Multiphase flow simulations have been carried out where varying combinations of pill type, cuttings diameter, and inner pipe rotation were tested...

... are straightforward, as the limiting case is a full rotation at a 1 degree/100ft build. The concerning case for a drilling engineer is what recovery is still possible in the lowest observed curvature case. Assuming the recovery operations are attempted with a full slide (R s = 1) targeting a 90% tool face accuracy...

... of drilling data. The drilling data used in this research is from the Volve oil field in Stavanger, Norway. The preprocessed data consisted of pump pressure, surface torque average, rotation per minute of drill bit, mudflow rate, total gas content, effective circulation density, pump stroke rate, lithology...

... applications, slack-off of an air-filled casing string (string "floatation") is followed by the insertion of a "floatation sub" to augment uphole weight near TD, and rotation is used as a contingency measure. An increasing number of operators completing plug and perf unconventional wells are also rotating...

The RTS is 10-ft long, having a 6 inch × 4 inch eccentric annular geometry with the inner pipe capable of rotation. The inclination of all test sections...

.... One way to enhance cleanout efficiency is by rotating the drill pipe to mitigate the settling of solids and facilitate their removal. However, drill string rotation often increases equivalent circulating density (ECD). Therefore, this study explores how the impact of rotation on hole cleaning can...

Abstract Results from a long-term field study to improve zonal isolation show that rotating production casing in unconventional well laterals is possible and that it delivers excellent cement quality. This paper reports the results of the study. To date, 44 production strings have been rotated...

The tool has an irreversible locking device, which can be activated during drill out by setting BHA weight on the top assembly, to prevent rotation of the reamer shoe if the cementation has been problematic or unsuccessful...

... Abstract It has long been recognized that the movement of casing can improve cement jobs and assist in running casing in challenging well trajectories. Both reciprocation and rotation of casing relies upon the use of the rig at the surface to rotate or reciprocate the entire casing string...
