This August, Petrobras obtained an environmental license from Ibama to begin seismic survey activities in the Búzios Field, located in the Santos Basin. This will be the second OBN (Ocean Bottom Nodes) acquisition for the field, and the first aimed at 4D monitoring.

The objective is to generate high-quality data using cutting-edge technology to improve the identification of the distribution of oil, gas, and water in the reservoir. The seismic acquisition is expected to start between September and October 2024 and is projected to last for eight months.

The 4D seismic technology will also enable the monitoring of pressure changes and provide information on connectivity, optimizing reservoir management.

"The technology will assist us in identifying new project opportunities for the field, resulting in increased recovery factors and the incorporation of new reserves,” emphasized Sylvia Anjos, Petrobras’ Director of Exploration and Production.

Wagner Victer, Executive Manager of the Búzios Field, added that the 4D seismic project in Búzios will deploy 3,500 nodes sensors across a 780 km² area on the seafloor.

"These devices will be capable of mapping, in the pre-salt layer, oil deposits across a 330 km² area of geological interest to the company, where most of our current production is concentrated. Technology is a key ally for Petrobras in continually surpassing operational efficiency benchmarks,” he stated.

Seismic monitoring in Búzios reflects Petrobras’ commitment to technical excellence and sustainability. The company’s activities in the field are conducted responsibly and safely, minimizing environmental risks and optimizing resources.

Búzios Field

Located 180 km off the coast, the Búzios Field began operations in 2018 and has since recorded outstanding results, including the most productive wells in the country, at depths exceeding 2,000 meters. The thickness of its reservoir is comparable to the height of the Sugarloaf Mountain, and its area covers more than twice the size of Guanabara Bay.

As the world’s largest ultra-deepwater field, Búzios reached the milestone of 1 billion barrels of oil produced this year since it began operations in 2018.
