Another discovery has been made offshore Mauritania by Kosmos Energy.
The US independent made a gas discovery with the drilling of the
Marsouin-1 exploration well in the northern portion of Block C-8 using
the Atwood Achiever drillship.
Kosmos said that the discovery, its second major discovery in 2015, was a “significant, play-extending gas discovery”.
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 km north of the basin-opening
Tortue-1 gas discovery (renamed Ahmeyim), Marsouin-1 was drilled in
nearly 2,400 meters of water.
“Marsouin-1 is our second major
discovery of 2015, extending our 100% 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 CEO.
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.
