Abstract

10,000 ft horizontal drilling and hydraulic fracturing with 24 to 36 stages are prominent in Bakken petroleum system with great success. Although advanced automated drilling system with cutting edge comprehensive logging units are available from service providers to obtain various data assisting comprehensive real-time analysis, conventional positive displacement motor (PDM) with mud-pulse (MP) measurement while drilling (MWD)/logging while drilling (LWD) system is still widely applied in this area to steer and navigate the well bore in pay zone with cost-effectiveness and efficiency. In this paper, several field cases for MP MWD/LWD systems will be discussed and lessons will be summarized to help optimize rate of penetration (ROP), reduce non-productive rig time, and improve operators drilling practices.
