Anadarko' s Orca-1 well discovers 190-ft gas pay offshore Mozambique

HOUSTON -- Anadarko Petroleum has discovered a new natural-gas field offshore Mozambique and said it has also completed drilling a well offshore Kenya.

The energy producer said the Orca-1 discovery well encountered about 190 net ft of natural gas pay within the Offshore Area 1 of the Rovuma Basin of Mozambique in a Paleocene fan system.

Anadarko is the operator in the Offshore Area 1 with a 36.5% working interest. Co-owners include Mitsui E&P Mozambique Area 1 Ltd. with 20%; BPRL Ventures Mozambique B.V. with 10%; Videocon Mozambique Rovuma 1 Ltd. with 10% and PTT Exploration & Production PLC with 8.5%. Empresa Nacional de Hidrocarbonetos' s 15% interest is carried through the exploration phase.

“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 ft, in water depths of approximately 3,481 ft.

Anadarko said it also completed drilling its Kubwa well in the L-07 Block offshore Kenya, which encountered noncommercial oil shows in reservoir-quality sands. The company operates the L-07 Block with a 50% working interest. Co-venturers include Total E&P Kenya B.V. with a 40% stake and PTT Exploration & Production PLC with 10%.

“We are very encouraged with our first test of Kenya’s previously unexplored deepwater basin, in which mudlog and well-site evaluation of core data indicates the presence of a working petroleum system with reservoir-quality sands,” Daniels said. “The Kubwa well tested multiple play concepts and provided useful data regarding the prospectivity of our six-million-acre position offshore Kenya. The rig will now mobilize south to drill the Kiboko well.”
