

o or greater

hole deviation.

Note: The Model 457 can be converted to circulating type auto fill by unscrewing the ball retainer with left hand rotationwith the plastic tool provided, then removing both the retainer and the 1 3/4" diameter drop ball. In this case, the 1 3/4"drop ball is released from the surface after establishing circulation. The Model 467 may also be converted to a circulating

type auto fill, prior to running, by breaking the retaining pin and then removing both the pin and the 1 3/4" diameter dropball. In this case, the 1 3/4" drop ball is released from the surface after establishing circulation (Only equipment with ballguides are candidates for this conversion). All fill-up flapper models may be converted to a standard check valve prior torunning, by driving the ball through the valve, releasing the flapper. Caution: When converting a model 467, special careshould be given to the final condition of the sheared retaining pin that remains inside the valve throat. Due to its closeproximity to the flapper seat, it is possible that a small piece of the pin may prevent the flapper from closing properly. Anyremaining part of the pin that protrudes in the direction of the flapper seat should be removed.

Make up float shoe and/or float collar onto casing string. Apply Weatherford Tube Lok compound to the lower six shoe

joint thread connections (pin end only) to prevent the shoe joints from backing off during drillout.

It is important to monitor the filling of the casing. Automatic fill equipment is highly susceptible to plugging from solids andcuttings suspended in the mud entering the casing from the annulus. Observation of fill can be accomplished by one otwo methods. One is by watching the weight indicator and graph to insure that you are continually picking up weight andnot decreasing or losing weight. The other is by taking a wet rag and placing it over the top of the casing. The air beingdisplaced out of the casing will blow a parachute effect on the rag.

The Fill-up Flapper valve has a 2” diameter (3.1 in2) flow area through which the casing fills. If the casing stops filling

simply rig up a swage and break circulation. Displace the capacity of the casing, then go back to running the casing. Ifoverfilling of the casing occurs, pump heavier mud into the casing to counteract the imbalance. Once the casing islanded, rig up the swage or cementing head and establish circulation.

Dropping the ball before established circulation is not recommended because the cuttings and drill solids that accumulateon top of both the fill-up shoe and collar act as a bridge with the ball further complicating matters. Once circulation isbroken the 2” O.D. drop ball can be released and cementing plugs loaded. The weighted ball is then circulated down tothe fill-up collar and/or shoe, converting them to hold back pressure. An increase of 600-800 psi will be noted as the dropball passes through and converts the fill-up equipment to hold back pressure.



20 or greater hole deviation should be noted and other equipment provided to do the job. For Model 455NB Float Collars

(with Wiperlok Landing Plate) the maximum recommended deviation at the valve is 10 for 7 5/8” and larger sizes.

If any other type of equipment (such as a float shoe or liner hanger) is involved, confirm that the drop ball will pass

through it.

WEATHERFORD COUPLING INSERT FLOAT VALVESINSTALLATION AND OPERATING INSTRUCTIONS

INSTALLATION OF MODEL 1111 AND 1112 INSERT FLOAT VALVES :

The Model 1111 is the conventional Insert Float Valve. This model can be run with other types of conventional floatequipment. The Insert Float Valve with Auto-Fill Tube (Model 1112) may not be compatible with other types of floatequipment positioned lower in the casing string. It should only be run above a Guide Shoe, a Model 1306 Auto-Fill Shoe,or a Model 1406 Auto-Fill Collar.

The Model 1111 can become the Model 1112 and vise versa with the addition or removal of the AFU kit.

With either model, proper installation is essential for an effective seal. First, clean the casing coupling thoroughly withsolvent or other cleaners to remove all thread coatings. Place a fresh, thin coat of pipe dope or Weatherford Tube- Lok™

on the coupling threads. Screw in the Insert until it is made up tight in the coupling using the installation bolts furnished(Remove bolts after installation). The standoff from the valve's outermost face to the face of the coupling should begreater than or equal to the length of a pin connection minus three threads. Note: If the Insert does not achieve its properposition in the coupling, it is possible for the field connection face to contact the Insert and possibly shear the threadsduring tong makeup. This could destroy the back pressure holding capability around the circumference of the InsertValve.

OPERATION OF THE MODEL 1111 INSERT FLOAT VALVE:

The flapper of the Model 1111 Insert Float Valve acts as a check valve, which allows flow downward but checks upwardflow while running casing and cementing.

OPERATION OF THE MODEL 1112 INSERT FLOAT VALVE W/ AUTO-FILL TUBE:

Upon running the casing to T.D., break circulation, drop the included weighted drop ball, circulate the ball down to theinsert float valve, pressure up to 600-900 psi, and shear the Auto-Fill tube out of the Insert Valve, converting it to holdback pressure.

