Petróleo Brasileiro S.A. reports success from its extension drilling at exploration well 3-BRSA-891A-RJS in the Iara Evaluation Plan offshore Santos basin concession BM-S-11. The pre-salt well is 8 km (5 mi) from the discovery well and is in 2,279 m (7,477 ft) of water. Formation tests are to be performed to determine productivity.

OGX Petróleo e Gás Participações S.A. reports hydrocarbons in its 1-OGX-31-RJS well in BM–C-41 in shallow waters of Campos basin. An oil column of about 149 m (489 ft) with approximately 48 m (157 ft) of net pay in the Albian section and a column of 59 m (194 ft) with net pay of 23 m (75 ft) in the Aptian section are reported. Drilling of well OGX-31, also known as the Osorno prospect, was concluded at TD of 3,786 m (12,421 ft).

Elsewhere in the Santos basin, Petrobras has halted an extended well test in the Guará area. A pipeline connecting the well to the Dynamic Producer DP platform ruptured. The well was shut- and there was nothing in the pipeline in at the time, so no releases to the water were incurred. Once the incident is investigated and any necessary repairs made, the well test is scheduled to resume.
