Surface Drives

Weatherford PCP surface drives are rela-tively small, lightweight, and feature a

low profile requiring minimal verticalspace and easy installation. The basicfunction of the surface drive unit is tosupply the necessary speed and torqueto the downhole progressing cavity

Surface drives are available in directelectric motor drives as well as directgearbox drives that may be coupled toan electric motor or a gas engine. Awide range of hydraulic drives systemsfor both gas and electric applicationsare also available.

Subsurface PC Pumps

There are two basic components thatmake up the downhole PC pump — asingle helical alloy-steel rotor connectedto a rod string and a double helicalelastomer-lined stator attached to thetubing string. Using the latest manufac-turing technology, rotors are kept to tighttolerances and treated with chemical andabrasion-resistant coating, typically hardchrome. Stators are comprised of a steel

tube with an elastomer molded inside toprovide the internal geometry. Eachcombination of rotor/stator is matchedto downhole conditions to providehighly efficient operation and optimum

Uniform Thickness PC PumpsUniform Thickness PC PumpsPROGRESSING CAVITYPUMPING SYSTEMS

Weatherford’s Uniform Thickness Stators are manufactured with an external profile that matches

the internal geometry, as illustrated on the left. The result is a stator that has a uniform thickness

of elastomer throughout, which can lead to numerous operating advantages including:

Improved Heat DissipationAs a result of the innovative design, the elastomer runs cooler leading

to improved mechanical properties. Extensive pump inspections from

various heavy oil customers document that the majority of failures

were due to stress or wear of the stator elastomer minors. By eliminating

this portion of the stator, failures should be

drastically reduced.

Uniform Elastomer Swell / Uniform Thermal ExpansionHaving a uniform elastomer thickness means the elastomer also

swells or expands in a uniform fashion. Properly sizing the rotor for

aggressive applications is therefore much simpler.

Using Weatherford’s Uniform

Thickness technology, operators

should find PC pumps more reliable

and better suited for more

applications, than ever before.

The main objective of an Insertable PC Pump is to help reduce down time related to pulling tubing when

changing or replacing a tubing installed PC Pump. The Insertable PC Pump is installed down hole by first

installing the tubing string with a corresponding Pump Seating Nipple (PSN) and the correct amount of tubing

below the PSN at the desired pump landing depth. Once the tubing Is installed, the Insertable PC Pump

assembly is ran down hole on the bottom of sucker rod or continuous rod until it seats in the PSN, sealing

the production fluid away from the pump in-take.

Cloverleaf Design

Insertable PC Pumps "Cloverleaf Design"

• Intended for 2 7/8" tubing

• This design is similar to other conventional Insertable PC Pumps that are available

• The assembly is removed by a rod coupling on the top of the rotor, and a "Cloverleaf" pick-up acting like a no-go at the top

of the assembly

• When the rod coupling and the "Cloverleaf" meet, the pump can be pulled from the seating nipple and brought to surface

• The pump has a flush tube between the top of the stator and the "Cloverleaf" to allow the pump to be flushed and maintained.

• The flush tube is approximately the length of the rotor to allow fluid to pass around the rotor and through the stator during

a flush-by

Insertable PC Pumps "Arrowhead Design"•Utilizes patent pending "Arrowhead" technology to make Insertable PC Pumps more practical and compact

• Intended for 3 1/2" & 4 1/2" tubing

• Rotor features a special shaped Arrowhead structure on the bottom of the rotor designed to mate with a floating ring acting

as a no go at the top of the insert assembly

Applications & Considerations

Tubing & Equipment

• New or like new tubing is recommended

• Tubing should be cleaned and drifted during tubing installation

• Tubing weight is not an option, heavier tubing weights than stated may prevent insert from

being properly installed

• Recommended to have tubing below the PSN drilled with holes near the pump intake to increase flow

• Tubing below the PSN should be long enough to allow for different length of pumps to be installed

• Consider possible future pump sizes in order to get the maximum payback from the insert concept without having to pull

tubing

Well & Well Bore

• Applications with extremely high sand content may not be good candidates

• Wells with deviations near the PSN landing location may prevent the insert from being seated properly

Insert Components

• Nearly all components in the insert assembly are reusable

• Allowing only stators and/or rotors to be purchased, once the initial components are purchased• A back up assembly is recommended to reduce turn around time

• Insert tagbars are similar to conventional tagbars therefore slotting can be requested to allow for greater inflow

Operation

• Proper rotor landing is critical with the patent pending "Arrowhead" style insert pump - rotor only needs to be 8"-12" off

of the tagbar

• If the "Arrowhead" is landed in the stator it may cause a restriction and cause slight damage to the stator

Note: The pump will st ill operate normal ly if the arrowhead is landed with in the stator

Maintenance• Regular flushing can extend the life of an insert pump assembly

• Make sure flush-by or service rig crews are aware that it is an insert pump, and the know the proper procedures

Note: Drive head can be tagged or marked, advis ing an Insertable PC Pump is down hole

Open/Close Tagbar (OCT)Open/Close Tagbar (OCT)PROGRESSING CAVITYPUMPING SYSTEMS

The design of the Weatherford Open/Close Tagbar (OCT)will provide the producer with all the benefits of a non-slotted

and a slotted tagbar in one piece of equipment. The OCT gives

the producer the ability to: circulate the well through the tubing,

reduce the shock loading and costs of sand bailing problem

wells during work-overs, and allow fluid to enter the pump

through slots directly at the intake when the well is in production.

