How to increase the rock-breaking efficiency is the prerequisite for improving the rate of
penetration (ROP) in drilling. At present, the roller cone bits and Polycrystalline Diamond …

The study on PDC cutters has a long history and is a key part of PDC bit technology. As
today's geo-energy drilling demands continuously challenges the technology capabilities …

The Stinger PDC cutter has been widely used for deep hydrocarbon and geothermal drilling
because it can significantly improve the rate of penetration (ROP) and extend PDC bit life in …

Swirling impeller abrasive water jet (SAWJ) is a viable alternative for larger-diameter drilling
of mining and oil and gas extraction. Abrasive material plays an important role in eco …

The Stinger PDC cutter has high rock-breaking efficiency and excellent impact and wear
resistance, which can significantly increase the rate of penetration (ROP) and extend PDC …

The surface geometry of polycrystalline diamond compact (PDC) cutters has a considerable
influence on their rock-cutting mechanism. In the study reported here, to study the …
