b'encountered 78 meters of net gas pay in two excellent quality reservoirs, including 46 meters in theLower Cenomanian and 32 meters in the underlying Albian.In August 2017, we completed the drill stem test (DST) of the Tortue-1 well, demonstrating thatthe Tortue field is a world-class resource and confirming key development parameters including welldeliverability, reservoir connectivity, and fluid composition. The Tortue-1 well flowed at a sustained,equipment-constrained rate of approximately 60 MMcfd during the main extended flow period, withminimal pressure drawdown, providing confidence in well designs that are each capable of producingapproximately 200 MMcfd. The DST results confirmed a connected volume per well consistent with thecurrent development scheme, which together with the high well rate is expected to result in a lownumber of development wells compared to equivalent schemes. Initial analysis of fluid samplescollected during the test indicate Tortue gas is well suited for liquefaction given low levels of liquidsand minimal impurities. Data acquired from the DST was used to further optimize field developmentand to refine process design parameters critical to the front end engineering and design (FEED)process.In December 2018, the partners agreed on a final investment decision for Phase 1 of the GreaterTortue Ahmeyim project. The Greater Tortue Ahmeyim project is designed to produce gas from adeepwater subsea system to a mid-water FPSO and then to a FLNG facility at a nearshore hub locatedon the Mauritania and Senegal maritime border. The FLNG facility for Phase 1 is designed to produceapproximately 2.5 million tons per annum on average. The project will provide LNG for global export,as well as make gas available for domestic use in both Mauritania and Senegal. First gas for the projectis expected in the first half of 2022. Following a competitive tender process involving all partners andsubject to final documentation, BP Gas Marketing has been selected as the buyer for the LNG offtakefor Greater Tortue Ahmeyim Phase 1.Other Mauritania and Senegal DiscoveriesThe BirAllah discovery (formally known as Marsouin), located in Block C8 offshore Mauritania, isa significant, play-extending gas discovery, building on our successful exploration program in theoutboard Cretaceous petroleum system offshore Mauritania. The Marsouin-1 well is locatedapproximately 60 kilometers north of the Ahmeyim discovery and was drilled to a total depth of 5,150meters in nearly 2,400 meters of water. Based on analysis of drilling results and logging data,Marsouin-1 encountered at least 70 meters of net gas pay in Upper and Lower Cenomanian intervalscomprised of excellent quality reservoir sands.The Teranga discovery is located in the Cayar Offshore Profond block approximately 65 kilometersnorthwest of Dakar, and was our second exploration well offshore Senegal. The Teranga-1 discoverywell is located in nearly 1,800 meters of water and was drilled to a total depth of approximately 4,850meters. The well encountered 31 meters of net gas pay in good quality reservoir in the LowerCenomanian objective. Well results confirm that a prolific inboard gas fairway extends approximately200 kilometers south from the Marsouin-1 well in Mauritania through the Greater Tortue Ahmeyimarea on the maritime boundary to the Teranga-1 well in Senegal.The Yakaar discovery is located in the Cayar Offshore Profond block offshore Senegal,approximately 95 kilometers northwest of Dakar in approximately 2,600 meters of water. The Yakaar-1discovery well was drilled to a total depth of approximately 4,900 meters. The well intersected a grosshydrocarbon column of 120 meters in three pools within the primary Lower Cenomanian objective andencountered 45 meters of net pay. An appraisal well is planned in 2019.Equatorial GuineaIn October 2017, we entered into petroleum contracts covering Blocks EG-21, S, and W with theRepublic of Equatorial Guinea. The petroleum contracts cover approximately 6,000 square kilometers,20'
