Upstream oil and gas company Cove Energy, whose subsidiary Cove Energy Mozambique Rovuma Offshore owns an 8.5 per cent working interest in Offshore Area 1, said the Golfinho exploration well was separate to the nearby Prosperidade gas complex.

The gas accumulation is located 32km northwest of the Prosperidade complex has been estimated by operator Anadarko to hold between 13 and 45 trillion cubic feet (tcf) of gas and 7 to 20+ tcf in recoverable gas resources.

Cove chief executive officer John Craven remarked, “We are thrilled at the success of the Golfinho exploration well, our eleventh successful well offshore Mozambique.

“With a successful appraisal it could be advantageously developed, given its close proximity to the shore and the fact that it is completely enclosed in Area 1.”

Anadarko, owner of a 36.5 percent working interest in Offshore Area 1, described the well as having “tremendous resource potential”

“The Golfinho discovery, which is entirely contained within the Offshore Area 1 block, adds an estimated 7 to 20-plus tcf of incremental recoverable resources over a significant areal extent,” said Bob Daniels, worldwide exploration senior vice president at Anadarko.

“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 4,537 metres in water depths of 1,027 metres.

Other partners to Cove and Anadarko in Offshore Area 1 include Mitsui E&P Mozambique Area 1, who owns a 20 per cent interest, BPRL Ventures Mozambique and Videocon Mozambique Rovuma 1, who both hold a 10 per cent stake, and Empresa Nacional de Hidrocarbonetos, whose 15 per cent interest is carried through the exploration phase.

Following the completion of operations at Golfinho, the partnership has said it would mobilise the Belford Dolphin drillship to drill the nearby Atum-1 exploration well.
