P-79: new step

Petrobras has completed the tieback of the Búzios 90 well, a step that enables first oil from the P-79 platform in the Búzios field, in the Santos Basin. The unit will have the capacity to produce up to 180,000 barrels of oil per day and compress 7.2 million cubic meters of gas, becoming the eighth platform operating in the field. Start-up now depends only on approval from the Agência Nacional do Petróleo (ANP).

According to the company’s CEO, Magda Chambriard, the platform is ready to begin operations once regulatory clearance is granted. She highlighted the complexity of the work, which involved around 1,300 hours and the installation of 15 km of flexible and rigid lines, as well as umbilicals. The Búzios 90 well is expected to produce about 50,000 barrels per day.

Located about 180 km off the coast of Rio de Janeiro in ultra-deep waters, P-79 is part of the Búzios 8 project, which includes 14 wells — eight producers and six injectors — as well as a gas export pipeline connected to the Rota 3 system.

The tieback campaign was carried out alongside anchoring operations and involved 11 vessels, both owned and contracted. According to the company, the main challenges were managing simultaneous activities on the FPSO and in the subsea environment, as well as logistical constraints.
