Anadarko Provides East Africa Exploration Update

Anadarko Petroleum Corporation (NYSE: APC) today announced the discovery of a new natural gas accumulation fully contained within the Offshore Area 1 of the Rovuma Basin of Mozambique. The Orca-1 discovery well encountered approximately 190 net feet (58 meters) of natural gas pay in a Paleocene fan system. "Discovering another large, distinct and separate natural gas accumulation in the Offshore Area 1 continues our outstanding exploration success offshore Mozambique," said Sr. Vice President, Worldwide Exploration Bob Daniels. "We are designing an initial two-well appraisal program to define the areal extent of the Orca field, which will commence immediately after drilling our Linguado and Espadarte exploration wells. Orca is a single large Paleocene column, and its proximity to shore provides additional options and flexibility for potential future development." The Orca-1 exploration well was drilled to a total depth of approximately 16,391 feet (4,996 meters), in water depths of approximately 3,481 feet (1,061 meters). Anadarko is the operator in the Offshore Area 1 with a 36.5-percent working interest. Co-owners include Mitsui E&P Mozambique Area 1, Limited (20 percent), BPRL Ventures Mozambique B.V. (10 percent), Videocon Mozambique Rovuma 1 Limited (10 percent) and PTT Exploration & Production Plc (8.5 percent). Empresa Nacional de Hidrocarbonetos, ep's 15-percent interest is carried through the exploration phase.

Anadarko strikes gas at Tubarao well in Mozambique

Anadarko Petroleum Corporation (“Anadarko”) today announced the latest in a string of major deepwater natural gas discoveries off the coast of Mozambique. The Tubarão discovery well encountered more than 110 net feet (34 meters) of natural gas pay and no water in a high-quality Eocene-age reservoir that is separate and distinct from the hydrocarbon accumulations in Anadarko s three previous discoveries in the Offshore Area 1 of the Rovuma Basin. The discovery at the Tubarão prospect opens an entirely new play style, which has additional opportunities in Mozambique s Offshore Area 1, Anadarko Sr. Vice President, Worldwide Exploration Bob Daniels said. This is our fourth significant discovery in the offshore Rovuma Basin and further strengthens our confidence in our geologic and geophysical models of the basin. Our seismic imaging indicates Tubarão s areal extent could cover about 15,000 acres that will be better defined with appraisal drilling. In addition, we continue to safely enhance our drilling efficiencies, procedures and methodology in Mozambique, as we drilled this well in half the time of our first exploration wells. The Tubarão discovery well was drilled to a total depth of approximately 13,900 feet (4,237 meters) in water depths of approximately 2,950 feet (898 meters), approximately 18 miles (29 kilometers) off the Mozambique coast. The partnership plans to preserve the wellbore at Tubarão for potential utilization in future testing. Once operations are complete, the partnership plans to mobilize the rig to the previously announced Windjammer discovery, approximately 26 miles (42 kilometers) northeast of Tubarão, to begin a coring program that will be followed by appraisal drilling in the Windjammer, Barquentine, Lagosta complex.

Tullow Oil plc – Significant oil discovery offshore Ghana

Tullow Oil plc (Tullow) announces that the high impact Mahogany-1 exploration well drilled on the West Cape Three Points licence offshore the Republic of Ghana has discovered a significant light oil accumulation based on the results of drilling, wireline logs and samples of reservoir fluid. The well, which is drilling in water depths of 1,320m, has been drilled to a depth of 3,683m and has to date, encountered a gross hydrocarbon column of 270m with 95m of net stacked pay. It is planned to drill to a total depth of approximately 4,200m to test further prospective horizons. Upon reaching the target depth, the well will be suspended pending further evaluation and additional appraisal drilling will be required. The Mahogany-1 well will be tested at a later date as part of the appraisal programme. The Mahogany discovery, a Santonian turbidite stratigraphic trap, opens a new play fairway in the Tano Basin. The structure straddles both the West Cape Three Points and Deepwater Tano licences in which Tullow has interests of 22.9% and 49.95% respectively. Tullow is also the operator of the Deepwater Tano licence. The Mahogany-1 well was drilled using the “Belford Dolphin” - a dynamically positioned fifth-generation deepwater drillship. This is the first exploration well to be drilled under the West Cape Three Points seven-year exploration agreement and follows a 1,076 sq km 3D seismic survey on the block in 2005.
