DALLAS, TX – Kosmos Energy has announced that the Marsouin-1 exploration well, located in the northern part of Block C-8 offshore Mauritania, has made a significant, play-extending gas discovery. 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 meters (230 feet) of net gas pay in Upper and Lower Cenomanian intervals comprised of excellent quality reservoir sands.

Located approximately 60 kilometers north of the basin-opening Tortue-1 gas discovery (renamed Ahmeyim), Marsouin-1 was drilled in nearly 2,400 meters of water.

The Islamic Republic of Mauritania, is a country in the Maghreb region of western North Africa, bordered by the Atlantic Ocean to the west, Moroccan-controlled Western Sahara in the north, Algeria in the northeast, Mali in the east and southeast, and Senegal in the southwest.

“Marsouin-1 is our second major discovery of 2015, extending our 100 per cent success rate in the outboard Cretaceous petroleum system offshore Mauritania and Senegal. Well-to-seismic calibration has significantly de-risked the discovered resource base, as well as future prospects in the basin.”

“Importantly, the well results have validated our charge model and given us growing confidence in our ability to predict the oil and gas potential of this emerging, large-scale petroleum system. We have a disciplined exploration and appraisal program planned to further unlock the basin,” said Andrew G. Inglis, chairman and chief executive officer.

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.
