b'an area of approximately 5.9 million acres (gross) in water depths ranging from 2,250 to 3,000 metersand provide an opportunity to pursue the same core Cretaceous theme that was successful for us inGhana.Our blocks are adjacent to, and represent an extension of, a proven and prolific petroleum systemoffshore Equatorial Guinea and northern Gabon comprising Early Cretaceous post-rift source rocksand Late Cretaceous reservoirs. Kosmos has established an extensive position in the Rio Muni Basinwhere there is a proven source and reservoir inboard with the Ceiba and Okume discoveries inEquatorial Guinea, which appears to extend outboard into the deepwater in Sao Tome and Principe,where there are oil seeps on both islands. Kosmos has identified large potential structural andstratigraphic traps on early seismic, which is currently being processed.We believe that the southern extent of the West African transform margin in Sao Tome andPrincipe comprises a series of Albian pull-apart basins formed during the separation of Africa fromSouth America, providing the necessary conditions for the generation, migration and entrapment ofhydrocarbons. Large sandstone depo-centers were developed at the structural junctions of rift and shearfault trends resulting in the deposition of deep-water slope channels and basin floor fans draping overand around anticlinal highs adjacent to fracture zones. These constitute the main play in the acreage.In December 2016, we received approval for a two-year extension of Phase 1 for Block 5 offshoreSao Tome and Principe, which now expires in May 2019. Additionally, during the same month weassigned 20% participating interest to Galp in each of Blocks 5, 11 and 12 offshore Sao Tome andPrincipe. Based on the terms of the agreement, Galp has paid a proportionate share of Kosmos pastcosts in the form of a partial carry on the 3D seismic survey.In August 2017, we completed a 3D seismic survey of approximately 15,800 square kilometers overBlocks 5, 6, 11, and 12 offshore Sao Tome and Principe. Processing has been completed. We arecompiling an inventory of prospects on the license areas in Sao Tome and Principe and will continue torefine and assess the prospectivity, integrating this new 3D seismic data into our geological evaluationduring 2019 with a view to drilling as early as 2020.In November 2017, we received approval for a one-year extension of Phase 1 for Block 11 offshoreSao Tome and Principe, which now expires in July 2019.MoroccoIn August 2018, we provided to the Office National Des Hydrocarbures et des Mines (ONHYM)a notice to abandon the Essaouira Offshore block, located offshore Morocco, at the end of the thencurrent exploration phase (November 2018).Cote dIvoireIn December 2017, as part of our Alliance with BP, we entered into petroleum contracts asoperator for five Offshore Blocks, CI-526, CI-602, CI-603, CI-707 and CI-708, which are located in aCenomanian-Turonian petroleum system and range in water depth from 450 to 4,500 meters. The areais located approximately 150 kilometers west of our TEN discoveries in Ghana. We believe the area hasmultiple Cretaceous source rocks with Cenomanian through Maastrichtian reservoir sands providingexploration targets. In May 2018, we completed a 3D seismic survey covering approximately 12,000square kilometers over blocks CI-526, CI-602, CI-603, CI-707 and CI-708 offshore Cote dIvoire.23'
