The Lagosta-3 appraisal well encountered 577 total net ft (176 m) of gas pay in multiple zones. It was drilled 2 mi (3 km) west of the Lahosta-1 discovery well and 9 mi (15 km) south of Camarao-1, in a water depth of 4,606 ft (1,404 m).
The well will be suspended while the rig is mobilized to drill the Barquentine-4 appraisal well.
Bob Daniels, Anadarko senior VP, Worldwide Exploration said: “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.”
Anadarko has two deepwater drillships currently operating in the area, the second of which is on location at the Barquentine-2 well preparing for drillstem testing.
