 Ranger-1 well encounters approx. 230 feet of high-quality, oil-bearing reservoir Well is located approx. 60 miles northwest of Liza phase one project Discovery provides a new play concept for the 6.6 million acre Stabroek Block Exxon Mobil announced Friday positive results from its Ranger-1 exploration well, marking ExxonMobilâs sixth oil discovery offshore Guyana since 2015. 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. ExxonMobil affiliate Esso Exploration and Production Guyana began drilling the Ranger-1 well on Nov. 5, 2017 and encountered approx. 230 feet (70 meters) of high-quality, 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. 'This latest success operating in Guyanaâs 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.'The Ranger-1 discovery is located approx. 60 miles northwest of the Liza phase one project in the 6.6 million acre Stabroek Block 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 kms). Esso Exploration and Production Guyana is operator and holds 45 percent interest in the Stabroek Block. Hess Guyana Exploration holds 30 percent interest and CNOOC Nexen Petroleum Guyana holds 25 percent interest. Original article link Source: ExxonMobil 
Ranger 1 op. by ExxonMobil (45%, Hess 30%, CEO 25%), located ~60 miles NW of the Liza discovery, in the Stabroek block, encountered ~70m of high-quality, oil-bearing carbonate reservoir. The well tested a new play concept that targeted a feature HES officials described as âa large four-way structure that is different geologically than the stratigraphic traps that have been drilled thus far on the blockâ and is the first discovery on the block made in a carbonate interval. Previous discoveries were stratigraphically trapped (typically higher risk than a four-way closure) sandstone reservoirs.
