Understand How the Strategic Partnership Between Subsea7, OneSubsea and Equinor Is Shaping the Next Big Productive Leap in the Oil and Gas Sector in Brazil, in a Project With Reserves of More Than 2 Billion Barrels.

The Subsea Integration Alliance, formed by Subsea7 and OneSubsea, has been officially contracted to advance a new and decisive phase of the Bacalhau field project. Operated by Equinor in the Santos Basin, this move signals a crucial development for the Brazilian oil field, consolidating international collaboration in the exploration of vast pre-salt reserves.

Strategic Partnership in the Brazilian Oil Field

Subsea7 and OneSubsea, through their powerful alliance, were chosen to continue the work in Bacalhau. This project is a true milestone, being the first in the Brazilian pre-salt to be developed entirely by an international operator. The collaboration between the companies is essential for the execution of the complex underwater operations required for oil extraction in ultra-deep waters.

The Details of the Million-Dollar Contract in Brazil

The contract covers the supply of essential underwater equipment, such as umbilicals, risers and flowlines (SURF), as well as subsea production systems (SPS). The combined expertise of the Subsea Integration Alliance is vital to ensure safety and efficiency in the installation of all necessary infrastructure for production in this gigantic Brazilian oil field.

A Crucial Asset for Brazil

Located in the strategic Santos Basin, the Bacalhau field is an asset of immense value for Brazil. Equinor operates the field in partnership with other giants in the sector: ExxonMobil, Petrogal Brasil and the state-owned Pré-Sal Petróleo S.A. (PPSA). The development of this field represents a significant advance in the country’s oil and gas production, promising to generate jobs and boost the economy.

The Future of Pre-Salt With Foreign Investment

The collaboration between Equinor and the Subsea7-OneSubsea alliance demonstrates the dynamism and growing confidence in the Brazilian oil and gas market. The presence of international leading operators and suppliers, working together with local partners, opens a unique window of opportunity to transform Brazil’s vast natural resources into wealth and development.

Billion-Dollar Reserves at Stake

The Bacalhau field has estimated recoverable reserves of more than 2 billion barrels of oil equivalent, including the newly incorporated Bacalhau Norte area. This colossal volume confirms the project’s relevance in the global energy landscape and the importance of continuous investments in technology and engineering to enable its safe and profitable exploration.

Instead of burning or burying old tires, an American city is transforming about 2,000 of them into the street itself, paving its first sections with a quieter and more durable rubber asphalt.

China transforms desert-devastated area into the world’s largest artificial forest, planting trees for 60 years, blocking sand that reached Beijing, and creating a “green lung” of 92,000 hectares in a region once considered lost.

Greek island offers free housing for volunteers, but there’s a condition: you need to take care of rescued cats.

Engineers want to carve through Africa with a giant canal to bring water from the world’s second-largest river to a dying lake on the edge of the Sahara Desert that has already lost 90% of its water.

China has deployed snake-shaped robots to slide along power lines, where they have already inspected over 130 kilometers of cables using cameras and sensors to detect damaged wires, worn-out parts, and overheating.

Chile transforms giant mining tires into a new industry in the heart of the Atacama: new plant recycles colossal rubbers discarded by off-road trucks and promises to process 30,000 tons per year in the driest desert on the planet.

Rio Pinheiros catches the attention of those passing by the bike path with less strong odor, more capybaras and birds on the banks, a reduction of up to 55% in organic matter, and a record removal of trash in São Paulo.

Paper money is disappearing from Brazilians’ pockets, with the issuance of new banknotes dropping by 31% from 2020 to 2025, amid the explosion of Pix, which became the most frequent payment method for 46% of the population, while cash plummeted from 42% to 22%.
