Petrobras completed the training test in the Jupiter Discovery Assessment Plan area, located in the Santos Basin pre-salt. The results obtained confirm the excellent productivity of the well, which contains condensed oil of very high added value, with high flow rates, thus reinforcing the potential of the area.

The fluid has a high gas-oil ratio and a high CO2 content, requiring the application of innovative technologies for its commercial production. For this reason, the fluid samples collected in the test will be used for validation of the HISEP® High Pressure Separation technology (developed at high pressure), developed and patented by Petrobras, which consists of the separation and reinjection in the reservoir rocks, using installed equipment. at the bottom of the sea, from the CO2 in the oil produced. HISEP® is in the qualification stage and a pilot, in another area operated by the company, should be installed in 2024 to carry out longer term tests, enabling a new concept of production development.

This technological innovation has the potential to enable the Jupiter production development pilot project, as well as other projects with high gas-oil ratio fluids and CO2 content, opening a new exploratory and production development frontier for opportunities in the portfolio of Petrobras' deep and ultra-deep waters.

The Jupiter area belongs to the BM-S-24 concession, in which Petrobras is the operator, with an 80% interest, and was acquired in 2001 in partnership with Petrogal Brasil, which owns the remaining 20%, in the 3rd Round of Bids from the National Petroleum, Natural Gas and Biofuels Agency (ANP). The formation test evaluated the pre-salt carbonate reservoirs in the well internally called Apollonia (3-BRSA-1246-RJS), located approximately 295 km from the city of Rio de Janeiro, in a water depth of 2,183 m.
