  • Exploration discoveries

    Arthur Berman, Contributing Editor

    South America. Petrobras made another light-oil discovery with its Tiro 1-BRSA-658-SPS (1-SPS-57) well in the southern part of the Santos Basin, offshore Brazil, Block BM-S-40. The company estimates recoverable reserves of about 150 million boe of light oil and gas similar to other pre-salt discoveries in the basin. The well is located 6 mi from the previously announced May discovery 1-BRSA-607-SPS (1-SPS-56), and is about 125 mi offshore Sao Paulo state in 900 ft of water. Pay was found in Lower Cretaceous sandstone reservoirs at 6,759 ft. Petrobras has 100% interest. Petrobras completed drilling its Jupiter 1-BRSA-559A-RJS (1-RJS-652A) well in Block BM-S-24 in the Santos Basin, offshore Brazil. The well was announced as a major discovery in January but was suspended because of operational difficulties. Drilling was later resumed to an 18,941-ft TD.
