Continuous-Circulation Technique Drills Narrow-Margin Deepwater Wells


Ultradeepwater wells are commonly characterized by their narrow margins between pore and fracture gradients. In these wells, even a small variation in pressure profile may lead to severe operational issues. Read the full article from JPT describing the Continuous-Circulation Technique in Deepwater Wells:

MPD and continuous circulation technology overcome deepwater challenges


Wells drilled offshore Sabah, East Malaysia, using conventional open wellbore technology, have experienced well control events and significant NPT. Problems encountered included kicks, stuck pipe, and lost mud circulation.
