BP has said its recent three-well drilling campaign offshore Mauritania and Senegal “has further confirmed the world-class scale of the gas resource in the region”. Three appraisal wells drilled this year, GTA-1, Yakaar-2 and Orca-1, encountered gas in high-quality reservoirs in all nine hydrocarbon-bearing zones targeted. The wells, the first to be operated by BP after it took over as operator from Kosmos Energy, encountered 160 metres of total gas pay.
