The FPSO Guanabara is, according to Petrobras, the result of years of experience in the pre-salt layer and the most complex oil production unit in the country.

A few days ago, Petrobras started producing oil and natural gas through the FPSO Guanabara, which is the first definitive production system located in the Mero field, in the pre-salt layer of the Santos Basin.
This FPSO-type platform, a floating oil and gas production, storage and transfer unit, has the potential to process up to 180,000 barrels of oil per day and 12 million cubic meters of gas. This amount refers to 6% of production managed by Petrobras, in order to help increase the production forecast by the company. The Mero field corresponds to the third largest oil field in the pre-salt, after Búzios and Tupi.
As announced by Petrobras, the platform reached the pre-salt layer of Santos Basin at the end of January this year. Since then, operations have been carried out to connect it to subsea wells and equipment, in addition to some final tests before starting production. Initially, the FPSO will be associated with six producing and seven injector wells. The platform is expected to reach its highest production rate by the end of the year.
In a note, the director of Production Development at Petrobras, João Henrique Rittershaussen, stated that the FPSO Guanabara is the most complex oil production unit in operation in Brazil, having been conceived in order to combine production capacity, efficiency and reduction of greenhouse gas emissions. According to him, the installation of a project with this technology is the result of more than ten years of learning in the pre-salt layer and of the integrated work between Petrobras, partners and suppliers.

New platform produces enough energy to supply a city of 330,000 inhabitants

The weight of the new platform is 102,443 tons, which, for comparative purposes, is equivalent to 258 Boeing 747s. Its height is 172 meters, equivalent to 4.6 statues of Christ the Redeemer, and its length is 332 meters, which would give three football fields. Furthermore, it has a power generation capacity of 100 megawatts, enough to supply a city of 330,000 inhabitants.
The unit, built and operated by Modec, is located more than 150 kilometers off the coast of Rio de Janeiro state, in water depth that reaches 1,930 meters. In addition to this, three more definitive platforms are expected to come into operation in the Mero field within the horizon of Petrobras' Strategic Plan 2022-2026.
According to the company, the FPSO Guanabara, located in the pre-salt layer of the Santos Basin, has gas reinjection systems, in which the production of gas with a content of 45% of carbon dioxide (CO2), after its own consumption in the FPSO , will be completely reinjected into the deposit, with the aim of maintaining pressure and improving oil recovery, in addition to reducing the release of CO2 into the atmosphere. This process will be carried out alternately with the injection of water (Water Alternating Gas - WAG).

FPSO Carioca becomes Petrobras' largest production platform: unit chartered with Modec, in the pre-salt of the Santos Basin, reaches 175,000 barrels of oil per day

The FPSO Carioca Platform, owned by Brazilian giant Petrobras, reaches 175,000 barrels of oil per day (bpd), approaching its full production capacity.
Petrobras informed that the fourth producing well connected to the FPSO Carioca has come into operation, in the Sépia field, in the pre-salt layer of the Santos Basin. The opening of the last producing well added 41,000 barrels of oil per day (bpd) to the unit – which already produced 134,000 bpd. With that, it became the largest production platform of the Brazilian oil company, at the moment, with 175 thousand bpd.
