Anadarko discovers further reserves with Mozambique appraisal well

LNG Industry,

Anadarko Petroleum Corporation has completed the drilling portion of its planned appraisal programme in the discovery area offshore Mozambique.

The final appraisal well in the programme, the Barquentine-4 well, located in Offhsore Area 1 of the Rivuma Basin encountered 525 net feet of natural gas pay and is the company’s ninth successful well in the area.

The Prosperidade compex, which includes the Windjammer, Barquentine, Lagosta and Camarao discoveries, as well as the five subsequent appraisal wells in the block, is estimated to hold recoverable resources of 17 to 30 plus trillion ft3 of natural gas.

"Our appraisal drilling programme in the Prosperidade complex offshore Mozambique delivered outstanding results that provide significant confidence in the vast extent of this accumulation and will be key in achieving third-party reserve certification, as we advance the partnership's world-class LNG (liquefied natural gas) project toward FID (final investment decision)," Anadarko Sr. Vice President, Worldwide Exploration, Bob Daniels said.

"Our next step is to mobilise the drillship to the northern section of our block to begin testing additional high-potential exploration prospects that may expand the resource even further and provide tieback opportunities for future LNG hub facilities."

The Barquentine-4 well is the northernmost well in the Prosperidade complex, approximately 19 miles (30 kilometers) north of the Lagosta discovery well located on the southern end. It is located in water depths of approximately 5400 ft (1650 m). Once operations are complete at Barquentine-4, the drillship will be moved to the northern part of the Offshore Area 1 block to top-set the Atum prospect, and then begin drilling the Golfinho prospect. The partnership's second drillship operating in the area is continuing to carry out an extensive testing programme within the Prosperidade complex.
