KOSMOS ENERGY LTD. Notes to Consolidated Financial Statements (Continued) 6. Suspended Well Costs (Continued) determination regarding commerciality of the discovery. If we determine the discovery to be commercial, a declaration of commerciality would be provided and a PoD would be prepared and submitted to Ghana’s Ministry of Energy, as required under the WCTP petroleum contract. Wawa Discovery—In February 2016, we requested the Ghana Ministry of Energy to approve the enlargement of the areal extent of the TEN fields and production area to capture the resource accumulation located in the Wawa Discovery Area for a potential future integrated development with the TEN fields. In April 2016, the Ghana Ministry of Energy approved our request to enlarge the TEN development and production area subject to continued subsurface and development concept evaluation, along with the requirement to integrate the Wawa Discovery into the TEN PoD. We are currently in discussions with the Ministry of Energy with respect to conducting further subsurface and development concept evaluation. Greater Tortue Discovery—In May 2015, we completed the Tortue-1 exploration well in Block C8 offshore Mauritania which encountered hydrocarbon pay. Two additional wells have been drilled in the Greater Tortue Discovery area, Ahmeyim-2 in Mauritania and Guembeul-1 in Senegal. We completed a drill stem test on the Tortue-1 well in August 2017, which confirmed the production capabilities of the Greater Tortue Discovery. Data acquired from the drill stem test is being used to further optimize field development and to refine process design parameters critical to the Front End Engineering Design (FEED) process. Following additional evaluation, a decision regarding commerciality will be made. BirAllah Discovery—In November 2015, we completed the Marsouin-1 exploration well (renamed BirAllah) in the northern part of Block C8 offshore Mauritania which encountered hydrocarbon pay. Following additional evaluation, a decision regarding commerciality will be made. Teranga Discovery—In May 2016, we completed the Teranga-1 exploration well in the Cayar Offshore Profond block offshore Senegal which encountered hydrocarbon pay. Following additional evaluation, a decision regarding commerciality will be made. 7. Equity Method Investments Kosmos BP Senegal Limited As part of our transaction in Senegal with BP, our petroleum contracts in Senegal were contributed to KBSL, a corporate joint venture in which we owned a 50.01% interest. The objective of this transaction was to accelerate the development of discovered gas resources, ensure the execution of an appropriately sized exploration program and reduce the Company’s capital spending requirements for exploration and development over the near to medium term. In October 2017, upon approval, KBSL transferred a 30% working interest in the Senegal Blocks to BP Senegal Investments Limited in exchange for their outstanding shares of KBSL. As a result, KBSL became a wholly-owned subsidiary of Kosmos, and will no longer be accounted for under the equity method of accounting. After the transfer, KBSL has a 30% working interest in the Senegal Blocks. Prior to the acquisition of the remaining outstanding shares of KBSL in October 2017, our investment in KBSL qualified for the equity method of accounting. Our initial contribution to KBSL was $133.9 million, which was recorded at our carrying costs. Our share of the KBSL operations during the period it was accounted for as an equity method investment is reflected in our consolidated 125
