ExxonMobil continues on its discovery spree in the Stabroek block, N-C part of offshore Guyana Basin, 70m of high-quality, oil-bearing carbonates encountered, TD 6,450m, Stena Carron DS. Location is ab. 100km NW of the Liza field in WD 2,735m. Ranger follows the Liza, Payara, Snoek, Liza Deep, and Turbot finds, gross recoverable resource estimates >3.2 Bboe so far within the block (excluding Ranger).  Next well Pacora-1 ab. 6.5km from Payara. ExxonMobil (op), partners Hess + CNOOC-Nexen.
Ranger 1 op. by ExxonMobil (45%, HES 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.