EQUIPMENT RATINGS: Plug bump, back pressure and temperature ratings are as follows:

SIZE MAX. PRESSURE (psi) MAX TEMPERATURE4-1/2" thru 9-5/8" 1000 250 F

10-3/4" thru 13-3/8" 500 250 F

NOTE: Specify "STC" type for use with 8-5/8" & 9-5/8" STC couplings and "LTC" type for 8-5/8" & 9-5/8" LTC couplings.

"ER" Type in smaller sizes may be used with STC or LTC couplings. "ER" Type in 10-3/4" & larger sizes are for STCcouplings only.

INSTRUCTIONS FOR ASSEMBLY AND OPERATION OF THE SURE-SEAL 3 PRESSURE DE-ACTIVATED AUTO FILL DEVICE

Unless otherwise requested, the Pressure De-activated Auto Fill device will be shipped with all of the shear screwsinstalled. Since this device was designed to provide auto-filling capability for Sure-Seal 3 equipment, it may arrive invarious stages of assembly depending on order specifications. Some possible configurations in which it may be shippedare as follows:

Configuration:

1.) The device can arrive assembled complete and ready to use installed in the float equipment, pre-set for a specifieddownhole tripping pressure.

2.) The device can arrive assembled and taped to a Sure-Seal 3 valve, which has been drilled and tapped to accept thedevice. This situation allows remote manufacturing to cement the valve in a piece of float equipment as usual. Thenwhen requested, the device can be set for the desired trip pressure and thread locked on to the corresponding valveplunger as illustrated in Dwg# WFCA0199.

3.) The device can also be retrofitted to existing Sure-Seal 3 float equipment. Since this procedure requires drilling andtapping of the already cemented valve stem, the device will arrive pre-assembled accompanied only with an optionavalve stem drill guide. The drill guide will only be shipped with the device if requested, since the guide is reusable.

Important Note: Since all of the shear screws will be installed prior to shipping, any adjustments to tripping pressureshould be made before thread locking the device to the valve stem. Once thread locked it is not possible to remove oadd additional shear screws (See the pressure trip range and pressure per screw value listed on the appropriateassembly drawing attached).

Assembly:

Config. #1 - No assembly required. Equipment is ready for use. However, it is recommended that the trip pressure beconfirmed with what was ordered or desired (Trip pressure should be marked on OD of the tool and theoutside of the crate. Verify by counting shear screws).

Config. #2 - Cement the valve in the proper shell per the appropriate assembly drawing and Gemoco cementing spec#99100003.

Set the auto-fill device to the desired trip pressure by removing the proper number of screws required tolower the trip pressure from the maximum to the desired setting (Refer to the corresponding assemblydrawings for the pressure per screw value based on which design range device you are setting. Forexample, 500 psi per screw for the 1,000 – 6,000 psi range [Dwg # WFCA0243] and 1,700 – 6,000 psi range[Dwg # WFCA0242], 890 psi per screw for the 2,800 – 10,680 psi range [Dwg # WFCA0241] and 710 psi perscrew for the 2,200 – 17,040 psi range [Dwg #WFCA0244]). Remove screws in a symmetrical patternalternating screw/hole/screw whenever possible.

Brush a thin layer of Tube-Lok (Approximately ½ tsp, .08oz, or 2.4 ml) on to the threaded aluminum stud andin the corresponding hole to insure a good bond without excessive overflow when assembled. Caution: Anexcessive overflow of the Tube-Lok compound may unintentionally bond other parts together creating apotential malfunction of the valve or the auto-fill device.

If available, 2-3 drops of 400 F Loctite #620 can be substituted for Tube Lok, which can be difficult to mixproperly in small quantities.

While depressing the plunger, with a suitable tool (preferably a piece of PVC pipe or equivalent non scaringmaterial), screw on the auto-fill device by hand until it is snug. Continue to tighten the connection securelyby using a 3/16” Allen wrench (large flathead screwdriver on the 2,200 – 17,040 psi range device) on the freeend of the device (Do not over tighten, use approx. 5 ft lbs of torque).

Check that the device is holding the plunger in the “Set Position” as illustrated in Dwg# WFCA0199. Thenallow the Tube-Lok to cure for a minimum of 45 minutes before equipment is put into service (Mark the setpressure on the OD of the tool for quick reference later).

