The Anadarko Petroleum Corp. partnership has completed the drilling portion of its appraisal program offshore Mozambique, where the four-discovery gas field in Offshore Area 1 has been named “Prosperidade” (prosperity) by Mozambique middle school children.
The last appraisal well, Barquentine-4, cut 525 net ft of natural gas pay, becoming the partnership’s ninth successful well in the complex in the Rovuma basin.
Prosperidade, estimated to hold 17 to 30 tcf or more of recoverable gas, includes the Windjammer, Barquentine, Lagosta, and Camarao discoveries and five subsequent appraisal wells.
The partnership will mobilize the drillship to the northern part of the block to begin testing more high-potential exploration prospects that may expand the resource even further and provide tieback opportunities for future LNG hub facilities (see maps, OGJ, Apr. 2, 2012, p. 72).
The drillship will 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 in the complex.
