On 1 July 2019 partner Kosmos announced that the GTA-1 appraisal well, GTA block, deep waters of the MSGBC Basin, found gas. The well intersected 30 m of net gas pay in high quality Albian reservoir. The well reached a total depth of 4,884 m and will be completed as a gas producer for the GTA floating LNG project which is currently under construction. The âEnsco DS-12â rig will now move to drill the Yakaar 2 appraisal well.   Available information suggests that BP is batch drilling the three following wells: Orca 1 in clock C-8, Yakaar 2 in Cayar Profond block and GTA-1 in GTA block.  The GTA-1 appraisal well was spudded around 14 May 2019 with the âEnsco DS-12â drillship coming from the Yakaar 2 well in Senegal where the top hole section was drilled. As of 14 June, the rig was still operating on the GTA-1 location.  As of 4 April 2019, the âEnsco DS-12â had entered Mauritanian waters in preparation for BPâs drilling campaign in Senegal and Mauritania. In late October 2018 industry sources announced that BP contracted the âEnsco DS-12â for two firm wells plus four one well option starting in April 2019 offshore Senegal. This rig has carried out the BP/Kosmos drilling campaign of 2017 when Yakaar was discovered. According to industry sources, the 2019 drilling campaign will include an exploration well in Mauritania (Orca) an appraisal well in Senegal (Yakaar) and an appraisal well in the cross-border GTA block. The latter, GTA-1, will target the eastern part of the Tortue / Ahmeyim field in the GTA block, deep waters of the MSGBC Basin.    In April 2015, Kosmos announced that the Tortue 1 new field wildcat well discovered gas. Based on intermediate logging to a depth of 4,630 m, the well has intersected 107 m of net hydrocarbon pay. In the primary Lower Cenomanian objective, a single gas pool, was encountered in three multi-Darcy permeability reservoirs totaling 88 m of net pay within a 160 m gross hydrocarbon bearing interval. In the secondary Upper Cenomanian objective, a 19 m net gas pay interval was intersected within a 150 m gross hydrocarbon bearing interval.    In its early May 2015 first quarter operations report, Kosmos gave further details about the Tortue West structure recently drilled with the Tortue 1 well. The porosity of the drilled reservoir portion ranges between 20 and 30% confirming good reservoir properties. The reservoir fluid is considered to be a fairly dry gas with a low condensate to gas ratio. Kosmos later reported that Tortue 1 found additional hydrocarbons in the deeper Albian secondary objective. The well intersected 10 m of net hydrocarbon pay in the Lower Albian section, which is currently interpreted to be gas. Kosmos chief exploration officer, Brian Maxted, commented: âThis suggests we have a working hydrocarbon system in both the Albian and Cenomanian sequences. While the Albian was not the primary objective of the Tortue 1 well, the presence of additional hydrocarbons in the Albian further de-risks other prospects in the Greater Tortue Complex which include primary reservoir targets in both the Albian and underlying Aptian.â    Participants in the unitized GTA block are BP, Kosmos, Petrosen and SMHPM. The split is believed to be BP (operator) 46%, Kosmos 14%, Kosmos Energy Investments Senegal 30%, SMHPM 5% and Petrosen 5%.
