Abstract
The hydraulic horsepower on a conventional drill rig is significantly greater than that delivered to the rock solely through bit rotation. This paper describes a project to leverage this hydraulic resource to help extend PDC bits to geothermal drilling by integrating passively-pulsating, cavitating nozzles within Polycrystalline Diamond Compact (PDC) bits for use with conventional rig pressures to improve the rock-cutting process in geothermal formations.
