Results confirmed the presence of a 200-m (656-ft) deep hydrocarbon column in reservoirs with good permeability and porosity characteristics.
The well, informally known as C1, was drilled around 220 km (137 mi) offshore Rio de Janeiro in a water depth of 2,160 m (7,086 ft). Final depth was 5,780 m (18,963 ft).
The location was 18 km (11 mi) from the first Libra well 3-RJS-731.
Petrobras says the consortium plan further wells to evaluate the 1,550-sq km (598-sq mi) Libra area.
