Major gas field discovery reported off Mauritania

Kosmos Energy’s Orca-1 exploration well has made a major gas discovery offshore Mauritania in the BirAllah area, the company has said, adding that it believed the find to be the largest deepwater hydrocarbon discovery in the world so far this year – more than sufficient resource to support a world-scale LNG project. Kosmos Energy also said that a deeper, untested play had also been identified in the area.

The find is located about 125km off Mauritania, drilled in 2,510 metres of water to a total measured depth of around 5,266 metres.

“Rystad Energy estimates Orca-1 holds around 1.3bn barrels of oil equivalent  of recoverable resources,” said Palzor Shenga, a senior analyst on Rystad Energy’s upstream team.

By way of comparison, Russia has 1.5bn boe so far this year, the most by any single country in the world this year.

The discovery lies in the MSGBC (Mauritania-Senegal-Gambia-Bissau-Conakry) basin.
