The Marsouin-1 exploration well, located in the northern part of Block C-8 offshore Mauritania, has made a significant, play-extending gas discovery, Kosmos Energy (NYSE: KOS) said. This is the company’s second major discovery of 2015.
Based on preliminary analysis of drilling and wireline logging results, Marsouin-1 encountered at least 70 m (230 ft) of net gas pay in Upper and Lower Cenomanian intervals comprised of excellent quality reservoir sands. Located about 60 km north of the basin-opening Tortue-1 gas discovery (renamed Ahmeyim), Marsouin-1 was drilled in nearly 2,400 m of water.
The Atwood Achiever drillship will now proceed to the Ahmeyim-2 location in the southern part of Mauritania’s Block C-8 where it will drill the top-hole section of the well. The drillship is then expected to sail to Senegal where it will spud Guembeul-1, the first in a series of wells to delineate the Greater Tortue area, before year-end.