The OCT features top and bottom threaded connections that

can simply thread on and replace your existing

XL or 3XL threaded tagbar. The simplicity of the OCT makes

cleaning quick and easy, allowing for multiple reuse if your

Introduction

rogressing Cavity (PC) Pumps are a widely accepted means of artificial lift; with high production, lift capacity, and system

efficiency being a few of the major benefits over other oil and water pumping systems. The ability for PC pumps to handlesand and viscous fluids make them the best solution for heavy oil production and the high gas oil ratio tolerance is beneficial

in pumping mixtures of sand, oil, gas and water.

PC pumps are comprised of two parts - a helical shaped steel rotor and a stator. The rotor, which is the rotating internal

component of the pump, is normally driven by a rod string. It is precision machined from high strength steel and coated witha wear resistance layer, such as chrome. The stator is attached to the production tubing string and remains stationary during

normal operation. It consists of a molded elastomer permanently bonded to the inside of a steel tube.

As the PC pump operates, cavities formed between the stator and rotor move fluid upward in a non-pulsating action from theintake to the discharge of the pump. Pressure builds linearly from the inlet to the discharge of the pump providing the necessarylift to produce fluid to surface.

Selection Considerations

PC pump selection is dependent on the following conditions:

•Production requirements.

•Pump landed depth.

•Tubing and casing pressures.

•Fluid conditions.

-Density, viscosity, fluid level, sand and water content, aromatic content,

CO2 & H2S presence, temperature, and gas oil ratio.

•Well equipment configuration.

•Tubing specifications.

•Casing specifications.

•Rod specifications.

•Drive capabilities.

An important factor to consider when selecting a PC pump is the experience gained from other wells

in the area. Weatherford personnel are available to assist with well design and pump selection using

our wide network of experience and a very powerful design program developed at C-FER. In order to

complete a C-FER PC pump run, the following input sheet must be filled out completely. This program

can predict all elements of a Downhole Progressing Cavity Pumping System including:

•Pump differential pressure.•Pump speed.

•Total input power required.

Input Data Sheet

We offer the ability to predict all elements of a Downhole Progressing Cavity Pumping System including differential pressure, estimated pump speed,polished rod drive torque and total input power required for any given set of well parameters. From this information it is possible to correctly select

the bottom hole pump based on volume and lift capabilities, sucker rod diameter and grade, prime mover horsepower and surface drive type mostsuitable for your application.

Tagbar Pin

Elastomer Swell Test ParametersElastomer swell tests and gas/fluid compositional analysis are completed to assist in determining gas and fluid affects on PC stator elastomersprior to running the pump. This testing can be conducted on any well or area but is predominantly completed on higher API oils and in areas with

no previous PC pump experience.

The following are general instructions for elastomer testing:

1. Contact your Weatherford representative for information on elastomer testing labs in your area.2. Contact the lab to discuss your objectives and to determine which tests will be completed (72 hour/240 hour tests).3. Determine who will obtain the sample. (The customer or the lab).

4. Obtain a pressurized fluid sample at the well.5. Complete a swell test request form. (Forms available from Weatherford PC Pump).

6. Fax the completed request form to the lab.7. Discuss the results of the test with a Weatherford representative.

Tagbar Considerations &Selections

The tagbar is a bar or rod that is welded in high strength mechanical tubing andscrewed or welded into the pump intake. The tagbar has 2 primary purposes:

1. Used as a reference point for landing the rotor.2. Used as a safety stop to prevent the loss of the rotor and rods in the event of a

fail re to the dri e string It is not designed to s pport the rod string d ring

Installation Guidelines

The procedures listed below are intended to form a basic framework for a typical installation of a Weatherford Progressing Cavity Pumping System.

Special applications or equipment may necessitate changes to these procedures. A Weatherford Artificial Lift representative can provide assistancein formulating modified installation procedures.

1-Stator Installation 2-Rotor Installation 3-Graphs & Charts

Stator Installation

1-1 PRE-INSTALLATION

• Well cleanout procedures should be considered before running any progressing cavity pumping system.The removal of any solids (i.e. sand, coal fines) from the bottom of the wellbore is recommended with a

minimum of two meters below the well perforations or two meters below the pump inlet sub.

