Cove Energy announced Tuesday that the Golfinho exploration well, operated by its partner Anadarko Petroleum Corporation, has discovered a new, major natural gas accumulation nearly 20 miles (32 kilometers) northwest of the Prosperidade complex within the Rovuma Basin Area 1 block, Offshore Mozambique.
Highlights from the discovery include:
- Golfinho exploration well encounters separate and independent gas accumulation entirely in Area 1: 20 miles (32 kilometers) northwest of the Prosperidade complex; and only 10 miles (16 kilometers) offshore from planned onshore development facilities providing potential advantages for future development options.
- Significant uplift in Area 1 Rovuma Offshore gas resources – Operator Anadarko estimates that the Golfinho area holds between 13 and 45 trillion cubic feet of gas in place and adds 7 to 20-plus tcf in recoverable gas resources, in addition to the existing Prosperidade recoverable gas resource of 17 to 30-plus tcf.
- Well penetrated 193 net feet (59 net meters) of Natural Gas Pay encountered in two high-quality Oligocene fan systems. Age-equivalent to, but geologically distinct from, the previous discoveries in the Prosperidade complex.
- Drilling to begin at the Atum-1 exploration well once operations completed at Golfinho.
- Gas Tested at circa 100 million standard cubic feet per day from upper layer in Barquentine 1.
The Golfinho exploration well was drilled to a total depth of approximately 14,885 feet (4,537 meters), in water depths of approximately 3,370 feet (1,027 meters). Once operations are complete at Golfinho, the partnership plans to mobilize the Belford Dolphin (DW drillship) drill ship to drill the Atum-1 exploration well.
Additionally, Cove is pleased to announce the results of its third flow test of the Oligocene zone at the Barquentine-1 well at the northern end of the Prosperidade gas complex in Area 1 Rovuma Offshore. Testing of the Barquentine-1 well flowed at a facility-constrained rate of approximately 100 million cubic feet of natural gas per day.
Cove CEO John Craven commented:
“We are thrilled at the success of the Golfinho exploration well, our 11th successful well offshore Mozambique. This new gas accumulation is independent and separate to the Prosperidade gas complex and with successful appraisal could be advantageously developed, given its close proximity to shore and the fact that it completely enclosed in Area 1.”