Config. #3 - To retrofit the auto-fill device to existing float equipment, start by identifying which valve size you are dealingwith (This device is designed for 2-1/2” or 3-1/4” Sure-Seal 3 valves only). The plunger stem diameter isdifferent for each size. Since the plunger must be drilled and tapped to accept the auto-fill device, the properdrill guide must be employed (Request the desired drill guide size when ordering the retrofit kit).

Place the drill guide over the end of the valve stem and hold secure. Insert an extra length size “F” (.257”)drill bit into the drill guide and drill a 1.25” deep hole for tapping (Use of a drill stop or depth mark to limit the

drill depth is recommended).

Remove the drill guide and clean out the cuttings from the hole in preparation for tapping. Use a 5/16” – 18UNC 2A tap and proceed to cut threads to a minimum dept of 1.0”.

Clean out cuttings from the hole and the valve prior to attaching the auto-fill device. To attach the devicefollow the steps in configuration #2 starting with the second step.

NOTE: Some models may not accommodate this device due to special configurations that either prevent its function orattachment (such as double valve, aluminum nose, and hard to reach valves). An extension for the drill bit andtap may be required for float shoes. If the retrofit is questionable, contact Gemoco Engineering Department forapproval.

Operation: Calculate derived de-activation pressure based on true vertical dept (TVD) and mud density. (Hydrostaticpressure in PSI = TVD (ft) x Mud Density (ppg) x .052).

Following preceding instructions, set the auto-fill device to the desired trip pressure, and secure to valve withTube Lok.

Makeup float shoe and/or float collar onto casing string. Apply Weatherford Tube Lok compound to thelower six shoe joint thread connections (pin end only) to prevent the shoe joints from backing off duringDrillout.

Upon running the auto-fill equipment into the well, the mud level inside the casing should be seen to risefairly quickly as an indication the equipment is operating correctly. The casing fluid level should be checkedvisually throughout the job to ensure that the valve is operating correctly. The driller will also be able tomonitor the hook load and fluid returns as a guide to the equipment operation.

If the casing stops filling before reaching setting depth, simply rig up a swage and break circulation.Displace the capacity of the casing, then go back to running the casing. If overfilling of the casing occurs,heavier mud may be pumped into the casing to counteract the imbalance or an overflow line may be riggedup. Once the casing is landed, rig up the swage or cementing head and establish circulation.

Circulation during the casing running operations is acceptable, provided the circulation rate is kept below 10bbl/min.

The de-activation is automatic and will occur when the hydrostatic pressure surrounding the equipmentexceeds the set pressure +/- 15%. When the auto-fill device trips, the casing stops filling automatically. Thefloat equipment then acts as conventional float equipment to hold back pressure.

If TD is reached without evidence of the auto-fill device tripping, additional hydrostatic pressure may beapplied by pumping fluid into the casing with the annulus blocked. Higher density fluids, casing movementand flow also increase the hydrostatic pressure downhole.

WEATHERFORD ELASTOMERS CEMENTING PLUGS FLUID

COMPATIBILITY AND RATINGS

The plug bump pressure rating is the maximum differential pressure that may be applied above the top cementing plug after landing ona Float Collar. Weatherford Elastomer Cementing Wiper Plug bump pressure capabilities exceed float collar ratings shown in sizes 5½” and larger.

Weatherford Elastomers urethane cementing plug fin and core materials have been tested in numerous drilling fluids and have been

found to be compatible with all fluids tested provided the operating temperature is no greater than 250 F (121 C). Fluids testedinclude water, mineral oil, diesel, isomerized olefin, linear alpha olefin, ester, LAO/IO blend, chemical wash, and spacers. Chemical

wash was the only fluid tested that was borderline for acceptance at the 250 F testing based upon physical changes in fin materialonly. When cementing plugs are used to separate fluids including chemical wash, it is recommended that the plugs be launched within

the other fluid (not within the chemical wash) when approaching 250 F. Tests and field runs of the Weatherford Elastomer urethane

cementing plugs with fluids other than chemical wash indicate acceptable performance at bottom hole static temperatures up to 300 F

(150 C).

Weatherford Elastomer nitrile plugs have been tested in the same fluids as the urethane plugs and have been found to be compatible

with these fluids at temperatures up to 400 F (205 C). The ester base fluid was the only fluid tested that was borderline for

acceptance at the 400 F testing based upon physical changes in nitrile fin material.

Wear tests indicate the urethane fin materials wear at approximately one-half the rate of nitrile fin materials and the stiffness of the

urethane fins is greater than most nitrile plugs. The urethane plugs are therefore recommended for all applications below 250 F and

some limited applications up to 300 F. Nitrile plugs are recommended for higher temperature applications up to 400 F.

