Tullow makes Enyenra find

Flying the flag: The find is additional good news for the Enyenra field, offshore Ghana

UK-listed Tullow Oil has found oil offshore Ghana in its Deepwater Tano licence, the company has announced.

The Enyenra-4A appraisal well hit 32 metres of net oil pay, with pressure data from the oil leg showing the oil found was in touch with that of other wells in the Enyenra light oilfield including the Owo-1 discovery well.

The well was drilled to test the southern extension of the field, just under seven kilometres south west of Enyenra-2A and almost 21 kilometres south of the field’s northern extension, the Enyenra-3A well.

Drilled by drillship Ocean Olympia, the Enyenra-4A well reached a total depth of 4174 metres, with wireline logging indicating a continuous oil column of about 600 metres.

Injectivity tests on the well were underway, Tullow said, with the well to be suspended for later use on completion of operations.

Tullow exploration director Angus McCoss said the company would continue to appraise the field through monitoring pressure gauge systems deployed in several wells within the system.

The drillship will return at a later date to the Deepwater Tano block to perform a drill stem test on the oil zone in the Ntomme-2A well.

Tullow holds an operating 49.95% stake in the Deepwater Tano licence, with Kosmos Energy and Anadarko Petroleum each holding 18% stakes, Sabre with 4.05% and the Ghana National Petroleum Corporation holding a 10% carried interest.
