Paper Number: SPE-223722-MS
... in drilling automation by regulating surface weight on bit (SWOB), top drive torque, or standpipe pressure. The model of rotary drilling dynamics presented here provides a simple tool that describes the dynamic relationships between surface inputs block velocity, top drive velocity, and flow rate; and outputs...

Paper presented at the SPE/IADC International Drilling Conference and Exhibition, March 4–6, 2025
Paper Number: SPE-223695-MS
... Abstract This paper presents a study of three cases in which release of trapped torque occurs during the drill pipe connection process, leading to bottomhole assembly (BHA) damages. It highlights the contributing factors and root causes of the trapped torque release events, and it proposes...

Paper Number: SPE-217953-MS
..., over-torquing (uncontrolled down hole make-up) or, on the flipside, loosening of connections (reactive torque) is far too common and is intensified by the increase of laterals lengths. One cannot ignore our industry's extreme drive on operation efficiency and cost reduction. Unfortunately, ignoring...
