Exxon Mobil Corporation (ticker: XOM) has discovered its sixth oil reservoir in offshore Guyana since 2015, resulting from the Ranger-1 exploration well.
The Ranger-1 well discovery adds to previous world-class discoveries at Liza, Payara, Snoek, Liza Deep and Turbot, which are estimated to total more than 3.2 billion recoverable oil-equivalent barrels, according to Exxon.
Exxon said that additional exploration drilling is planned on the Stabroek Block for 2018, including potential appraisal drilling at the Ranger discovery.
ExxonMobil affiliate Esso Exploration and Production Guyana Ltd. began drilling the Ranger-1 well on Nov. 5, 2017 and encountered approximately 230 feet (70 meters) of oil-bearing carbonate reservoir. The well was safely drilled to 21,161 feet (6,450 meters) depth in 8,973 feet (2,735 meters) of water.
Steve Greenlee, president of ExxonMobil Exploration Company stated the success “illustrates our ultra deepwater and carbonate exploration capabilities,” adding that “this discovery proves a new play concept for the 6.6 million acre Stabroek Block.”
Esso Exploration and Production Guyana Limited together hold a 45 percent interest in the Stabroek Block. Hess Guyana Exploration Ltd. holds a 30 percent interest and CNOOC Nexen Petroleum Guyana Limited holds a 25 percent interest.
