Tullow sees successful first flow test at Kenya well

Tullow Oil has recorded a successful first flow test of the Ngamia-1 well in Kenya. At the Ngamia-1 well in Block 10BB in Kenya, the first of six drill stem tests has now been completed. The test was carried out in the Lower Lokhone formation. The well flowed 281 barrels of 30 degree API oil per day using a Progressive Cavity Pump. The other tests will be carried out in the Auwerwer reservoirs (formerly Upper Lokhone) which produced very well in the recent tests at the Twiga South-1 well. The mobilization of the drilling rig from Paipai in Block 10A to the Etuko (previously Kamba) location in Block 10BB in Kenya continues on schedule with drilling expected to commence in the first half of May. Tullow operates the Ngamia-1 well and Africa Oil (50%) has a non-operated interest.

Angus McCoss, exploration director of Tullow Oil plc, commented, "The results from the first flow test at Ngamia are also very encouraging and prove the first potentially commercial flow from the Lower Lokhone reservoir section. The remaining tests in the Auwerwer reservoir units will give us a fuller indication of Ngamia's production potential."

Anadarko provides East Africa exploration update

Anadarko Petroleum Corp. (NYSE: APC) has discovered 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 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 senior 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% working interest. Co-owners include Mitsui E&P Mozambique Area 1, Limited (20%), BPRL Ventures Mozambique BV (10%), Videocon Mozambique Rovuma 1 Limited (10%) and PTT Exploration & Production Plc (8.5%). Empresa Nacional de Hidrocarbonetos ep's 15% interest is carried through the exploration phase.

Anadarko also completed drilling its Kubwa well in the L-07 Block offshore Kenya, which encountered non-commercial oil shows in reservoir-quality sands.
