Anadarko Petroleum Corporation recently announced the results of its first flow test offshore Mozambique. The Barquentine-2 well flowed at an equipment constrained rate of 90 to 100 million cubic feet per day (MMcf/d), with minimal pressure drawdown, providing confidence in well designs that are capable of 100 to 200 MMcf/d.
“The test at Barquentine-2 exhibited exceptional flow characteristics, confirmed the deliverability of this reservoir and indicated a low density of development wells may be sufficient to produce the reservoir,” Anadarko Sr. Vice President, Worldwide Exploration, Bob Daniels said in a prepared statement.
Using pre-set gauges in an offset well, Anadarko says it was able to confirm connectivity and reservoir continuity over a distance of more than 3 kilometers. The test also proves the reservoir has very high permeability, meeting the quality specifications for the partnership’s LNG development plans.
The Barquentine-2 well is located in water depths of approximately 5,400 feet (1,650 meters) in the Offshore Area 1 of the Rovuma Basin. The drillstem test was conducted by the Deepwater Millennium drillship, which is expected to be mobilized to the Barquentine-1 location for a second flow and interference test in the complex. The 2012 testing program also includes drillstem tests in the Lagosta and Camarão areas to the south of Barquentine.
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.
