1 . Descriptions:
What is PDC in Drilling Tools?
PDC stands for Polycrystalline Diamond Compact, a cutting material used in drill bits for oil and gas drilling.
PDC bits are made with synthetic diamond cutters, known for their
extreme hardness and wear resistance. These bits have
revolutionized the drilling industry by increasing drilling
efficiency, longevity, and cost-effectiveness.
Advantages of PDC Drill Bits
High Durability: PDC cutters are extremely hard, providing
long-lasting performance.
Fast Penetration Rate: The sharp cutting edges allow for efficient
drilling.
Cost-Effective: Longer lifespan reduces the need for frequent bit
replacement.
Versatile Application: Suitable for soft to medium-hard rock
formations
2. PDC Bit Specification:
Polycrystalline diamond compacts PDC bit in the Oil and Gas
Industry PDC bits get their name from the polycrystalline diamond
compacts used for their cutting structure. A PDC bit is a drill bit
fitted with industrial diamond cutters instead of hardened metal
teeth.

4 . Drill Bit PDC Cutters
Polycrystalline Diamond Composite (PDC) cutters are the main point
of contact for a drill bit. PDC bits remove the rock mainly by
shearing.
The PDC cutters are exposed to a lot of heating and cooling down
the well, a very challenging environment.
PDC cutters that have lower thermal degradation and more thermal
stability generally achieve higher ROP and increased wear
resistance. So, optimizing the cutter is important.
5. PDC Drill Bit Nozzles
PDC Drill bit nozzles help clear the cutting area and cool the
Polycrystalline Diamond Composite (PDC) cutters.
Effective placement of these nozzles along with the angle they are
set at plays a critical role on how efficient the drill bit
performs.
Fluid channels also complement nozzle placement to improve the
clearing of cuttings.
6. Steel Body PDC Bits
Steel body of PDC Bit is the opposite of matrix body. It can of
withstanding high impact loads, but is softer and lacks protective
features. The strength and ductility of steel give steel-bit bodies
high impact resistance.
Steel bodies are considerably stronger than matrix bodies.
A beneficial feature of steel bits is that they can easily be
rebuilt a number of times because worn or damaged cutters can be
replaced rather easily. This is a particular advantage for
operators in low-cost drilling environments.
Polycrystalline diamond compact (PDC) drill bits are different than
roller cones in that they are one piece bodies with no moving
parts. The fixed-cutters shred the rock, so the bit is able to
operate with higher rotation speeds more efficiently in
consolidated formations.