• The rotor and stator are matched for optimum pump efficiency.

Ensure the rotor serial number located on the rotor head (top) corresponds with the lastset of numbers on the stator.

• Tighten all pump connections between optimum and maximum torque (According

to API specifications outlined on page 17).

• If the inside diameter of the production string is less than the stator discharge connectiondiameter a tubing pup joint equivalent to the stator discharge connection diameter should be

installed above the stator. DO NOT SWAGE DOWN AT PUMP DISCHARGE. Swage to smallertubing size at least one full joint (if possible) above the stator (minimum of four feet acceptable)

1-3 SECTIONAL PUMP INSTALLATION

Stator and Tubing String:Tighten all connections between optimal and maximum API specified torques.

• Run all equipment below the PC pump (i.e. gas separator, tail joints, no-turn tool, etc.) into the

well, if required. Hang the last connection on the wellhead using tubing elevators or a dog collar.• Note: The stator is properly oriented when the serial numbers are towards the top or in the up-hole

position.

• Make sure the tagbar is properly installed (if threaded tagbar) on the bottom stator section. Installthe required sectional stator pup joint onto the top of the bottom stator section. Thread a tubingcollar onto the other end of the sectional stator pup joint to prevent tubing elevators from slippingoff.

• Tighten all connections and raise the assembly into rig's derrick, tagbar down. Connect the bottomof the tagbar onto the last connection if equipment is being used below the PC pump.

• Lower assembly into well and hang sectional stator pup joint on wellhead using a dog collar,remove the tubing collar leaving the pin end up.

• Connect a handling pup joint onto the top of the top stator section, add a tubing collar on the other

end of the handling pup joint to prevent the tubing elevators from slipping off.• Tighten all connections and raise the assembly into the rig's derrick, stator down. Connect bottomof top stator onto the top of the sectional stator pup joint. Lower the assembly into the well, hangingthe handling pup joint on the wellhead with the tubing elevators.

• Connect the next joint of tubing onto the handling pup joint. Then continually add joints of tubingand other equipment (drain, burst joint, etc.) as normal until the sectional stator assembly reaches

the required landing depth.

WARNING:

Additional couplings at the stator discharge will

restrict the fluid flow, also the orbiting motion of

the rotor can cause increased tubing wear and/or

possible rotor failure. Therefore whenever possible

connect the first sucker rod directly to the rotor or

the longest pony rod as possible.

2-1 ROTOR LANDING (CONTINUED)

• If a tubing anchor catcher is used, difference in thermal expansion between the tubing and rod string may need to be considered.

*THIS IS ONLY A GUIDELINE. EACH FIELD HAS INDIVIDUAL AND UNIQUE CHARACTERISTICS

THAT NEED TO BE MONITORED AND ANALYZED TO ESTABLISH THE PROPER ROTOR LANDING.

THE CFER PC PUMP PROGRAM CALCULATES ROD STRETCH BASED ON ALL OPERATING PARAMETERS.

• The rotor should now be in the operating position. Do not lift the rotor from this position. Landing with least amount of rotor sticking out of the top of thestator minimizes downhole vibration.

• Measure the height of the wellhead drive.

• Add the length of the well head drive assembly to the operating position. This becomes the clamping point. Allow an additional 6" to 12" for polished

rod to stick up above the clamping point.

• DO NOT leave wrench marks on the polished rod.

• Install a polished rod clamp to support the polished rod on the well head drive.

A second rod clamp may be installed above the first clamp to prevent polished rod slippage.

2-2 ROTOR AND ROD STRING

Tighten all connections between optimal and maximum API specified torques.

• Connect the required sectional rotor pony rod onto the top of the bottom rotor

section (typically the API box end).• Tighten the connection and raise the assembly into the rig's derrick, rotor down.

Lower assembly into tubing, hanging the sectional rotor pony rod on thewellhead with the rod elevator.

• Connect a hanging pony rod onto the top of the top rotor section(typically the API pin end).

Identification of the Most CommonStator and Rotor FailuresPump inspections performed by Weatherford pump shops provide the user with general pump conditions. The following provides information

on identification, cause and possible solutions for each condition. For a more detailed pump analysis please contact your Weatherfordtechnical support representative.

Stator Conditions:Condition - WornIdentification

The efficiency of the stator has decreased. The interference fithas been reduced due to the general operation of the pump.

Cause

•High rpm.•Normal wear.

•Incorrect interference fit.•Abrasive fluids.

Possible Solution

•Increase to a larger volume pump to lower rpm.•Ensure pump efficiency is matched for application.

•Ensure correct elastomer.

Condition - Hardened (No photo)Identification

The stator elastomer surface is harder than it was originally


58/319

®

Condition - Missing Rubber IdentificationThe areas of missing rubber are typically hard, shiny and irregular in shape.

