Kosmos Energy has encountered oil and gas at its Enyenra-2A appraisal well in the deepwater Tano block, offshore Ghana.
The Enyenra-2A well has oil and gas condensate in high quality stacked sandstone reservoirs.
The hydrocarbon presence at the well confirms a downdip extension of the light oilfield discovered by the Owo-1 (renamed Enyenra) exploration well, which was drilled in 2010.
The well, located 7km south and downdip of the Owo-1, was drilled to intersect the upper channel where oil was discovered and the lower channel where gas condensate was found.
As per drilling data, the Enyenra-2A well intersected 69ft of oil pay in the upper channel and 11m of oil pay in the lower channel.
The well also tested a distal portion of a deeper Turonian-age fan where 16ft of gas-condensate sandstones were intersected and an evaluation of the new play is in process.
Kosmos used drillship Deepwater Millennium to drill the well to a total depth of 4,234m in a water depth of 1,674m.
