Petrobras Concludes Drillstem Test in Santos Basin

Petrobras completed a drillstem test (DST) in the Júpiter Discovery Assessment Plan, located in the Santos Basin pre-salt carbonate reservoir. The well Apollonia (3-BRSA-1246-RJS) located approximately 295 km from Rio de Janeiro in a water depth of 2183 m produced fluid samples with a high gas/oil ratio (GOR) and high CO2 content.

The fluid samples will be used to validate the company’s HISEP high-­pressure separation technology, which includes separation and reinjection in the reservoir rocks of the CO2 contained in the produced oil. The HISEP technology is in the early stages of development but has the potential to enable the Jupiter production development pilot project and other projects with high GOR and CO2 fluids, Petrobras said.

The Jupiter area is in the BM-S-24 concession, where Petrobras is the operator with an 80% interest; Petrogal Brazil holds 20% interest.
