Diamant Drilling Services

Belgian fixed cutters bits

manufacturer


Founded over 15 years ago, Diamant Drilling Services (DDS), is a Belgian fixed

cutters bits manufacturer.

Our strength lays in our ability to quickly create and manufacture custom

designs.

The company has inherited a long engineering and manufacturing experience

that allow us to develop a specific drill bit for each application:

• The bit range varies from light set steel body fishtail bits to very heavy

set, or impreg matrix body bits depending of the geology.

• Sizes vary from 3 1/8 to 17 ½’’

• Bit designs can be adapted to any BHA configuration

• Cutters are selected to match the applications.

The SP619 is a very polyvalent design for big size PDC bits.

The steel body allows a blade design with a high standoff

which is very good in terms of cleaning. Typical lithology

drilled with this design can vary from soft surface formation

(a couple of thousand psi) to medium non-abrasive formation.

This bit has been run successfully on motor or rotary in the

Middle East, water or oil base mud.

The SP519 is a standard light set design in 17 ½”.

Particularly adapted for very soft and fast application where

bit balling can be observed, having only 5 blades increase

normal face volume and the 10 nozzles configuration enhance

the cooling and cleaning.

The SR619 is a reinforced version of the previous SP619.

The double row of cutters insure a enhanced quantity of

diamond on the bit shoulder periphery. This make the SR619

more wear resistant and adapted to more demanding

lithology

The SP619 is a very common design in 12 ¼” for soft to

medium application typically preferred in massive soft to

medium hard carbonate horizons: The steel resilience make

the bit keener to sustain eventual vibration. It is a standard

bit in the 12 ¼ section, shales and carbonates in the Middle

East

The SR616 12 ¼”is a wear resistant evolution of steel body bit

with 6 blades. The second row of cutter insure a strong

diamond content on the shoulder area but also the presence

of back up cutter in the bit periphery in case of unexpected

damages.

The SP616 is the 16 mm version of the previous design. With

smaller and tougher PDC this design, it is more suitable for

medium hard carbonates. This bit is successful in Asia-Pacific.

The SP519 12 ¼”is a light set design developed for soft and

fast application. This type of design has been run in Asia

pacific especially in Indonesia and has been rewarded by

many records. Typical lithology drilled with this design can

vary from soft surface formation (a couple of thousand psi) to

medium non-abrasive formation

medium non-abrasive formation

The MP519 12 ¼” is also a light set design developed for soft

and fast application. But this matrix body version can handle

higher pump rates and fluid velocity without any risk of body

erosion.

The MP616 is mid-range hardness PDC bit design. It is well

suited for medium-soft to medium type of lithology. The

tungsten carbide matrix body can withstand high fluid

velocity and minor abrasive content even with some sand

content in the mud.

The MR616 is the safe choice when the lithology is not well

known or can be challenging. This bit is a very good

compromise between bit life (wear & erosion resistance) and

drilling efficiency (good ROP). This design is perfect for

interbedded formation that range from soft to medium hard

formation. It has been run on rotary or motor, RSS

assemblies…this is a versatile bit.

The MP716 is an higher hardness-range PDC bit design. It is

well suited for medium to medium-hard type of lithology. The


velocity and minor abrasive content.

The MR716 is among the strongest bit design that can be

manufactured in 12 ¼”. The reinforced cutting structure and

the tungsten carbide body guaranty extra bit life in hard

formation or interbedded formation with hard stringers.

The MP616 8 ½” is probably one of the most common design

in the industry. Especially efficient in soft to medium lithology

it is the perfect compromise between cutting efficiency and

bit life in non-demanding application.

The MR616 8 ½” is a reinforced version of the previous

MP616. It is a multipurpose bit that delivers good

performances in a very wide range of lithology including

interbedded formations. This design has delivered record runs

in the 8 ½ sections in the Middle east, in terms of high ROP

and long meterages. It has drilled extended reach horizontal

sections with no difficulty.

The MR613 8 ½” is the 13mm version of the previous design.

This version is sometimes preferred by DD for high DLS

directional objectives.

The MR716 8 ½”is pushing the envelope of the MR616 a step

further in terms of diamond reinforcement in the cutting

structure. It still had room enough to work with 7 nozzles.

The MP813 is a higher hardness-range PDC bit design. It is

well suited for medium to medium-hard type of lithology. The


velocity and minor abrasive content, while the 8 blades bring

enough carat to handle harder lithology.

The MR713 8 ½” is the 13 mm cutter version of the previous

design.

The MR816 is among the heaviest set bit that can be

designed in 8 ½”. The diamond content has been privileged to

maximize the bit life in hard horizons with possible abrasive

content. This design is particularly adapted to deeper 8 ½

sections in the middle east below the hith.

The MR813 is the 13mm alternative of the heavyset previous

design. Diamond carat content is still very high.

The MP513 a light set small bit that is fit for purpose for soft

formation. The five hydraulics make it a well suited product

where cleaning is a priority and ROP can reach high rates

The MP613 is more of a multipurpose bit. With its balanced 6

blades, it can be used to drill re-entry as well as deep section

in soft to medium hard formation (typically carbonated

reservoir).

The MR613 is a reinforced version of the previous design.

With the additional rows of cutter it can deal with tougher

formation that eventually abrasive content.

The MP713 is among the toughest bit that can be design in

small size. Geometrically speaking it is the limit between

room for PDC and room for cleaning. The bit is design to drill

hard horizons or interbedded with abrasive content.

