Kosmos Energy has announced a gas discovery with the Orca-1 exploration well in the BirAllah area offshore Mauritania. Kosmos said Orca and the earlier Marsouin-1 well had de-risked enough gas to support a third LNG hub in addition to Greater Tortue Ahmeyim (GTA) and Yakaar. Wood Mackenzie said Orca was the third-largest discovery worldwide so far this year and the largest deep-water find. The well was drilled 125km offshore in 2,510 metres of water to a total depth of around 5,266 metres in the same fairway as the GTA and Yakaar gas discoveries.
