ExxonMobil discovers sixth oil field offshore Guyana

ExxonMobil and its partners have achieved a sixth oil discovery in the deepwater Stabroek block offshore Guyana.


The drillship Stena Carron spudded the Ranger-1 well in early November in 8,973 feet (2,735 metres) of water. The well intersected around 230 feet (70 metres) of good-quality, oil-bearing carbonate reservoir, and reached a subsurface depth of 21,161 feet (6,450 metres).


ExxonMobil estimates resources from this and the earlier Liza, Payara, Snoek, Liza Deep, and Turbot finds at more than 3.2 Bboe.


“This latest success operating in Guyana’s significant water depths illustrates our ultra-deepwater and carbonate exploration capabilities,” said Steve Greenlee, president of ExxonMobil Exploration Company. “This discovery proves a new play concept for the…Stabroek block, and adds further value to our growing Guyana portfolio.”


Following completion of Ranger-1 well, the Stena Carron will transfer to drill the Pacora prospect, four miles (6.4 kilometres) from the Payara discovery. The partners plan further exploration drilling on the block later this year, including potential appraisal work at Ranger.


The Stabroek block covers 6.6 million acres (26,800 square kilometres). Esso Exploration and Production Guyana Ltd is operator, in partnership with Hess Guyana Exploration and CNOOC Nexen Petroleum Guyana.
