With a series of successful exploration and appraisal wells on the West Tortue structure, we have discovered a significant amount of natural gas and believe we have opened one of the largest new petroleum systems anywhere in the world over the last 15 years. Given better- than-expected results and growing confidence in our understanding of the basin, we believe we have de-risked sufficient resource to underpin a world-scale LNG project. Kosmos is now working toward commercialization by developing a project concept that delivers competitive gas in the current market environment. In addition, we are facilitating an intergovernmental cooperation agreement between Mauritania and Senegal to enable early development of the cross-border Tortue field. In early 2016, we entered into a Memorandum of Understanding (MOU) with Société des Pétroles du Sénégal (Petrosen) and Société Mauritanienne Des Hydrocarbures et de Patrimoine Minier (SMHPM), the national oil companies of Senegal and Mauritania, which sets out the principles on which a formal agreement will be based. Beyond commercializing Tortue, our focus in Mauritania and Senegal remains on fully unlocking this new and promising hydrocarbon province. Based on our well results and seismic data, we believe the basin has potential for both significant gas and oil resources.
