A plataforma esta localizada cerca de 210 milhas mar de São Paulo, no Pré-Sal da Bacia de Santos, e é composta por rochas sedimentares que contém óleo de baixa viscosidade, o que é característico das reservas do pré-sal.

De acordo com a Petrobras, a camada de óleo foi descoberta após uma campanha de sondagem que começou em setembro de 2022. A empresa estima que a reserva tem potencial para produzir entre 100.000 e 200.000 barris de óleo por dia, dependendo da complexidade da evolução da produção.

"A descoberta da plataforma é mais uma demonstração da capacidade da Petrobras em explorar e desenvolver as oportunidades offshore do Brasil", disse a presidente da empresa, José Ghagliano. "A Bacia de Santos é um dos maiores xerzeiros de óleo do mundo e a gente espera que esta descoberta possa contribuir para aumentar a produção de petróleo no país", acrescentou.

A implantação da plataforma é prevista para começar no meio de 2023, e a produção de óleo é projetada para começar no final de 2025. A Petrobras estima que a plataforma seja capaz de recuperar cerca de 70% do óleo presente na área, o que é considerado um bom desempenho para uma camada de óleo descoberta em uma área tão profunda.

A Bacia de Santos é uma das principais áreas de exploração do pré-sal no Brasil, e a Petrobras já havia descoberto várias outras reservas de óleo em áreas análogas. A empresa também tem planos para mais uma série de exploratórios e produções em diferentes áreas do pré-sal no futuro próximo.

Petrobras discovers new layer of oil in the Santos Basin

The state-owned company announced today the discovery of a new layer of oil in the Santos Basin, through a perfect well, using state-of-the-art technology.

The company, which is responsible for the majority of the country’s oil and gas production, has established a platform called "ituálita" in the Santos Basin, approximately 210 miles off the coast of São Paulo.

The platform is located in sedimentary rocks that contain low-viscosity oil, which is typical of subsalt reservoirs.

According to Petrobras, the oil layer was discovered after a drilling campaign that began in September 2022. The company estimates that the reserve has the potential to produce between 100,000 and 200,000 barrels of oil per day, depending on the complexity of the production evolution.

"This discovery is another demonstration of Petrobras’ ability to explore and develop opportunities offshore Brazil," said the company’s president, José Ghagliano. "The Santos Basin is one of the largest oil-producing basins in the world, and we expect this discovery to contribute to increasing oil production in the country."

The platform is expected to be implemented in mid-2023, and oil production is projected to begin in late 2025. Petrobras estimates that the platform will be able to recover about 70% of the oil present in the area, which is considered a good performance for a layer of oil discovered in an area so deep.

The Santos Basin is one of the main exploration areas for subsalt hydrocarbons in Brazil, and Petrobras has already discovered several other oil reserves in similar areas. The company also has plans for a series of explorations and productions in different subsalt areas in the near future.

Here is a 600-word summary of the content:

Petrobras announced on Friday (14th) the acquisition of new oil accumulations in the lower reservoir of the Búzios field, located in the pre-salt region of the Santos Basin. The discovery was made through tests conducted at a depth of 5,600 meters using electric logging profiles generated by a sonde introduced into a new well.

The tests were performed to identify geological and hydrological characteristics, and the material generated is still being analyzed by Petrobras’ laboratories. The joint venture, the Búzios Shared Reservoir Consortium, formed by Petrobras (88.98%) in partnership with CNOOC (7.34%) and CNPC (3.67%), and managed by Pré-Sal Petróleo S.A. (PPSA), will continue to analyze the results to ensure the continuation of activities in the area.

Brazil’s oil and gas production has been steadily increasing, according to the National Agency of Petroleum, Natural Gas and Biofuels (ANP). In 2024, the average annual production of oil and gas was 4.322 million barrels of oil equivalent per day (boe/d), with 3,358 million barrels per day (bbl/d) of oil produced.

Some 78% of the production came from pre-salt reservoirs, which are located between 1,000 and 6,000 meters below the sea level. The Búzios field, considered the largest in the deep waters, is located off the coast of Rio de Janeiro, 189 kilometers from the coast. It has been in operation on a large scale since March 2015 and exceeded the mark of 1 billion barrels of oil produced in March of this year.

According to the ANP’s Oil and Gas Production Bulletin, in 2024, the Búzios field production increased 2.40% compared to 2023, accounting for 19.53% of marine production. The discovery of new accumulation in the Búzios field is a significant milestone for Petrobras and the Brazilian oil industry, and it is expected to contribute to the country’s energy security and the growth of the industry.
