RIO DE JANEIRO – Petrobras says a second appraisal well in the Libra block in the Santos basin has reached the salt base. Drilling through the reservoir of the LC21 well is expected to follow in the next few days.
On Nov. 6, the Petrobras-led Libra Consortium completed its first appraisal well (NWI) in the northwest portion of the Libra block, 4 km (2.5 mi) southeast of the discovery well 2-ANP-2A-RJS. The location is 185 km (115 mi) from the coast of Rio de Janeiro in a water depth of 1,963 m (3,487 ft).
Results have confirmed a 290-m (951-ft) oil column and a reservoir with good porosity and permeability. Samples collected from the well have confirmed 27° API oil, the same as in the discovery well.
The partners plan a formation test in the oil-bearing zone to verify its characteristics and the reservoir productivity.
