Tullow Discovers Hydrocarbons at Tweneboa Offshore Ghana
Tullow Oil announced that the Tweneboa-1 exploration well, drilled in the Deepwater Tano license offshore Ghana, has discovered a significant highly-pressured light hydrocarbon accumulation.
The well encountered 21 meters of net pay and was drilled to a depth of 3,593 meters and is currently being deepened to further assess the discovery and the up-dip limit of a potential deeper fan system.
"Tweneboa is another outstanding discovery offshore Ghana which maintains our 100% success rate in the region," said Angus McCoss, Exploration Director for Tullow Oil. "Substantial upside has been identified, and a material appraisal program will follow. This result has the potential to deliver yet another transformational growth step for Tullow."
The well was optimally located to penetrate multiple targets, including the edge of an undrilled major Turonian fan system. Further drilling will now be required to test core areas within this potentially giant stratigraphic trap where thicker Turonian reservoir sections are mapped. The upside area of approximately 200 square kilometers includes two de-risked prospective parts, Owo and Ntomme.
The Tweneboa-1 well was drilled by the Eirik Raude deepwater rig in a water depth of 1,148 meters some 25 kilometers west of the Jubilee Field. The hydrocarbon accumulation discovered at Tweneboa is in similar-age sands as the nearby, but separate, Jubilee field.
Tullow (49.95%) operates the Deepwater Tano license and is partnered by Kosmos Energy (18%), Anadarko Petroleum (18%), Sabre Oil & Gas (4.05%) and the Ghana National Petroleum Corporation (GNPC) (10% carried interest).
According to Anadarko, once drilling activities are finished at the Tweneboa-1 well, the partnership expects to move the rig to continue activity in the Jubilee field. The partnership also plans to continue an active program offshore Ghana with initial appraisals of three recent discoveries at Odum and Mahogany Deep on the West Cape Three Points Block and Tweneboa on the adjacent Deepwater Tano License. In addition, the partnership expects to continue its exploration program with the Teak prospect on the West Cape Three Points Block and Onyina on the Deepwater Tano License.
