SPE J. 26 (03): 1092–1109.
Paper Number: SPE-204209-PA
Published: 16 June 2021
... weight generates a hydrostatic pressure that serves as a counterpressure to the displacement of the salt. Sometimes this measure is not enough, leading to the backreaming operation, which reconditions the diameter of the wellbore to its original state. Given the importance of backreaming during drilling...

Paper Number: SPE-174797-MS
... Abstract One of the major challenges recently encountered is vibration of the drillstring under backreaming condition (simultaneous pumping, rotating, and pulling out of the hole). Traditionally, much attention is focused on predicting vibration and measurements under normal drilling operations...
