K osmos served as Technical Operator for development at Jubilee. The Jubilee Field development was designed in a phased approach to bring first production on quickly and to apply early findings to follow-on phases. First production came in late 2010, just three and a half years from the initial discovery, an industry- leading timeframe in deepwater developments. The success at Jubilee de-risked additional opportunities, and Kosmos and its partners have made a number of additional oil and gas-condensate discoveries. Kosmos and partners discovered the significant Tweneboa gas- condensate accumulation in 2009, followed by the Enyenra oil field in 2010. Further drilling success resulted in the discovery of oil at the Ntomme field in 2012. Production from Tweneboa, Enyenra, and Ntomme (TEN) began in 2016. Kosmos is now a non-operating co-venturer of the Jubilee Unit and the TEN fields, comprised of Tullow Oil, Anadarko Petroleum, PetroSA, and Ghana National Petroleum Company (GNPC). Tullow Oil is the operator of the Jubilee Unit and TEN fields, meaning it oversees operations related to oil and gas production. Although Kosmos does not oversee day-to-day operations of the Jubilee Unit and TEN fields, we take an active role in stakeholder engagement, secondment of top national talent, social investment programs, and other activities to help ensure Ghanaians receive benefits from hydrocarbon production. MANAGING OUR FOOTPRINT In 2018, gross volumes from the Jubilee and TEN fields averaged approximately 78,000 bopd and 64,500 bopd, respectively. The Jubilee and TEN fields also continue to supply natural gas to the Ghana National Gas Company’s onshore processing facility at Atuabo and onward flow to the Aboadze power plant for fuel to generate electricity. Kosmos continues to advocate for a national plan to expand Ghana’s gas infrastructure to meet the country’s domestic power needs in a cost efficient and sustainable way, which emphasizes domestic gas utilization first. Prioritizing Safety and the Environment Our active monitoring of safety and environmental compliance in Ghana contributed to strong HSE performance in 2018. There were no environmental incidents or Lost Time Incidents (LTIs) for any of Kosmos’ operations in Ghana in 2018, continuing our record of zero LTIs since 2012. We continued to invest in safety training throughout the year, which helped sustain performance gains achieved in prior years. Tullow Oil, as operator, reports on the safety and environmental performance for Jubilee and TEN operations. Our staff in Ghana receives behavioral safety training each year in addition to annual training on Kosmos’ Health, Safety, and Environment policies and standards. These trainings are mandatory. We believe they contribute to our strong safety record in Ghana. The FPSO John Evans Atta Mills produces oil at the Tweneboa, Enyenra, and Ntomme (TEN) fields. Kosmos opened a significant new hydrocarbon province, the Tano Basin, with the discovery of the Jubilee Field offshore Ghana in 2007. The Jubilee Field straddles both the West Cape Three Points and Deepwater Tano blocks. Success at Jubilee was the result of the company’s identification of a previously overlooked exploration play concept. 31 PRODUCTION OPTIMIZATION INFRASTRUCTURE- LED EXPLORATION DEVELOPMENT OF WORLD-SCALE DISCOVERIES BASIN-OPENING EXPLORATION Ghana JUBILEE WEST CAPE THREE POINTS BLOCK DEEPWATER TANO BLOCK Gulf of Guinea
