StockMarketWire.com - Kosmos Energy said the Orca-1 exploration well drilled in a venture with BP had made a 'major' gas discovery offshore Mauritania.

The Orca-1 well, which targeted a previously untested Albian play, exceeded pre-drill expectations encountering 36 meters of net gas pay in 'excellent' quality reservoirs, Kosmos said.

The location of Orca-1, approximately 7.5 kilometers from the crest of the anticline, proved both the structural and stratigraphic trap of the Orca prospect, which 'we estimate has a mean gas initially in place of 13 trillion cubic feet,' the company said.

'In total, we believe that Orca-1 and Marsouin-1 have de-risked up to 50 TCF of GIIP from the Cenomanian and Albian plays in the BirAllah area, more than sufficient resource to support a world-scale LNG project,' it added. Story provided by StockMarketWire.com
