Global energy technology company SLB has announced a contract award by Petrobras for two subsea raw seawater injection (RWI) systems. The systems, secured by SLB’s OneSubsea™ joint venture, will enhance recovery from the Búzios field, following a competitive tender process.
The subsea RWI systems are designed to address bottlenecks in water injection capacities on Petrobras’ floating production storage and offloading (FPSO) vessels. By improving reservoir pressurization, the systems will boost production and reduce greenhouse gas emissions per barrel of oil compared to conventional topside injection systems.

“As deepwater basins mature, we see more and more secondary recovery opportunities emerging,” said Mads Hjelmeland, Chief Executive Officer of SLB OneSubsea. “Subsea raw seawater injection is a well-proven application with a strong business case that we think should become mainstream. By placing the system directly on the seabed, we free up space and reduce fuel needs for the FPSOs as well as lessen the power needs for the injection systems. It’s a win-win for Petrobras and one that we are very excited about. This contract will consolidate our solid local content presence in the country, contributed by the largest manufacturing plants and state-of-the-art subsea service facilities in Brazil.”

The contract covers the supply of two complete subsea RWI systems for Petrobras’ FPSOs P-74 and P-75. Each system will include a subsea seawater injection pump, umbilical system, and topside variable speed drive.
SLB OneSubsea will expand its in-country multidisciplinary team to deliver the project. The team will manage field development, system engineering, and life-of-field support. They will also provide technical services through AI-enabled Subsea Live™ solutions, offering continuous condition monitoring and access to domain experts.