Plug bump pressure ratings are dependent upon the temperature of the application and the type of float equipment used. Most ratings

are based upon bump pressure tests performed at 250 F to 300 F temperatures. Please refer to the Weatherford Float EquipmentTechnical Manual for cementing plug / float equipment pressure ratings. Higher ratings may be possible at lower temperatures.Contact Houma Engineering at (985) 872-3265 for special applications information.

SURE SEAL 3 STANDARD FLOAT EQUIPMENT FLOW ANDTEMPERATURE RATINGS

The flow durability rating of float equipment is based on the ability of the equipment to resist erosion when exposed to acirculating fluid. API RP 10F, Recommended Practice for Performance Testing of Cementing Float equipment, describesthe circulating fluid, test apparatus, pump rates and back pressure values.

The circulating test fluid consists of a water based drilling fluid with the following characteristics at 120 F:

Density : 12.0 – 12.5 lb/gal (1.44-1.50 kg/L)

Plastic Viscosity : 10-50 cp

Yield Point : 5-25 lb/100 ft2 (2.4 – 12.0 Pa)

10-s gel strength : > 4 lb/100 ft2 (1.9 Pa)

Sand content : 2-4 percent by volume of 80-200 mesh silica sand

Flow durability testing for regular equipment is based on the chart below:

Category Duration1 (hr) Maximum2 Pressure psi (kPa)I 8 1,500 (10,300)

II 12 3,000 (20,700)

III 24 5,000 (34,500)

1 Circulation Rate is 10 bbl/min for float equipment larger than 3 ½” and 6 bbl/min for equipment smaller than 3 ½”.

2 Maximum test pressure should be the lesser of the value shown or 80% of the manufacturer’s rated burst or collapse fo

the float equipment casing, whichever is applicable.

The High Temperature and High Pressure portion of the API test procedure is broken into three categories as describedbelow:

Category Temperature1 F ( C) Maximum2 Pressure psi (kPa) A 200 (93) 1,500 (10,300)

B 300 (149) 3,000 (20,700)

C 400 (204) 5,000 (34,500)

1 Duration at temperature is 8 hours for all categories

2 Maximum test pressure should be the lesser of the value shown or 80% of the manufacturer’s rated burst or co llapse fo

the float equipment casing, whichever is applicable.

The 2 ½” , 3 ¼” , and 187E Sure Seal 3 valves are all rated to the highest category in temperature, pressure and flowresistance, IIIC.

The following data is based on circulation times with the API specified fluid. Testing has shown that the API specified fluidis approximately ten times more abrasive than a 12 ppg water based drilling mud. Flow endurance with a clean drillingfluid will be greatly increased over the values below.

7-178

FLOAT EQUIPMENT AND PLUGS ROLLER CONE BIT DRILLOUTRECOMMENDATIONS

The drill out procedures presented below are recommended guidelines and do not cover all situations. Final decisions onhow to drillout should be controlled by the operator and within bit manufacturer’s limits of operation.

GENERAL COMMENTS:

Apply Weatherford Tube LokTM

Compound to the bottom six thread connections and the float equipment threads. Apply tothe pin thread only. This helps prevent the shoe joint from backing off during drillout.For standard plug sets the top cementing plug should be released while pumping cement. Pump an additional 10 feet(three meters) of cement on top of the plug. Non-rotating plugs do not require cement to be pumped after the top plug.Make up BHA with a near bit stabilizer.Check the bit diameter with the float equipment drillout diameters to verify clearances. A junk basket may be used near the bit to catch large pieces of materials.Use an insert or mill tooth type bit (for medium formations) for faster drillouts.

Do not use a bit that has or has had a locked cone or that has shown some locking tendencies previously. Any "used"bits should be researched as to under what conditions they were pulled previously.Do not use any type of automatic driller.Do not "spud" or sit the bit weight suddenly on the plugs or float equipment.Two things to watch for are that you do not bury the bit and thus stall out which can damage a cone by locking it up withinseconds or minutes, and that you do not pump the bit off bottom. This is usually a result of not cleaning the rubber out ofthe hole that was part of the plug fins.If hole cleaning seems to be a problem, use a viscous pill to sweep out cuttings, instead of increased pump rate.

DRILL OUT PROCEDURE:

1. Start rotation above the wiper plugs/float collar, approximately 30 rpm while circulating.

2. Adjust pump rates to achieve a ratio of 1.5-2.0 hydraulic horsepower per sq. in. of bit area. Some operators use 40gpm per inch of bit diameter as a starting point.

