FuseTek bits are the Fusion of two

technologies of Fixed Cutter bits

– DuraDiamond® DiamondImpregnated Drill Bits

• Diamond Impregnated Mix

• Designed for hard rockapplications

• Durable, abrasion resistant

– PDC Drill Bits

• Latest Cutter Technology

• DiamondBack® Ideology

• Fast durable bits, High ROP

Compressive Strength

P e n e t r a t i o n R a t e

Impreg &ND

FuseTek overlaps the PDCand Impreg territory where:

• PDC bits are not durable

enough.• Impreg bits are not fastenough.

PDC



NOV© 45

Challenge:For applications thatare normally drilledwith a PDC bit, buthave harsh interbededlithologies with higher compressive strength.Damage to PDCcutters by encounteringdense nodules.

Benefit of FuseTek:Dual –natured cutting

structure can drill fast ,with the built-ininsurance of cuttingstructure redundancy.

Challenge:Top and Middle of section are fast / PDCdrilling, with higher CCS lithology towardsend of section forcinga bit change, usuallywhere diamondimpregnated bits arenormally used.

Benefit of FuseTek:Diamond impregnated

material enables thebit to drill to TD after PDC has worn down,reducing the need totrip for a new bit.

Lithologies : Medium to HardCutting Action : Shearing

Lithologies : HardCutting Action : Grinding

Once PDC wears, the bit drills using diamond impregnated material asprimary cutting structure, extending durability, reaching longer intervals

The FuseTek 6” FT713 drilled the Efilskiy layer

consisting of sandstone, mudstone, limestoneand dolomites, replacing four RCI bits.

Ran in a mud motor (4/5 lobes, 6.0 stage, 0.3 bend)in WB mud. It drilled two vertical intervals from 3930to 3954m and from 3963 to 4034m in total 95 meters

at an average ROP of 1.02m/hr. – POOH between runs was due to coring point.

– Dull grade - 2-2-WT-A-X-I-CT-PR.

Results:

90% longer interval vs. best offset

26% faster average ROP vs. best interval

Replaced 4 RC bits used in offset well

• Achieves greater ROP and longer distance through the Mattson Sands,offsetting TCI, Impregnated bits andPDC performance.

• It drilled a total of 214m in 67.5hrs with an averageROP of 3.17 m/h through the Mattson sands.

• 67% improvement in distance drilled through theMattson sands compared to the best offset.

• Achieved 9% higher ROP compared to the bestoffset.

The 8 ½” FT716 was run on a Baker Hughes AutoTrak modular motor assembly.

The well profile was a 20 degree tangent.

Interval: 12170 to 12990 feet (820 feet)

ROP : 20.2 fph. DTF

The average PDC bit run ranges from 90to 250 feet, with an average penetrationrate of 15 fph, depending on the

percentage of chert encountered. The bit drilled through very dense 80-90%

chert and was still drilling ahead when itwas pulled 170 feet from TD.

The objective was to drill the 8.5” vertical section of the Plover formation• Lithology: Hard abrasive sandstones

• Drive : Rotary

The bit achieved the fastest ROP in the field, plus significant cost savings by using

rotary instead of a turbine, finishing the section without issues.

For those harder, more abrasiveapplications where durability is aconcern. Consider a SpeedDrill bitwith Pilot Section. (patent pending)

Additional benefits provided by aFuseTek Pilot: – Increased durability without sacrificing

ROP

– Impreg material provides peace of mindin hard and inter-bedded applications

– Ability to drill longer intervals, reducescost/foot and NPT.
