Success was the result of applying the company’s proprietary knowledge of the Upper Cretaceous structural-stratigraphic play concept to the unique conditions of this region in which sands bypassed the shelf and deposited in deeper water. With major gas discoveries announced in 2016 at Guembeul-1 and Teranga-1, Kosmos has now drilled five consecutive successful exploration and appraisal wells offshore Mauritania and Senegal for a 100 percent success rate. In the process, we have discovered a gross Pmean resource of approximately 25 Tcf and estimate the in-board fairway may hold much more. Early in 2016, Kosmos entered into a Memorandum of Understanding (MOU) signed by Societé des Petroles du Sénégal (Petrosen) and Société Mauritanienne Des Hydrocarbures et de Patrimoine Minier (SMHPM), the national oil companies of Senegal and Mauritania, respectively, which sets out the principles for an intergovernmental cooperation agreement for the development of the cross-border Tortue field. The MOU enables Kosmos and the two governments to work together toward early development of the field, thereby maximizing value for all stakeholders. WORLD-CLASS BASIN WITH MULTI-BILLION BARREL POTENTIAL The Mauritania-Senegal basin, which Kosmos opened in 2015 and continues to explore, is potentially the largest new petroleum system on the Atlantic Margin, offering a combination of substantial discovered resource, as well as significant de-risked exploration upside. Kosmos currently estimates the total resource potential of the basin could be greater than 25 billion barrels of oil equivalent (BBoe) gross. Kosmos is currently maturing and ranking its prospect inventory with the expectation that we will test four independent prospects offshore Mauritania and Senegal during 2017 and 2018. These four wells – two in Mauritania and two in Senegal – will test approximately 10 to 15 billion barrels of oil equivalent of unrisked, gross potential. We believe they are some of the largest prospects to be drilled by the industry anywhere in the world in the next 18 months.
