S-well profile, batch drilling, LWD systems push performance on TuIIow's fast-tracked Jubilee

摘要

TULLOW OIL HAS INTERESTS in two exploration licences offshore Ghana where two successful exploration wells, Mahogany-1 and Hyedua-1, discovered the substantial Tullow-operated Jubilee field in mid-2007. The field straddles the boundary between the two blocks -Deepwater Tano and West Cape Three Points. Results from three accelerated appraisal wells drilled during 2008 - Mahogany-2, Hyedua-2 and Mahogany-3 - showed that the Jubilee field was a continuous strati-graphic trap with a potential resource upside of 1.8 billion bbl. A fast-track development was embarked upon thereafter.
