2013-9-10  “The smooth, low-torque crushing action of roller cones is combined with the aggressive shearing of the PDC blades to improve drilling efficiency and reduce costs. The Kymera bits can successfully drill through challenging lithologies of interbedded formations and provide smoother toolface control in directional wells, delivering greater

SUPER-HARD, THICK, SHAPED PDC CUTTERS FOR HARD

2010-2-4  However PDC bits in geothermal drilling remains a field of relatively limited experience and is an area where PDC fixed cutter bits under-perform compared to roller cone bits. A new, hard, thick, shaped Stinger™ PDC has been invented that aims to provide a link between crushing and shearing of rock to improve both ROP and overall cutter life.

Upstream Oil and Gas Drilling Tubulars and Bits

Therefore, bits are designed to do their job in severe service for as long as possible. Most bits work by scraping and/or crushing the rock as part of a rotational motion. Some bits, known as hammer bits, are activated by a downhole motor which pounds the rock vertically in much the same fashion as a construction site air hammer.
