US oil and gas explorer Anadarko Petroleum has made its seventh natural gas discovery in the Rovuma Basin, offshore Mozambique. The Lagosta-2 appraisal well is located 7km north of the Lagosta discovery and 8.5km south of the Camarao well.
The company encountered 777 net feet of natural gas pay in multiple zones. The appraisal well was drilled to a total depth of 14,223ft in water depths of 4,813ft in Offshore Area 1 of the Rovuma Basin.
Anadarko will preserve the Lagosta-2 well for future use during its drillstem testing programme in the Windjammer, Barquentine and Lagosta complex. The Belford Dolphin deepwater drillship will be mobilised to drill the Lagosta-3 appraisal well once operations are complete.
Anadarko senior vice-president Bob Daniels said that the well has the largest pay count in the complex.
"These excellent results continue to support our recoverable resource estimates of 15 to 30-plus trillion cubic feet of natural gas in the discovery area on our block, as well as provide additional information to help determine the optimal subsea development plans for the complex" said Daniels.
In addition, a second deepwater drillship, Deepwater Millennium, reached Mozambique to begin an accelerated testing programme, which will involve installing observation gauges and conducting several drillstem tests. A final investment decision for this project will start in 2013.
Anadarko is the operator of the 2.6 million acre Offshore Area 1 with a 36.5% working interest.
