HOUSTON, Feb. 6 -- Having drilled three noncommercial ultradeep wildcats in the eastern Garden Banks area of the Gulf of Mexico, Anadarko Petroleum Corp. said it will continue to pursue its Trade Winds play.

The company said it remains encouraged with the geological concepts the wells were designed to test and that the area is still underexplored for subsalt Miocene-age objectives.

Anadarko drilled to measured total depth of 32,500 ft at the Grand Cayman prospect on Garden Banks Block 561, the program's first prospect. The company plugged the well, two blocks east of Oregano oil field. Anadarko had 35% working interest. Participants were Plains Exploration & Production Co. 30%, Statoil ASA 25%, and Newfield Exploration Co. 10%.

The Andros Deep well on Block 342 north of Llano oil field went to MTD 31,800 ft and was plugged. Anadarko and Hess Corp. each held 50%.

The Norman well on Block 434 east-southeast of Llano field went to MTD 27,700 ft and was plugged. Anadarko operated with 41.25% interest. Participating were Norsk Hydro AS with 22.5%, Plains E&P 15%, Hess 16.25%, and Callon Petroleum Co. 5%.

Anadarko said it is incorporating data from the wells into its seismic modeling and is using the latest seismic imaging technology to identify potential targets below and next to complex salt bodies.
