17 March 2016 — Kosmos Energy announced Wednesday that its Ahmeyim-2 appraisal well has successfully delineated the Ahmeyim and Guembeul gas discoveries offshore Mauritania and Senegal, encountering 256 feet of net gas pay in two “excellent quality reservoirs” in the process.
Located in Mauritanian waters approximately 3 miles northwest of the basin-opening Tortue-1 discovery well in approximately 9,200 feet of water, Ahmeyim-2 was drilled to a total depth of 17,060 feet. The well has extended the productive field area from approximately 19 square miles to 34 square miles and confirmed static fluid pressure communication between the Tortue-1, Guembeul-1 and Ahmeyim-2 wells within the Lower Cenomanian.
With the integration of the Ahmeyim-2 well results, Kosmos’ gross resource estimate for the Tortue West structure has increased to 15 trillion cubic feet of gas from 11 Tcf. The gross resource estimate for the Greater Tortue Complex has increased to over 20 Tcf from 17 Tcf.
Commenting on the latest development, Andrew G. Inglis, chairman and chief executive officer of Kosmos Energy, said in a company statement:
“Ahmeyim-2 is our fourth successful exploration and appraisal well and continues our 100 percent success rate in the outboard Cretaceous petroleum system offshore Mauritania and Senegal, further demonstrating that Kosmos has opened a world-class hydrocarbon province. With this well, we believe we have proven sufficient gas resource to underpin a world-scale LNG project in the Tortue West structure alone. The combination of the resource size and quality continue to support our view that Tortue is a competitive source of LNG and we are working towards commercialization.
“Our well-to-seismic calibration has again been proven, highlighting the reliability of this tool and increasing our confidence in its use for fully unlocking the basin, which we believe has significant potential for both oil and gas. We now plan to drill the first of three independent oil tests in our blocks offshore Mauritania and Senegal, starting with the Teranga-1 well, located in the Cayar Offshore Profond Block, offshore Senegal.”
Kosmos operates the Ahmeyim-2 well with 90 percent equity and is joined by its partner SMHPM at 10 percent.
