SLB OneSubsea awarded Petrobras subsea boosting contract offshore Brazil

SLB OneSubsea, the joint venture backed by SLB, Aker Solutions, and Subsea7, has secured a contract from Petrobras for two subsea raw seawater injection (RWI) systems to increase recovery from the prolific Búzios field, offshore Brazil.

The two subsea RWI systems, which will support Petrobras’ floating production storage and offloading (FPSO) vessels P-74 and P-75, will each consist of a subsea seawater injection pump, umbilical system and topside variable speed drive.

The subsea RWI systems will help to increase the production of the FPSO vessels, which are currently bottlenecked in their water injection capacities. Once operational, the RWI systems will reduce greenhouse gas (GHG) emissions per barrel of oil as they are a more efficient means of reservoir pressurization to increase recovery when compared with topside injection systems.

“As deepwater basins mature, we see more and more secondary recovery opportunities emerging,” said Mads Hjelmeland, CEO 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.”

As part of this project, SLB OneSubsea will further strengthen its multidisciplinary team in-country, which will cover the full processing value chain from field development to system engineering and life-of-field support. This team will also provide technical support using AI-enabled Subsea Live services, including continuous condition monitoring and access to domain experts.
