Operating Parameters For PDC Bits
PDC Bit

As it is mentioned in Schlumberger Oilfield Glossary, PDC Bit is a drilling tool that uses polycrystalline diamond compact (PDC) cutters to shear rock with a continuous scraping motion. These cutters are synthetic diamond disks about 1/8 in. thick and about 1/2 to 1 in. in diameter. PDC bits are effective at drilling shale formations, especially when combined with Oil Based Mud. It is also essential to understand PDC Bit Design as it will be related to the drilling parameters.