The MP610 4 1/8” is one of the smallest standard bit that can

be manufactured with conventional elements. The design is a

good trade-off between stability- diamond content -and good

cleaning and allow it to be use in quite a wide range of

application

The MP810 is toughest bit that can be designed in small size.

Geometrically speaking it is the limit between room for PDC

and room for cleaning. The bit is designed to drill hard

horizons or interbedded with abrasive content. It has

produced excellent results in deep Khuff wells

DDS Bit recommendation for application range

PDC cutter selection

Through test campaigns in lab and field tests validation, Diamant Drilling Services entrust the

renowned names of the diamond industries to manufacture the most appropriate compact cutter

for a specific application

Among all the products available on the market and after selection of the best, Diamant Drilling

Services consider 3 main grades to select:

• Standard: multi-purpose product that suit most of

non-demanding application

• Premium: top of the shelf product in terms of shock

resistance and abrasion

• Phoenix: High quality product with performances at

least equivalent to deep leached product

The PDC PHOENIX cutter is the cutting-edge product used by Diamant Drilling Services in challenging

application. Through a combination of multi layers technology and diamond to carbide interface

shape, this cutter has shown superior thermal resistance to rough solicitation providing enhanced

bit life and drilling performances at least as good as any surface treated cutter.

MicroCORE™ Bit Technology

Product Overview

The MicroCORE™ technology is a one-of-a-kind cutting structure design exclusive to Diamant Drilling

Services . Originally developed for Total, DDS now own the IP and have tried and prove this

technology around the world. The MicroCORE™ guaranties maximum ROP and enhanced cuttings

quality

By comparison with similar conventional drill bits, the MCB brings, thanks to its specific design, the

following benefits:

Optimized Energy: The MicroCORE cutting technology deliver more energy to the cutters than

traditional cuttings structures. Redistributing wasted energy to more efficient cutters means higher

ROP and better quality wellbore

Undisturbed Core fragment:

MicroCORE and MicroCORE’s fragments

are not impacted by the shearing process

of the cutters and provide an

undisturbed tructure for analysis in any

formation type.

Instead of wasting energy in center trying to squeeze

the central cutter into the formation, the

MicroCORE™ lets a small core grow in the center of

the bit until it reaches breaking point.

The core is naturally broken by flexion when it

reaches the body (localy reinforced).

The small core is then ejected through the annulus.

The MicroCORE design has been studied (structure

and fluid dynamics) to insure 0 risk of plugging

Sample Affected by the PDC shearing action

MCB Fragments: Unique sample of formation. Preserved texture and properties. Sample NOT Affected by the PDC shearing action

Design adaptation to BHA’s and application

All Diamant Drilling Services bit designs can be adapted to different assemblies. The bits have

been run and produced excellent results in terms of drilling but as well in terms of steerability and

DLS on rotary, motor assemblies, RSS push the bit or point the bit technologies.

DDS has conducted numerous tests to confirm the role of designs features in the stability or

steerability of the bits.

DDS recommends to conduct meetings with the BHA companies to adapt the bit designs accordingly.

Bits can be adapted to keep the angle in long horizontal sections, as well as building or dropping

angles in other sections of the wells.

Diamant Drilling Services has the ability to run Rock Strength analysis and full application analysis

and come back to the customer with an appropriate recommendation.

IADC code consist of four characters, indicating bit body, formation type, cutting structure and bit profile. • First literal code character designates the bit body material (Steel, Matrix or Diamond) • Second numerical code character (1-8) designates the formation type being drilled (5 has no code) • Third numerical code character designates drill bit cutting structure (PDC cutter size or other type) • Fourth numerical code character - bit profile

1- Inner Cutting Structure (Table 1) The first 2/3 of the radius represents the inner rows (figure 1). Using a linear scale from 0 – 8, a number is given to cutter wear in the inner rows of cutters. The grading numbers increase as the wear increases, with 0 representing no wear, and 8 representing no usable cutter left. A grade of 4 indicates 50% of cutter wear 2 – Outer Cutting Structure (Table 1) The outer row of cutters represents the third of the bit radius (figure 1). Using a linear scale from 0 – 8, a number is given to cutter wear in the outer rows of cutters. 3 – Dull Characteristics (Table 2) This is the most prominent or “Primary” physical change from the new condition of the bit. 4 – Location (Table 3) The space is used to indicate the location of the primary dull characteristic noted in the third space. Locations are as designated. X – Bearings/Seals This space is only used for roller cone bits. It will always be marked “X” for fixed cutter bits. 5 – Gauge (Table 4) This space is used to record the gauge of the bit. The letter “I” (In Gauge) indicates no gauge reduction. If the bit has any reduction in gauge it will be recorded in 1/16ths of an inch. A PDC “no go” gauge is used to ensure a bit is not smaller than allowed and it should not go or slip down the entire length of the bit. A PDC “go” gauge ensures a bit is not larger than allowed and should slip down the entire length of the bit. 6 – Other Dull Characteristics (Table 2) This space is used to record any dull characteristics of the bit in addition to the cutting structure dull characteristics listed in Table 2. Such evidence may relate specifically to cutting structure wear as recorded in the third space, or may note identifiable wear of the bit as a whole, such as “erosion” or “broken blade”. Many times, this secondary dull grade indentifies the cause of the dull characteristic noted in the third space. 7 – Reason Pulled or Run Terminated (Table 5) This space is used for the two or three letter code to record the termination of the bit run.
