ESP deployed via riser to lift subsea well

摘要

The No.1 well in East Breaks Block 690 is a 41/2-mi subsea tieback to Ana-darko's Nansen spar in the Western Gulf of Mexico.The well produced 1.7 million bbl oil before pressure depletion caused slugging and frequent liquid loading in the riser and the subsea flowline network.Loading of the riser occurred at a 5-10% watercut,leaving significant reserves in the ground.As such,a viable form of artificial lift was needed.