Cause

•Excessive pressure per stage.•Fatigue of the rubber due to cyclic stresses.•High production fluid temperature.

Possible Solutions

•Increase to a larger volume pump to lower pump rotational speed.•Ensure pump efficiency is matched for application.•Ensure pump has enough lift.

Condition - SwollenIdentification

Cross-section of elastomer is swollen resulting in an altered geometry from new.

Swollen stators may exhibit poor volumetric efficiencies and high rod string torque.

Cause

•Exposure to fluids that are not compatible with the elastomer

Possible Solutions

•Check elastomer/fluid compatibility.

•Review chemical treatment programs.

Condition - Burnt Out Identification

Rubber surface will be hard brittle and extensively cracked

Normal Swollen


59/319

Rotor Conditions:Condition - Base Metal Identification

Extreme abrasive wear through the chrome plating and into the rotor basemetal on the major diameter of the rotor.

Cause

•Producing highly abrasive fluids.•Incorrect landing procedure causing rotor/tubing contact.•Production of large foreign particles.•Excessively tight rotor/stator interference fit

Possible Solutions

•Insure proper landing procedures are followed.•Complete thorough wellbore cleanouts.•Use a customized tagbar that will limit inflow of large debris.

•Ensure correct rotor/stator interference fit for the application.

Condition - BrokenIdentification

The rotor is in two pieces.

Cause

•Rotor breaks are usually caused by excessive torque or cyclic fatigue stresses.

Possible SolutionsFatigue breaks:•Ensure proper landing procedures are followed.•Avoid landing stator in severe doglegs

Torsional Fatigue


60/319

®

Condition - General Wear IdentificationThe chrome surface is highly polished.

Cause

•Normal wear

•High rpm.•Incorrect interference fit.

•Abrasive fluids.Possible Solutions

•Increase to a larger volume pump to lower rpm.

•Ensure pump efficiency is matched for application.•Ensure correct elastomer.

Condition - PittingIdentification

Small to large holes in the chrome surface that may or may not extend down into the

base metal of the rotor. Pitting can be seen anywhere along or throughout the entirelength of rotor in either the major or minor diameters.

Cause

•Corrosive elements such as H2S, CO2 within the wellbore fluid.

Downhole AccessoriesBelow is a list of the main downhole accessories used to enhance and lengthen the life of progressing cavity pumpingsystems. Please contact your local Weatherford Artificial Lift representative for more information.

1 Corod ® Continuous Rod

Continuous sucker rod is unique because unlike conventional sucker rod it requires couplings only at the top and bottomof the rod string.

Advantages of Corod:

• Reduces pin and coupling failures.• Prolongs life of tubing especially on directional and horizontal wells.• Lowers torque and power requirements.• Reduces flow losses through the tubing.

2 Tubing Rotator The majority of tubing failures occur due to rod/tubing contact always at the same spot. A tubing rotator allows the operatorto rotate the tubing to lengthen its life. The tubing rotator can be operated by:

• Manual.• Hydraulic.• Electric.

3 Torque Anchor or Tubing Anchors

The natural action of a PC pump on the tubing string connection is counterclockwise; therefore causing the potential forthe tubing to be backed off. By installing a torque anchor/tubing anchor the chance of backed off tubing is greatly reduced.

4 Open/Close Tagbar (OCT)


62/319

®

Suggested Makeup Torque for TubingRecommended makeup torque is listed in the table below for common sizes, weights and grades of tubing. Note that PC pump

stators should be treated as Grade J55. These values have been extracted from API Recommended Practice 5C1 “Recommendedpractice for Care and use of Casing and Tubing”. The torque values listed below represent the optimum makeup torque. The

minimum and maximum torque are 75% and 125% of the optimum value, respectively.

The joint life of tubing under repeated field makeup is inversely proportional to the makeup torque applied. Therefore, in wells

where leak resistance is not a significant factor, minimum field makeup torque should be used to prolong joint life.

4E, E = EccentricityP

R, Rotor

Pitch Length

DR, Rotor Diameter

There are two basic components that make up the downhole

PC Pump - single helical alloy-steel rotor connected to a

rod string and a double helical elastomer-lined stator

attached to the tubing string. Using the latest manufacturing

technology, rotors are kept to tight tolerances and treated

with a chemical and abrasion-resistant coating, typicallyhard chrome. Stators are comprised of a steel tube with

an elastomer molded inside to provide the internal

geometry. Each combination of rotor/stator is matched to

downhole conditions to provide highly efficient operation

and optimum production enhancement.

As the rotor turns eccentrically in the stator, a series of

sealed cavities forms and progresses from the suction to

the discharge end of the pump. The result is a non-pulsating

positive displacement flow with a discharge rate

proportional to the rotational speed of the rotor and the

differential pressure across the pump.
