LONDON – Afren has farmed out 17.4% interest in license OPL 310 offshore Nigeria to Lekoil, pending Nigerian ministerial consent. Indigenous company Optimum Petroleum Development is the operator.

TheGSF Transocean Monitor has spudded an exploratory well on the Ogo prospect, a four-way dip-closed structure in Turonian to Albian sandstone reservoirs, with prospective resources of 78 MMboe. The well is drilling at a depth of 3,500 ft (1,067 m) and will likely be followed by a side track to test a new play of stratigraphically trapped sediments that pinch-out onto the basement high, with potential for 124 MMboe of reserves.

Afren will be carried for its share of the costs up to $50 million, and will continue to provide technical assistance to Optimum.

OPL 310 is in the Upper Cretaceous fairway that runs along the West African Transform Margin and is close to the Aje discovery. The block extends from the shallow water continental shelf to deepwater. According to Afren, the block is in an under-explored basin with a proven working hydrocarbon system, close to the Tano basin.

Detailed evaluation has revealed various prospects in the same Turonian, Cenomanian, and Albian sandstone intervals that have broughtdiscoveries offshore Ghana and Côte d’Ivoire to the west. Consultants NSAI assess total potential resources on the license at 476 MMboe.
