ABSTRACT:
An improved oil and gas drilling control system which utilizes improved braking and feedback technology which, in turn, permits more precise weight-on-bit control and more smooth transitions of weight-on-bit than any existing technology. In addition, the system also permits more accurate feedback and control with respect to drilling depth, pipe transitions, and rate of penetration than prior systems.
