Italy’s Eni and London-listed Afren have struck out with their Nunya-1X exploration well off Ghana proving water-bearing.

The well was the first probe for several years in the under-explored Keta basin toward the Togo maritime border.

It was drilled with the Marianas semi-submersible drilling rig to a total depth of 4550 metres in a water depth of 1687 metres.

Targeting a large four-way dip closed Upper Cretaceous prospect, the well encountered “thick and high quality water bearing reservoirs”, Afren said on Wednesday.

Afren chief executive Osman Shahenshah insisted that Keta “remains a very high potential basin” despite the exploration reversal.

Eni operates the block on a 35% interest with Afren (35%), Mitsui (20%) and Ghana National Petroleum Corporation with a 10% carry.
