Anadarko has made a significant discovery in offshore Ghana, at the Owo prospect, in the deepwater Tano Block. The discovery-well encountered approximately 174 net feet of oil pay in two zones of stacked Turonian-age reservoir sands contained within a gross vertical reservoir interval of more than 500ft.

Anadarko has an 18 per cent share in the deepwater Tano Block. Tullow is the operator with a 49.95 per cent share, the other two international co-owners in the discovery have 18 per cent interest and 4.05 per cen interest respectively, with 10 per cent carried-interest belonging to Ghana National Petroleum Corporation.

"Building on the success of Jubilee and Tweneboa, Owo marks the partnership's third substantial discovery offshore Ghana and continues to enhance the gross resource potential of this prolific area and validate the quality of our geologic models. We plan to continue an active drilling program offshore Ghana through the end of this year and into 2011 with multiple appraisal wells planned for both the Tweneboa field and now the adjacent Owo discovery,” said, Anadarko's vice president for worldwide exploration, Bob Daniels.

The Owo-1 well has been drilled to a total depth of approximately 12,765 feet in about 4,685 feet of water. The partnership intends to carry out research in order to finalise a strategic development plan. After the tests are completed, the rig will be mobilised to drill the Onyina prospect also located on the deepwater Tano Block.
