Petrobras completes 1,300 hours of work and 15 km of subsea lines to connect the Búzios 90 well to the P-79 — the platform is ready to produce 180,000 barrels per day and is just awaiting ANP approval.

Petrobras President confirmed that the P-79 is ready for first oil as soon as the ANP gives the green light — campaign involved 11 vessels and 15 km of subsea lines in ultra-deep waters

Petrobras completed on Thursday (16) the interconnection campaign of the Búzios 90 well to the FPSO P-79 platform, enabling the first oil from the eighth unit of the field.

The announcement was made by President Magda Chambriard, according to the Jornal de Brasília.

The Búzios field is located in the Santos basin, about 180 km off the coast of Rio de Janeiro, in ultra-deep waters of 1,600 to 2,100 meters.

The numbers of the operation

The interconnection campaign required 1,300 hours of work and mobilized 11 vessels simultaneously.

A total of 15 km of flexible, rigid, and umbilical lines were installed on the seabed, according to Petro Notícias.

The P-79 has the capacity to process 180 thousand barrels of oil per day and 7.2 million cubic meters of natural gas per day.

The first well, Búzios 90, is expected to start with 50 thousand barrels per day.

What’s coming next

The P-79 is part of the Búzios 8 project, which plans for 14 wells — 8 producers and 6 injectors.

The produced gas will be transported via rigid pipeline to Route 3, at the Boaventura Energy Complex in Itaboraí (RJ).

The platform left the Hanwha Ocean shipyard in South Korea in November 2025 and was anchored in February 2026.

Ibama granted the environmental authorization on April 6, 2026.

What Chambriard said

“The P-79 is ready for first oil as soon as the ANP approves. For those who think this challenge is small, it involves 1,300 hours of work, 15 km of lines, and significant naval apparatus,” said the president of Petrobras, according to Brazil Energy Insight.

Petrobras’ business plan for 2026-2030 foresees 11 floating units by the end of 2027.

The total production of Búzios is projected to reach 2 million barrels of oil equivalent per day.

Note: final approval from the ANP is still pending for the start of operations, with no confirmed date. This may delay the first oil expected for 2026.
