... for kick circulation, such as Influx Management Envelope (IME) and the MPD matrix, there is still a literature gap regarding kick management with the bit off bottom - a common scenario during tripping, reaming, mud displacement, or running liners. The identification and control of a kick with the bit off...

..., such as losses, ballooning, and wellbore instability. MPD was selected as an enabler for overcoming these challenges. The sidetrack was planned to exit the existing 14-inch casing and run three additional strings of casing/liners to a planned total depth (TD) over 31,000 ft MD. MPD was strategically integrated...

... exploration and appraisal campaign was planned for late summer 2016. The first well was a re-entry of a previously suspended exploration well from the year before. This well had been suspended with a 7″ liner set above an expected karstified carbonate formation. Prior to sailing, the rig and marine riser were...

The liner was then conveyed to bottom conventionally which resulted in lost circulation during breaking the gel of this high mud at high pressures...