3. Ease into plugs, increasing rpm to 40 - 60 rpm.

4. Increase WOB (weight on bit) using 2,000 - 3,000 lbs. per inch of bit diameter.

5. Monitor penetration rate and adjust WOB as required.

6. Raise the BHA and bit once through the plugs (approx. 2ft.), again after drilling midway through the float collar, aftercompleting the float collar or as often as dictated by hole conditions.

FLOAT EQUIPMENT AND PLUGS PDC BIT DRILLOUTRECOMMENDATIONS

The drill out procedures presented below are recommended guidelines and do not cover all situations. Final decisions onhow to drillout should be controlled by the operator and within bit manufacturer’s limits of operation. Placing 10 feet ofcement above the top plug is recommended to improve drillout.

GENERAL COMMENTS:

Apply Weatherford Tube LokTM

Compound to the bottom six thread connections and the float equipment threads. Apply tothe pin thread only. This helps prevent the shoe joint from backing off during drillout.

If possible, the top cementing plug should be released while pumping cement. Pump an additional 10 feet (three meters)of cement on top of the plug. Non-rotating plugs are recommended for drillout applications where minimal or no cementcan be placed above the top plug.

Make up BHA with a near bit stabilizer as close to the bit as possible.

Check the bit diameter with the float equipment drillout diameters to verify clearances.

A junk basket may be used near the bit to catch large pieces of materials.

Do not use any type of automatic driller.

Do not "spud" or sit the bit weight suddenly on the plugs or float equipment.

DRILL OUT PROCEDURE WITH PDC BIT ON DRILL STRING:

Before tagging the top plug, turn drill string at 45-65 RPM, and slowly lower drill string onto top plug or top of cementabove the plug. After tagging the top of the cement or top plug, turn drill string at 60 - 80 RPM and pump at a sufficientflow rate to remove drilled cuttings. Some operators use 40 - 50 GPM per inch of bit diameter as a starting point. Slowlyapply 2,000 pounds (909 kg) weight on bit (WOB) until the bit pattern is made. Slowly build WOB to 3,000 to 5,000

pounds (1,363 to 2,272 kg).

Maintain 3,000 to 5,000 pounds (1,363 to 2,272 kg) WOB while drilling the float equipment.

If the rate of penetration (ROP) slows or the torque increases, the bit should be raised while continuing to rotate andcirculate. Slowly lower the bit and follow the above recommendations. This helps remove debris and cementing plugwipers.

If the ROP stops or the torque declines, this could indicate that the bit is spinning without cutting. Stop rotating, reduce the flow rate to two or three BPM, and put 3,000 to 5,000 pounds (1,363 to 2,272 kg) WOB

(Note: High flow rates will decrease the effective WOB). Pick-up and begin rotating to 40 – 60 RPM. Slowly set down increasing WOB to 5,000 to 6,000 pounds (2,272 to

2,726 kg).

Resume drilling with original parameters once normal drilling characteristics are observed.

If the drillout characteristics change, i.e. drill pipe or rotary table starts vibrating excessively, change either the WOB,RPM, or the circulation rate until the drillout characteristics normalize. Resume drilling with the original parameters oncenormal drillout characteristics are observed.

Convex bits tend to perform better when drilling out plugs and float equipment than do concave bits, since convex bits areless likely to trap foreign materials under the bit.

If the ROP stops and cannot be restarted using the above recommendations, then retrieve the bit for inspection.

DRILL OUT PROCEDURE WITH PDC BIT AND MUD MOTOR:

Before tagging the top plug, pump at a sufficient flow rate to have motor turning at 100 – 150 RPM. The motor type willdetermine this pump rate for RPM desired. Turn the drill string at 25 – 30 RPM. While monitoring the circulation pump

pressure, slowly build WOB until the pump pressure increases. Hold drill string at this position until the pressure subsidesthen inch down until pressure starts to rise again and repeat process until completely through the equipment.

If pressure can not be monitored, then slowly apply 2,000 pounds (909 kg) WOB until the bit pattern is made. Slowly buildWOB to 3,000 to 5,000 pounds (1,363 to 2,272 kg). With motor bits use optimum weight and RPM which will not stall bit.Maintain 3,000 to 5,000 pounds (1,363 to 2,272 kg) WOB while drilling the float equipment.

If the rate of penetration (ROP) slows or the torque increases, the bit should be raised while continuing to rotate andcirculate. Slowly lower the bit and follow the above recommendations. This helps remove debris and cementing plugwipers.

If the ROP stops or the torque declines, this could indicate that the bit is spinning without cutting. Stop rotating and put 3,000 to 5,000 pounds (1,363 to 2,272 kg) WOB.

