SLB’s OneSubsea has won a contract for two subsea raw seawater injection (RWI) systems to increase recovery from Petrobras’ prolific Búzios field.
The systems will help to increase the production of FPSO vessels, which are currently bottlenecked in their water injection capacities. Once operational, the RWI systems will reduce GHG emissions per barrel of oil as they are a more efficient means of reservoir pressurization to increase recovery when compared with the conventional alternative of topside injection systems.
Under the contract, won following a competitive tender, OneSubsea will provide two complete subsea RWI systems to support Petrobras’ FPSOs P-74 and P-75, and they will each consist of a subsea seawater injection pump, umbilical system, and topside variable speed drive.
As part of this project, 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.
“As deepwater basins mature, we see more and more secondary recovery opportunities emerging. 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,” said Mads Hjelmeland, CEO of SLB OneSubsea.
Earlier this week, SLB won a contract from Petrobras for integrated services across all the operator’s offshore fields in Brazil. Under the contract, worth $800m, SLB will oversee the construction of more than 100 deepwater wells, utilising advanced drilling, cementing and drilling fluids technologies on up to nine ultra-deepwater rigs.
The services will primarily be provided in the Campos, Santos, and Espírito Santo Basins, along with other Petrobras-operated fields, including exploratory wells. |
