Kosmos Energy said Sept. 23 the Yakaar-2 appraisal well has encountered about 30 m of net gas pay in similar high-quality Cenomanian reservoir to the Yakaar-1 exploration well, continuing the 100% success rate of wells targeting the inboard Mauritania/Senegal gas trend.

Yakaar-2 was drilled about 9 km from Yakaar-1 and proved up the southern extension of the field.

The results of the Yakaar-2 well underpin Kosmos Energy’s view that the Yakaar-Teranga resource base is world-scale and has the potential to support an LNG project that provides significant volumes of natural gas to both domestic and export markets. Development of Yakaar-Teranga is expected in a phased approach with Phase 1 providing domestic gas and data to optimize the development of future phases. It will also support the country’s “Plan Emergent Senegal” launched by the President of Senegal in 2014.

Commenting on the results of the Yakaar-2 well, Chairman and CEO Andrew G. Inglis said: “The Yakaar-2 appraisal well demonstrates the scale and quality of the Yakaar resource base. Senegal is one of the fastest growing economies in the world and Kosmos is excited to be working alongside BP and Petrosen to support the country’s growing energy needs.”

Located offshore Senegal, the Yakaar-2 well was drilled in about 2,500 m of water to a total measured depth of around 4,800 m.

The Valaris DS-12 rig, working on behalf of the operator BP, will now move to the Orca-1 exploration well in Mauritania.

Partners in the Yakaar-Teranga gas project, located offshore Senegal, include Petrosen, BP, and Kosmos.