Pick-up and begin rotating motor to 40 – 60 RPM and drill string to 25-30 RPM. Slowly set down increasing WOBuntil circulation pressure increases or to 5,000 to 6,000 pounds (2,272 to 2,726 kg). Resume drilling with original parameters once normal drilling characteristics are observed.

If the drillout characteristics change, i.e. drill pipe or rotary table starts vibrating excessively, change either the WOB,rotary RPM, or the circulation rate until the drillout characteristics normalize. Resume drilling with the original parametersonce normal drillout characteristics are observed.

Convex bits tend to perform better when drilling out plugs and float equipment than do concave bits, since convex bits areless likely to trap foreign materials under the bit.

If the ROP stops and cannot be restarted using the above recommendations, then retrieve the bit for inspection.

BALLSEAT INSTALLATION:

The valve requires a trip ball to convert the valve from an automatic fill device to a standard float valve. The valve can beconfigured to accommodate a variety of trip ball sizes from 1-1/2” to 3-1/2”. The Auto-Fill Tube has a 3-3/4” bore with a 3-1/4” ballseat inside diameter. The tube will accept a 3-1/2” trip ball. An optional ballseat kit must be used if a trip ball sizefrom 1-1/2” to 3” is desired.

Prior to making the Large Bore Auto-Fill Flapper Valve up onto the casing string, the ballseat size should be verified andpossibly adjusted. The following chart lists the ballseat kit model numbers, their inside diameters, and the size of trip ball

for which they were designed. A measurement of the Ballseat's inside diameter can verify which ball size the valve isconfigured for.

To remove a pre-installed ballseat, use an "L" shaped, 1/8" hex wrench to loosen the three 1/4" set screws around thebottom of the Auto-Fill Tube. The ballseat can then be pushed from the pin end of the float collar and removed from the

box end of the float collar.

To install a ballseat into the float collar, insert the ballseat into the Auto-Fill Tube from the box end of the float collar. Slidethe appropriate ballseat through the tube until it rests on the tube’s integral ballseat. Three 1/4-20 UNC brass set screwsshould be used to retain the ballseat in the bottom of the Auto-Fill Tube. Tighten the set screws to approximately 2 inch-lbf.

PRE-SET CONVERSION PRESSURE

The Large Bore Auto-Fill Float Collar has a pre-set conversion pressure. The standard conversion pressure is 500 - 700psi. Conversion at 500 - 700 psi is achieved by six (6) 1/4-20 UNC brass screws. The Float Collar can be ordered withan optional conversion pressure of 300 - 400 psi. Four (4) 1/4-20 UNC brass screws produce the optional conversionsetting of 300 - 400 psi. The pre-set conversion pressure is stenciled on the Float Collar's shell.

MAKE-UP ON CASING STRING:

Make up the float collar onto the casing string at least one joint above the guide shoe or filter shoe hanging collar. ApplyWeatherford Tube Lok

TM compound to the bottom six thread connections and the float collar threads. Apply to the pin

thread only. This helps prevent the shoe joint from backing off during drill-out.

The Large Bore Auto-Fill Float Collar can be run with a Weatherford Mudmaster filter shoe or with a guide shoe that has aminimum 5-inch bore inside diameter. The 5-inch bore guide shoe will allow the Auto-Fill Tube to pass through the nosewithout plugging it off.

If a landing collar is to be run above the Auto-Fill collar, it should have a tapered guide and a sufficient bore to allowpassage of the trip ball, if dropped from the surface.

RUNNING INTO THE WELL:

When running into the hole the valve should be monitored to confirm that fluid is filling the casing. Observation of fill canbe accomplished by several methods. One is by watching the weight indicator and graph to ensure that the string iscontinually gaining weight and not decreasing or losing weight. Another is to use a thin sheet of paper such asnewspaper placed over the top of the casing. The air being displaced out of the casing will blow a parachute effect on thepaper. However, a careful grip should be maintained on the paper so as to prevent the paper from being pulled into thecasing from a sudden vacuum formed by U-tubing effects.

Well conditions with small annular clearances can produce an overfilling effect, in which well fluids are displaced out of thetop of the casing, rather than out of the annulus. This overfill can occur at the rig floor if the mud level is relatively close tothe rig floor. This effect can be reduced or eliminated by increasing the weight of the fluid in the casing.

If the casing stops filling automatically, the casing should be filled from the surface and circulation established to clearcuttings and debris. The valve will not be affected if it is necessary to circulate during the casing running operations,provided that the trip ball has not been dropped.

