..., and the application of advanced drilling optimization techniques. In the offshore fields under study, the top section typically involves drilling through formations at a range of depths with moderate inclinations. Despite the relatively straightforward technological requirements, such as using motor BHA...

Digital twin using playback data from a well, offshore Mid-Norway has been carried out with automated correction...

... deceleration rate). Other risk factors include poor damping of the generated fastline vibrations and high fastline inclination (deviation from vertical). Even though inherent bending resistance of the wire rope is a significant damping mechanism for high-frequency vibrations, it is very weak for low-frequency...

... of extended-reach wells may become technically very challenging, as these wells often have long sections drilled at high inclinations that can be prone to borehole instability problems such as pack-offs or collapse of the wellbore wall. The case of an extended-reach well drilled in the Ekofisk field...

Selection of Bullheading Fluid Experimental Facility and Test Matrix To understand the influences of fluid properties, wellbore inclinations, and drill pipe rotation on managing...

... pipe and a 4-in O.D. inner pipe oriented eccentrically. The RTS overall fluid column height was 11.45-ft. The eccentric inner pipe was designed to rotate at up to 100 rpm to mimic the eccentric drilling string used in a typical drilling operation. An inclinable test frame was used to secure the RTS...
