Anadarko Petroleum’s Golfinho exploration well recently discovered a new, major natural gas accumulation nearly 20 miles (32 km) northwest of its Prosperidade complex within the Offshore Area 1 of the Rovuma Basin off the coast of Mozambique. The Golfinho discovery well encountered more than 193 net ft (59 net meters) of natural gas pay in two high-quality Oligocene fan systems.
“The success of the Golfinho well significantly expands the tremendous resource potential of the Offshore Area 1 in the deepwater Rovuma Basin, with additional opportunities yet to test,” Bob Daniels, Anadarko senior vice president, worldwide exploration, said. “The Golfinho discovery, which is entirely contained within the Offshore Area 1 block, adds an estimated seven to 20-plus Tcf of incremental recoverable resources over a significant areal extent. This new discovery is only 10 miles offshore, providing potential cost advantages for future development options.”
The Golfinho exploration well was drilled to a total depth of approximately 14,885 ft (4,537 meters), in water depths of approximately 3,370 ft (1,027 meters). Once operations are complete at Golfinho, the partnership plans to mobilize the Belford Dolphin drillship to drill the Atum-1 exploration well. The Golfinho area is now estimated to hold 13 to 45 Tcf of gas in place.
At the Barquentine-1 well in the Prosperidade complex, the partnership successfully tested the upper Oligocene zone, which flowed at approximately 100 million cubic ft of natural gas per day. This is the third successful drill-stem test flowing at this facility-constrained rate.
