Oil and gas explorer Tullow Oil has described its drilling of the Enyenra-2A appraisal well in the Deepwater Tano licence offshore Ghana as an “exceptional result”.

Tullow said drilling efforts successfully encountered oil in excellent quality sandstone reservoirs, with solid evidence of communication with the Owo-1 well, confirming that the discovery was a major light oil field.

It said that results of drilling, wireline logs, samples of reservoir fluids and pressure data had shown that Enyenra-2A intersected 21 metres of net oil pay in the upper channel and 11 metres of net oil pay in the lower.

Tullow owns a 49.95 per cent stake in the licence.
