Anadarko Petroleum Corporation today announced that with the success of its Barquentine-4 appraisal well, the partnership has completed the drilling portion of its planned appraisal program in the discovery area offshore Mozambique. The Barquentine-4 well, located in Offshore Area 1 of the Rovuma Basin, encountered approximately 525 net feet (160 meters) of natural gas pay, and became the Anadarko partnership’s ninth successful well in the complex.
Additionally, the company announced that sixth- and seventh-grade students at Escola Unidade and Escola Primaria 16 de Junho in Palma Village, Mozambique recently selected “Prosperidade” (Prosperity) as the name for the discovery area in the Offshore Area 1 block. Prosperidade includes the Windjammer, Barquentine, Lagosta and Camarao discoveries, as well as the five subsequent appraisal wells in the block. As previously announced, Prosperidade is estimated to hold recoverable resources of 17 to 30-plus trillion cubic feet of natural gas.
“Our appraisal drilling program 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. “The selection of Prosperidade as the field name is certainly appropriate, as it symbolizes the partnership’s expectations for this area and the opportunities it represents for the people of Mozambique. Our next step is to mobilize 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 5,400 feet (1,650 meters). 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 program within the Prosperidade complex.
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.
