READING, UK – An extended well test by BG Group at the Carioca well offshore Brazil has increased the potential production from the Santos basin discovery.
BG says the test at 3-SPS-74 (Carioca Nordeste) indicated potential production of 28,000 b/d of oil. The well currently is producing 23,400 b/d into the FPSO Dynamic Producer.
Area potential was strengthened with the results of well 4-BRSA-973A-SPS (Abaré) 35 km (22 mi) south of the initial Carioca discovery well and 293 km (182 mi) offshore São Paulo state. Here, wireline samples indicated 28° API oil from carbonates at about 4,830 m (15,846 ft). A drillstem test is scheduled.
ANP has approved a revision of activities and has extended the deadline for a Declaration of Commerciality from November 2011 to December 2013. There is no change to the consortium’s plans and schedule for development and production.
BG Group has a 30% interest in Block BM-S-9 which is comprised of two appraisal areas - Guará and Carioca (Petrobras 45%, operator, and Repsol Sinopec 25%).
