Anadarko's successful appraisal at Barqentine supports LNG development offshore Mozambique

By Phaedra Friend Troy

US independent Anadarko Petroleum (NYSE:APC) has drilled a successful appraisal well of the Barquentine natural gas field offshore Mozambique, further supporting the development of a new LNG liquefaction and export facility in the East African country.

Located in Mozambique's Offshore Area 1 in the Rovuma Basin, the Barquentine-2 appraisal well was drilled to a total depth of 13,500 feet (4,100 meters) in waters measuring 5,400 feet (1,650 meters) deep. Located about 2 miles (3 kilometers) east-southeast of the Barquentine-1 discovery well, the appraisal well transected more than 230 net feet (70 meters) of natural gas pay in high-quality Oligocene-age reservoirs.

The Barquentine-2 well indicated that the Oligocene reservoirs are in static pressure communication.

"Our first appraisal of the Barquentine discovery matched our expectations, confirming our seismic modeling and providing confidence in our geologic interpretation of this world-class accumulation," Anadarko Sr. Vice President, Worldwide Exploration Bob Daniels said. 

The Barquentine-2 is the first appraisal of the Windjammer, Barquentine and Lagosta natural gas complex, which is estimated to contain more than 6 trillion cubic feet of recoverable natural gas.

Pre-FEED Awarded for LNG Plant

"We've also taken a major step toward the development of these substantial resources by awarding contracts for pre-FEED (front-end engineering and design) work for a prospective LNG (liquefied natural gas) plant," Daniels said. 

Anadarko has awarded the pre-FEED studies for an LNG plant in Mozambique to KBR and Technip. The pre-FEED will help the project partners determine if the development of an LNG facility will be commercially viable.

"We have significant ongoing exploration and appraisal programs in the Rovuma Basin and look forward to advancing this important project that can provide long-term benefits for the people of Mozambique," he said. 

The drillship will not move to the south to drill the Camarao exploration well, which will also serve as an appraisal of the Windjammer discovery.

Anadarko serves as the operator of the 2.6-million-acre Offshore Area 1 with 36.5 percent interest. Project partners include Mitsui with 20 percent, BPRL with 10 percent, Videocon with 10 percent, Cove Energy with 8.5 percent and Empresa Nacional de Hidrocarbonetos with 15 percent carried interest through the exploration phase.