ACTIVATION OF THE CHECK VALVE:

Circulation is recommended, but not necessary, before converting the valve to hold back pressure. Circulation aids in theremoval of any debris buildup on the ball seat.

Revision I 06/26/06

Drop the predetermined sized ball into the casing string when activation of the check valve is desired. Circulate theweighted ball down to the Auto-Fill Valve. A pressure of 500 psi to 700 psi (optional 300 psi to 400 psi) is required to

shear the Auto-Fill Tube from the Valve Assembly. The Auto-Fill Tube will then be pumped through the valve assembly.

Holes deviated greater than 30 degrees may require the trip ball to be circulated to the ball seat.

CEMENTING:

Weatherford WiperLok non-rotating plug sets are recommended for use with Large Bore Auto-Fill Float Collars. The topcementing plug should be released while pumping cement. Pump an additional volume of cement equivalent to 10 -15feet (three to four meters) on top of the plug. The displacement rate should be reduced to between 3 and 4 bbl/min toland plugs.

The maximum plug bump pressure is the allowable amount of pressure, above the displacement pressure prior tobumping the plugs. The maximum plug bump pressures, by size, are listed in the chart included with this document

VERIFICATION OF CHECK VALVE FUNCTION:

If leakage occurs past the Large Bore Auto-Fill Valve after displacing cement, circulate the returned displacement volumethough the valve, and check for proper operation of the flapper valves. This circulation will produce a forced opening andclosing of the flappers. This will assist in removing debris from the valve, which could cause a malfunction.

DRILL-OUT:

Large Bore Auto-Fill equipment, including filter shoes, may be drilled with roller cone or PDC bits. Recommendations forroller cone and PDC bit drill-out can be found in the Weatherford Float Equipment Manual.

The Flow – Activated Large Bore Auto-Fill Float Collar should be run with a Weatherford MudMaster filter shoe. A guideshoe that has a minimum 5-inch bore inside diameter may also be run, but at an increased risk of premature conversion.The 5-inch bore guide shoe will allow the Auto-Fill Tube to pass through the nose without plugging it off.

Make up the float collar onto the casing string at least one joint above the filter shoe hanging collar or guide shoe. ApplyWeatherford Tube-Lok




When running into the hole the valve should be monitored to confirm that fluid is filling the casing. Observation of fill canbe accomplished by several methods. One is by watching the weight indicator and graph to ensure that the string iscontinually gaining weight and not decreasing or losing weight. Another is to use a thin sheet of paper such as

newspaper placed over the top of the casing. The air being displaced out of the casing will blow a parachute effect on thepaper. However, a careful grip should be maintained on the paper so as to prevent the paper from being pulled into thecasing from a sudden vacuum formed by U-tubing effects.

Well conditions with small annular clearances can produce an overfilling effect, in which well fluids are displaced out of thetop of the casing, rather than out of the annulus. This overfill can occur at the rig floor if the mud level is relatively close tothe rig floor. This effect can be reduced or eliminated by increasing the weight of the fluid in the casing.

If the casing stops filling automatically, the casing should be filled from the surface and circulation established to clearcuttings and debris.

CIRCULATION:

Should it be necessary to circulate during the casing running operation, the circulation should be kept below 4 bbl/min to

prevent premature deactivation of the auto-fill equipment. The duration of circulation should be limited to one hour at 4bbl/min or 8 hours at 2 bbl/min prior to conversion. If after extended circulation the surface pressure drops below thepressure shown in the Conversion Pressure and Flow Rate in Various Fluids table for a given flow rate and fluid density(plus friction losses), circulation should be stopped. If higher circulation flow rates are required, the flow rate should beincreased to convert the auto-fill valves to hold backpressure.

ACTIVATION OF THE CHECK VALVES:

A pressure of 500 psi to 700 psi (optional 300 psi to 400 psi) is required to shear the Auto-Fill Tube from the Valve Assembly. The flow rate required to achieve this pressure is listed in the table above and ranges from 5 to 8 bbl/min,depending on mud density. Pump at a flow rate that will exceed the 700 psi pressure drop for the corresponding fluiddensity. A reduction in pressure should be noted when the auto-fill tube is released. The auto-fill tube will then be pumpedthrough the valve assembly.

CEMENTING:

Weatherford WiperLok non-rotating plug sets are recommended for use with Flow-Activated Large Bore Auto-Fill FloatCollars. The top cementing plug should be released while pumping cement. Pump an additional volume of cementequivalent to 10 -15 feet (three to four meters) on top of the plug. The displacement rate should be reduced to between 3and 4 bbl/min to land plugs.

