PDC drill bit

PDC stands for Polycrystalline Diamond Compact which refers to the cutters on these drill bits. PDC bits have exceptional rates of penetration when drilling & can out preform other bits in the right conditions. The diamond cutters are 10 times stronger than steel and PDC bits are most effective when drilling through shale, salt, clay, stone, sand, and concrete.

Advantage of pdc drill bits                  

* Increase penetration rates in oil and gas wells

* Reduce drilling time and costs

* Bit cost varies from 2%-5% of total cost, but bit affects up to 75% of total cost

* Cutters

- consist of thin layer of bonded dimond particles plus a thicker layer of tungsten carbide

* Diamond

- 10x harder than steel

- 2x harder than tungsten carbide

- Most wear resistant material

Applications:

* PDC bits are used primarily in deep and/or expensive wells, and are effectively used in soft-medium hard formations.

* Advances in metallurgy, hydraulics, and cutter geometry

* PDC bits drill longer and more effectively

* Most effective in very weak, brittle formations(Sandy, silty claystone, siliceous shales)
