Kosmos Energy has announced a “significant, play-opening gas discovery” with the Tortue-1 exploration well in offshore Block C-8. The well, drilled in 2,700 metres of water to test the Tortue West prospect which forms part of the Greater Tortue Complex, intersected 107 metres of net hydrocarbon pay. A single gas pool was encountered in the primary Lower Cenomanian objective, comprised of three high-quality reservoirs totalling 88 metres in thickness over a gross hydrocarbon bearing interval of 161 metres.
