The oil and gas exploration and production company said that the objective of Nunya-1x had been to explore a large four-way dip closed Upper Cretaceous prospect in the block.

Operated by Italian firm Eni, who holds a 35 per cent interest in the Keta Block, the Nunya-1x well was drilled to a total depth of 4,550 metres in a water depth of 1,687 metres using Transocean’s Marianas semi-submersible drilling rig.

Afren chief executive Osman Shahenshah said, “While the Nunya-1x exploration well result is disappointing, it was the first well to test the Upper Cretaceous play on the Keta block and, as such, has provided important data with which to calibrate and further enhance our understanding of this underexplored block in what still remains a very high potential basin.

“We continue to make excellent progress with our wider exploration programme, which has already yielded two significant discoveries year to date, and look forward next to the results of the Ebok North Fault Block exploration well, which has spudded in Nigeria and is drilling ahead towards target.”

Afren holds a 35 per cent carried interest in the Keta Block and, along with Eni, is partnered by Mitsui, who holds a 20 per cent interest and Ghana National Petroleum Corporation, who holds a 10 per cent interest.
