Prism shaped-cutter technology
Drill in tough applications with efficientcutting action and durability

Applications• Carbonates, anhydrites, salts,
and pressured shales• Hard and/or abrasive formations
The Prism™ shaped-cutter technology
from Baker Hughes provides strategicallyplaced point loading in the cutting
structure to deliver peak penetration
rates in tough, ductile formations
interbedded with hard formations
without sacrificing durability. The Prism
shaped cutter provides point loadingby distributing more weight to a smaller
portion of the rock, and the uniquethree-dimensional shape also provides
a plowing effect to further increase
cutter efficiency. This allows a drill bit
modified with this shaped-cutter
technology to penetrate ductile
formations and generate maximum
rate of penetration.
Baker Hughes has also incorporated
elements of the StayCool™ 2.0
shaped-cutter technology into thePrism shaped-cutter design to improve
durability in hard abrasive applications.
Bit performance in hard, interbedded
sandstones and carbonates is directly
related to the cutters ability to withstandheat. The integration of the StayCool 2.0
technology reduces heat generation
at the cutter/rock interface with an
exceptionally wear-resistant working
surface, maintaining a sharper cuttingedge to maximize drilling efficiency.

The Prism geometry and StayCool 2.0
technology feature have been
fine-tuned and applied successfully to
Baker Hughes drill bits to maximize therate of penetration (ROP) and durability
through challenging ductile andinterbedded formations.
Our shaped-cutter technology has been
rigorously designed and tested using
a structured development process
to provide the most efficient cutter
geometry for specific applications.
These geometries have been vetted withindustry leading lab testing facilities anddigital drilling and integrity simulations.
The full-bit testing showed a 25%
increase in ROP drilling a carbonate
with a corresponding 25% decrease
in mechanical specific energy (MSE)for the Prism shaped cutter versus a
conventional round cutter.

• High mud weight applications

Benefits• Superior ROP• Excellent durability andabrasion resistance• Optimized drilling efficiency• Lower drilling costs

Advanced modeling optimizes
cutter placement, performance
To deliver optimal performance, theplacement of the shaped-cutters in
the right locations within the cutting
structure to suit a specific application
is just as important as the cutter design
and technology. Our Tetrahedron 3D bit
drilling simulation software evaluatesbakerhughes.com

cutter and bit body interactions
with the rock. Complex formation
types are modeled, and field-based
parameters are used to create adigital twin of the target application.
The proprietary cutter force models
have been calibrated by lab tests fromthe high-pressure simulator drillinglab. The customized cutter placement
optimization process includes theTetrahedron performance analysis

that determines the ROP response
and bit aggressiveness for the given
cutter layout, rock properties, anddrilling mode. The simulation is set up
to accurately reflect the application
description and is calibrated to reflect
the bit damage identified by the dull
study for the application. Using thispowerful software, our service delivery
teams determine the selection of thebest drill bit frame for the applicationand establish the ideal placementof Prism cutters to maximize ROPand footage.
