... Abstract In this paper we describe two possible use cases of well productivity estimation obtained during the reservoir drilling process. The first concerns estimating a minimum and maximum value for the remaining reservoir footage that is required (beyond bit position) to achieve a target...

... and thermal fatigue. Thus, cutter technology has been the limiting factor for efficient PDC bit drilling in the East Texas Basin. Recent technological developments have produced a new, highly abrasion resistant cutter that has increased rate of penetration (ROP) and total footage drilled in addition...
