The model of these two new platforms is FPSO (Floating, Production, Storage and Offloading) and they will be installed in water depths exceeding 2,000 meters. The P-84 (Atapu) and P-85 (Sépia) platforms will have a daily production capacity of 225,000 barrels of oil/day and a processing capacity of 10 million cubic meters of gas/day, each. The P-84 and P-85 platforms will be constructed in shipyards in Brazil, China and Singapore, with local content reaching 20% in P-84 and 25% in P-85.
Currently, the Atapu and Sépia fields are producing with two platforms, with the P-70 being in the Atapu Field and the FPSO Carioca in the Sépia field. The new P-84 and P-85 platforms will be the second units in their respective fields.
The P-84 and P-85 projects are expected to reduce the intensity of greenhouse gas emissions by 30% per barrel of oil equivalent produced, being among the most efficient FPSOs to operate in Brazil. This reduction is due to the benefits of the all-electric configuration, optimizations in the processing plant to increase energy efficiency, and the use of several technologies, such as: zero routine ventilation (recovery of ventilated gases from cargo tanks and the processing plant), capturing of deep seawater, use of speed variators in pumps and compressors, cogeneration (Waste Heat Recovery Unit), zero routine flaring (torch gas recovery—closed flare), valves with requirements for low fugitive emissions and capture, use and geological storage of CO2 from gas produced.
Petrobras holds a 65.7% stake in the shared reservoir of Atapu, in partnership with Shell (16.7%), TotalEnergies (15%), Petrogal Brasil (1.7%) and and Pré-Sal Petróleo S.A (PPSA) (0,9%), as the Brazilian Government’s representative in the non-contracted area. For the shared reservoir of Sépia, Petrobras holds a 55.3% stake, in partnership with TotalEnergies (16.9%), PETRONAS (12.7%), QatarEnergy (12.7%), Petrogal Brasil (2.4%). Petrobras is the operator of both reservoirs and PPSA acts as manager of the sharing agreement.