The maximum plug bump pressure is the allowable amount of pressure, above the displacement pressure prior tobumping the plugs. The maximum plug bump pressures, by size, are listed in the chart included with this document.

Some operators prefer to de-activate the auto-fill equipment one joint off bottom and then run in the hole with the last jointto ensure the valves are closed. As an option, the casing can be picked up to let fluid out, then set down to verify fluid isno longer entering the casing. If leakage occurs past the Large Bore Auto-Fill Valve after displacing cement, circulate thereturned displacement volume though the valve, and check for proper operation of the flapper valves. This circulation willproduce a forced opening and closing of the flappers. This will assist in removing debris from the valve, which couldcause a malfunction.

Well conditions with small annular clearances can produce an overfilling effect, in which well fluids are displaced out of thetop of the casing, rather than out of the annulus. This overfill can occur at the rig floor if the mud level is relatively close to

the rig floor. This effect can be reduced or eliminated by increasing the weight of the fluid in the casing.

SECTION 9.

FLOAT EQUIPMENT PROBLEM RESOLUTION GUIDE

PREFACE:

Float equipment problems in the field are inevitable no matter how perfect the equipment. Care taken during handling,make-up, running, cementing, and drill-out will greatly reduce the chances of problems occurring. Use of proper floatequipment for the cementing and drilling conditions encountered will also forestall float equipment problems.

There are three general categories of problems: (1) continuous leakage (i.e., returns to the surface through the casingstring) (2) inability to circulate through the casing string, and (3) drill-out problems.

CONTINUOUS LEAKAGE:

Not all backflow through the casing is considered a continuous leak. Some backflow is expected and normally occurs inuncut (non-aerated) mud after bumping the plug. This is primarily a result of the casing expanding under the bumppressure. For example, 9,000 ft. string of 9-5/8”, 53.5 ppf casing would have a 2.1 bbl backflow with a 1000 psi plugbump pressure. Air-cut mud having 1% air (by volume) would about double that backflow volume. The backflow volumesmay also be increased by the thermal expansion in some instances where large temperature differences are involved.Therefore, a potential float equipment problem can only be positively associated with a continuous leak (normal backflowafter bumping the plug is not considered continuous even if it trickles for some time).

SLOW CONTINUOUS LEAKS:

Continuous leaks can either be classified as slow leaks or fast leaks. Slow leaks may be caused by a partially pluggedvalve (as the result of cuttings, an object inadvertently dropped or pumped downhole, lost circulation material LCM , etc.)Usually back-flushing or surging the valve two or three times can clear a plugged or stuck valve. Pressuring up on the

casing and then quickly releasing it can do this. Care should be taken not to overpressure the casing.

Since most float valves are held in place with concrete, there is a slight possibility of seepage through the concreteshrinkage zones or micro cracks. However, most leak paths through the concrete are so small that the barite in the mudwill seal it off.

Although it is quite unlikely in most cementing operations, the sealing area on the valve itself may erode with excessivecirculation at high rates creating a leak path. Weatherford float valves are designed and rated by API RP10F standardsfor flow endurance, temperature and backpressure.

If a slow continuous leak has been detected and back flushing fails to resolve the backflow, it may be necessary to shutthe casing in and hold pressure until the cement sets.

FAST CONTINUOUS LEAKS:

Eliminating fast continuous leaks after they occur is difficult. Avoiding such leaks through careful drilling practices isvirtually the only means of problem "resolution”. Specifically, avoid the common sources of fast leaks (which include): Float equipment concrete damage as a result of rough handling (e.g., dropped or excessively jarred, stab-in stinger run-into concrete too hard as evidenced by stinger damage, excessive pressure applied during bumping of plug, unusuallyexcessive backflow pressure)Pumping debris too large to pass through the float valves. Or intentionally placing objects in valve to hold it open forautofill reasons, thinking that it will successfully pump out of the valve with circulation.

7/18/2019 wft004266



Section - Page

Revision I 06/26/06


9-203

Damage to casing (e.g., casing damage and subsequent erosion/abrasion, salt zone migration into annulus, severebending stresses caused by extreme doglegs, corrosion, overpressuring the string, swabbing wireline cuts, mill defects in

casing)Connection leakage (e.g., cross-threading, improper torque, galled or dirty threads, excessive cycles of make-up / break-out, improper coupling-joint make-up at mill, incorrect thread compound applied, dropping string)

If a fast leak is found, attempt to back flush or surge the valve two to 3 times. If the slurry has been fully displaced, shut inthe casing and wait-on-cement.
