Well 1-BRSA-1205-RNS (1-RNS-158) was drilled in 1,731 m (5,679 ft) of water, 55 km (34 mi) offshore Rio Grande do Norte state. It encountered a 188-m (617-ft) hydrocarbon column with 24º API oil.
A formation test confirmed the reservoir’s satisfactory permeability and porosity, Petrobras adds.
The company and Petrogral, its partner in the BM-POT-17 concession, will continue exploratory activities, with a view to propose a discovery evaluation plan to Brazil’s National Petroleum, Natural Gas and Biofuels Agency (ANP).
BP is currently negotiating to farm into half of Petrobras’ 80% stake.
