Wawa Confirms Additional Hydrocarbons in Deepwater Tano Block

Tullow Oil has confirmed the presence of additional hydrocarbon-bearing formations in the Deepwater Tano Block offshore Ghana with its successful Wawa-1 exploration well, said partner Anadarko Petroleum Corp. on Wednesday.

Wawa-1, which was drilled by Atwood Oceanics' rig Atwood Hunter (DW semisub), encountered approximately 43 net feet (13 meters) of oil pay and 65 net feet (20 meters) of gas condensate pay.

Wawa-1 was drilled in approximately 1,926 feet (587 meters) of water to a total depth of approximately 10,899 feet (3,299 meters).

The discovery extends to presence of hydrocarbon-bearing formations over 6 miles (10 kilometers) north of the Enyenra-3A well, said Anadarko Senior Vice President of International and Deepwater Exploration Bob Daniels in a statement on Wednesday.

"The discovery enhances the value of the TEN [Tweneboa, Enyenra and Ntomme] complex, which is advancing towards submission of a plan of development," said Daniels, adding that the partnership plans further exploration of the Deepwater Tano block with additional wells scheduled at the Okure and Sapele prospects later this year.

Tullow is operator of the Deepwater Tano block with 49.95 percent working interest. Partners include Anadarko and Kosmos Energy with 18 percent working interest each, Sabre Oil & Gas Holdings with 4.05 percent working interest, and the Ghana National Petroleum Corporation with 10 percent carried interest.

Kosmos Senior VP of Exploration Paul Dailly commented, "We look forward to the remainder of our meaningful 2012 exploration campaign in Ghana, which includes the Okure and Sapele prospects.

"At the same time, we are also preparing to spud our first operated well in Cameroon at the Sipo prospect by the end of this year, and we are aggressively pursuing significant exploration opportunities in our positions offshore Morocco, Suriname and Mauritania," Dailly said in a statement on Wednesday.
