Eni, Afren hits ‘quality water’ in Ghana oil probe

25 April 2012, Sweetcrude, ACCRA – Italian energy group, Eni, and Africa-focused Afren said Wednesday they have hit ‘high quality’ water rather than oil in their Nunya-1X exploration well off Ghana.

It was the first well to be drilled in several years in Ghana’s largely unexplored Keta basin, close to the maritime border with Togo.

The well was drilled to a total depth of 4550 metres in a water depth of 1687 metres, using the Marianas semi-submersible drilling rig.

Afren said on Wednesday that the well encountered “thick and high quality water bearing reservoirs.”

But, Osman Shahenshah, the company’s chief executive officer, said the Keta basin “remains a very high potential basin” even in the face of the disappointing development.

Eni is operator of the block with 35% interest while Afren holds a 35% stake, Mitsui (20%) and Ghana National Petroleum Corporation (10%).
