b'In February 2016, the Jubilee Field operator identified an issue with the turret bearing of theFPSO Kwame Nkrumah. Kosmos and its partners completed the lifting and locking of the main turretbearing, and the rotation of the vessel to its final heading in the second half of 2018. Permanent spreadmooring of the vessel is expected to be completed around mid-year 2019.The financial impact of lower Jubilee production as well as the additional expenditures associatedwith the damage to the turret bearing is mitigated through a combination of the comprehensive Hulland Machinery insurance (H&M), procured by the operator, Tullow, on behalf of the Jubilee Unitpartners, and the corporate Loss of Production Income (LOPI) insurance procured by Kosmos. OurLOPI coverage for this incident ended in May 2017 and the final cash proceeds were received inAugust 2017. Oil production from the Jubilee Field averaged approximately 78,000 Bopd gross (18,800Bopd net) during 2018.Tweneboa, Enyenra and Ntomme (TEN)The TEN fields are located in the western and central portions of the DT Block, approximately48 kilometers offshore Ghana in water depths of approximately 1,000 to 1,700 meters. In November2012, we submitted a declaration of commerciality and PoD over the TEN discoveries, and in May2013, the government of Ghana approved the TEN PoD. The discoveries are being jointly developedwith shared infrastructure and a single FPSO, the Professor John Evans Atta Mills.Similar to Jubilee, the TEN fields are being developed in a phased manner. The TEN PoD wasdesigned to include an expandable subsea system that would provide for multiple phases. Phase 1 ofthe TEN PoD includes the drilling and completion of up to 17 wells, 13 of which have been completed.Seven additional development wells are expected to be drilled during Phase 2. The remaining Phase 1and Phase 2 wells are a combination of production wells and water or gas injection wells needed tomaximize recovery.First oil from the TEN fields was produced in August 2016. In January 2017, the capacity of theFPSO was successfully tested at an average rate of 80,000 Bopd during a short-term flow test. InSeptember 2017, International Tribunal of the Sea issued its final decision in the previously disclosedmaritime boundary dispute between the Governments of Ghana and Cote dIvoire, which alloweddrilling to resume in early 2018. These additional wells are expected to increase production towardsFPSO capacity. Production from TEN in the year ended December 31, 2018 averaged approximately64,500 Bopd gross (10,400 Bopd net).The construction and connection of a gas pipeline between the Jubilee and TEN fields to transportnatural gas to the mainland for processing and sale was completed in the first quarter of 2017. InDecember 2017, we signed the TEN Associated-GasGas Sales Agreement (TAG GSA) and wecommenced exporting gas to shore in the fourth quarter of 2018. However, the uptime of the gasprocessing facility in future periods is unknown. Our inability to continuously export associated naturalgas in large quantities from the TEN fields could impact our oil production.U.S. Gulf of MexicoIn September 2018, as part of the DGE transaction, Kosmos acquired: (i) a portfolio of producingassets that Kosmos can continue to exploit, (ii) infrastructure-led exploration growth assets, and (iii) ahigh-quality inventory of exploration prospects across the East Breaks, Garden Banks, Green Canyonand Mississippi Canyon areas. Our U.S. Gulf of Mexico assets averaged approximately 23,700 Boepd(net) (~81% oil) from twelve fields from the acquisition date through the end of 2018. We expandedour inventory through the U.S. Gulf of Mexico Lease Sale 251 in which we were awarded seven newdeepwater blocks.The following is a brief discussion of our key producing fields in the U.S. Gulf of Mexico.17'
