Following a competitive tender, OneSubsea has been appointed to deliver two subsea production manifolds, one electro-hydraulic distribution unit, subsea control systems, toolkits, as well as field services for installation, commissioning, intervention, preservation and maintenance for the Roncador project.

Roncador is said to be one of Brazil’s five largest producing assets. The field has been in production since 1999 but still retains significant reserves potential.

According to SLB, the provision of an effective subsea solution will help improve recovery from the mature oilfield giant.

Much of the technology and equipment will be produced and serviced locally at SLB OneSubsea’s facilities in Brazil.

“This award further strengthens our valued relationship with Petrobras,” said Mads Hjelmeland, Chief Executive Officer of SLB OneSubsea. “Helping our customers extend the life of their assets is core to our strategy, and we are pleased to be supporting the revitalization of Roncador.”

To remind, OneSubsea is a subsea technology and solutions JV backed by SLB (70%), Aker Solutions (20%), and Subsea7 (10%)

Petrobras recently hired OneSubsea to deliver pre-salt subsea production systems and related services for the second development of the Atapu and Sepia oil fields in the Santos Basin. A month later, TechnipFMC was appointed to design, engineer, and manufacture subsea production systems for deployment on the Roncador, Atapu 2 and Sepia 2 projects.

The Brazilian company, as the operator with a 75% equity in the Roncador field, started production from the first two wells of the increased oil recovery (IOR) project in April 2022. Equinor is the partner, holding a 25% equity since 2018. The FPSO P62 works at the field.
