Some deepwater Offshore reservoir contain fluids with high Gas-Oil Ratio (GOR) and CO2 content, presenting also a high productivity index (PI) like the ones found in Brazilian Presalt area. All these leads to large production facilities with complex gas processing section, thus constraining the oil processing and storage capacities. In these scenarios, the application of the HISEPTM, a high pressure, dense phase separation technology patented by PETROBRAS enhances production by promptly enabling the separation and reinjection of a major fraction of this CO2-rich associated gas on the seabed as a dense fluid, hence reducing the need for large gas processing plant in the topside, which in turn extends the oil production plateau and accelerates the production.
