  • Ranger-1 well encounters approximately 230 ft of high-quality, oil-bearing reservoir.
  • Well is located approximately 60 miles northwest of Liza phase one project.
  • Discovery provides a new play concept for the 6.6 million acre Stabroek Block.

Exxon Mobil Corporation announced on 5 January positive results from its Ranger-1 exploration well, marking ExxonMobil’s sixth oil discovery offshore Guyana since 2015.

The Ranger-1 well discovery adds to previous discoveries at Liza, Payara, Snoek, Liza Deep and Turbot, which are estimated to total more than 3.2 billion recoverable oil-equivalent barrels.

ExxonMobil affiliate Esso Exploration and Production Guyana Ltd. began drilling the Ranger-1 well on Nov. 5, 2017 and encountered approximately 230 ft (70 m) of high-quality, oil-bearing carbonate reservoir. The well was safely drilled to 21 161 ft (6450 m) depth in 8973 ft (2735 m) of water.

“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 6.6 million acre Stabroek Block, and adds further value to our growing Guyana portfolio.”

Following completion of the Ranger-1 well, the Stena Carron drillship will move to the Pacora prospect, 4 miles from the Payara discovery. Additional exploration drilling is planned on the Stabroek Block for 2018, including potential appraisal drilling at the Ranger discovery.

The Stabroek Block is 6.6 million acres (26 800 sq. km). Esso Exploration and Production Guyana Ltd. is operator and holds 45% interest in the Stabroek Block. Hess Guyana Exploration Ltd. holds 30% interest and CNOOC Nexen Petroleum Guyana Limited holds 25% interest.
