LONDON -- Tullow oil has made a discovery with the Tweneboa-1 exploration well in the deepwater Tano license offshore Ghana.

The well encountered 21 m (69 ft) of net pay and was drilled to a depth of 3,593 m (11,788 ft). The well is currently being deepened to further assess the discovery and the up-dip limit of a potential deeper fan system, the company says.

The well, which was drilled by the rigEirik Raude was located to penetrate multiple targets, including the edge of an undrilled major Turonian fan system. Tullow plans to conduct further drilling to test core areas within the stratigraphic trap where thicker Turonian reservoir sections are mapped. The upside area of approximately 200 sq km (77 sq mi) includes two de-risked prospective parts, Owo and Ntomme, the company reports.
