Kosmos Energy said a “significant” discovery has been made at the Marsouin-1 exploration well offshore Mauritania.
The well, located in the northern part of Block C-8, is the company’s second major discovery of the year.
The Marsouin-1 well encountered 70metres of net gas pay in the Upper and Lower Cenomanian intervals comprised of excellent quality reservoir sands.
Andrew Inglis, chief executive, said:“Marsouin-1 is our second major discovery of 2015, extending our 100 percent 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.”
Kosmos Energy said 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.
