Anadarko Petroleum Corporation announced the Tweneboa-1 discovery well offshore Ghana encountered approximately 70 feet of net pay. The well discovered a light hydrocarbon accumulation in similar-age sands as the nearby, but separate, Jubilee field.

"Tweneboa is an outstanding discovery and continues our success in Ghana," said Bob Daniels, Anadarko Sr. Vice President, Worldwide Exploration. "The Tweneboa well was positioned to target multiple objectives, including the edge of this large Turonian fan. We believe there is significant additional upside as we conduct appraisal activity closer to the perceived core of this stratigraphic trap where a thicker reservoir section is mapped. The success of this well also continues to demonstrate the value of our expanding position in this emerging Cretaceous fan play offshore West Africa."

The Tweneboa-1 well, located on the Deepwater Tano License, was drilled, logged and cased to a depth of approximately 11,790 feet, and is being deepened to further assess additional prospective hydrocarbon-bearing zones. It was drilled using the Eirik Raude deepwater rig in a water depth of approximately 3,770 feet approximately 16 miles west of the Jubilee field. 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.
