Lagosta-3 appraisal well located about 2 miles (3 kilometers) west of the Lagosta-1 discovery Offshore Mozambique has encountered 577 net feet (176 meters) of Natural Gas Pay.
Lagosta 3, the eighth successful well to drill in the world class Windjammer, Lagosta, Barquentine and Camarão (“WLBC”) gas complex, found high quality gas sands not well imaged by seismic data thus confirming the gas accumulation to the western limits of the WLBC gas complex, into what was an unknown area
Pressure readings confirm important reservoir continuity of Lagosta 3 to Lagosta 1 and 2 and to the Windjammer/Camarao wells further north.
Bob Daniels, Anadarko Sr. Vice President, Worldwide Exploration said :”The partnership’s successful appraisal drilling continues to confirm and expand the world-class nature of this massive natural gas accumulation offshore Mozambique”
“The Lagosta-3 well encountered high-quality sands and successfully confirmed an area of the field that was not as well-imaged in our seismic data due to overlying faulting. Additionally, we continue to accelerate our operational learning curve, safely drilling the last two wells faster and more cost effectively than the preceding wells. We expect these drilling-efficiency improvements to translate into significant cost savings over time, as we continue to advance the project.”
The well was drilled to a total depth of approximately 13,715 feet (4,180 meters) in water depths of approximately 4,606 feet (1,404 meters) and will be suspended while the rig is mobilized to drill the Barquentine-4 appraisal well. Anadarko has two deepwater drillships operating in the discovery area offshore Mozambique, the second of which is now on location at the Barquentine-2 well preparing for drillstem testing.
Anadarko is the operator of the 2.6-million-acre Offshore Area 1 with a 36.5-percent working interest. Co-owners in the area are Mitsui E&P Mozambique Area 1, Limited (20 percent), BPRL Ventures Mozambique B.V. (10 percent), Videocon Mozambique Rovuma 1 Limited (10 percent) and Cove Energy Mozambique Rovuma Offshore, Ltd. (8.5 percent). Empresa Nacional de Hidrocarbonetos, E.P.’s 15-percent interest is carried through the exploration phase.
The final investment decision for the project is expected to be made in 2013.
