Anadarko adds 7 to 20+ tcf at Golfinho off Mozambique

By OGJ editors

The Anadarko Petroleum Corp. group has added 7 to 20+ tcf of recoverable gas to its discovered trove offshore Mozambique at an exploratory success nearly 20 miles northwest of its Prosperidade complex.

The Golfinho well, drilled to 14,885 ft in 3,370 ft of water 10 miles offshore, encountered more than 193 net ft of natural gas pay in two high-quality Oligocene fan systems that are age-equivalent to but geologically distinct from the prior discoveries at Prosperidade (see map, OGJ, Apr. 2, 2012).

Anadarko estimated the Golfinho area to have 13 to 45 tcf of gas in place entirely contained in the Offshore Area 1 block. Its proximity to shore implies cost advantages for development options.

The company said Golfinho has a “significant areal extent” and noted that more prospects remain to be tested on the block in the Rovuma basin.

Once operations are complete at Golfinho, the partnership plans to move the Belford Dolphin drillship to drill the Atum-1 exploration well south of Golfinho and west of Prosperidade.

The partnership also drillstem tested the Upper Oligocene at the Barquentine-1 well in the Prosperidade complex. It flowed at a facility-constrained rate of 100 MMcfd of gas.

Anadarko is operator of Offshore Area 1 with a 36.5% working interest. Mitsui E&P Mozambique Area 1 Ltd. has 20%, BPRL Ventures Mozambique BV 10%, Videocon Mozambique Rovuma 1 Ltd. 10%, and Cove Energy Mozambique Rovuma Offshore Ltd. 8.5%. Empresa Nacional de Hidrocarbonetos EP’s 15% interest is carried through the exploration phase.
