To optimize resourcerecovery in this field, we entered into the Unitization and Unit Operating Agreement (the JubileeUUOA) in July 2009 with the Ghana National Petroleum Corporation (GNPC) and the other blockpartners of each of these two blocks. The Jubilee UUOA governs the interests in and development ofthe Jubilee Field and created the Jubilee Unit from portions of the WCTP petroleum contract and theDT petroleum contract areas.These interest percentages are subject to redetermination of the participating interests in the JubileeField pursuant to the terms of the Jubilee UUOA. Our paying interest on development activities in theJubilee Field is 26.9%.(3) The Greater Tortue Ahmeyim Unit, which includes the Ahmeyim discovery in Mauritania Block C8 andthe Guembeul discovery in the Senegal Saint Louis Offshore Profond Block, straddles the borderbetween Mauritania and Senegal. To optimize resource recovery in this field, we entered into aUnitization and Unit Operating Agreement (GTA UUOA) in February 2019 with the governments ofMauritania and Senegal. The GTA UUOA governs interests in and development of the Greater Tortue14'
