With interest in Mauritania revived by Kosmos Energy’s gas discoveries, ExxonMobil has signed production-sharing agreements (PSAs) for three vacant deep-water blocks. Blocks C22, C17 and C14 are located an average of 200km offshore. Together they measure nearly 34,000km2, in water depths ranging from 1,000 metres to more than 3,500 metres.The new licences follow a farm-in to Kosmos’ blocks by BP, announced in December 2016, while in May, Total signed a new PSA for Block C7, previously operated by Dana Petroleum.
