A Joint Venture Formed Between SLB, Aker Solutions, and Subsea Was Created to Help Customers Unlock Cycle Time
Aker Solutions, SLB, and Subsea7, giants in the global oil and gas market, announced the completion of a joint venture operation announced in 2022. This union resulted in the creation of OneSubsea, a company focused on driving innovation and efficiency in subsea production, with the goal of helping customers unlock reserves and reduce cycle time, according to Petronotícias.
OneSubsea is the result of the merger of Aker Solutions’ and SLB’s subsea businesses, two companies with extensive subsea production portfolios and processing technologies. This includes a wide global manufacturing capacity, access to the industry’s largest reserves, and a strong digital field expertise. The company also has unique process integration resources and enhanced research and development capabilities.
The subsea processing capabilities of OneSubsea are considered unmatched in terms of improving reservoir recovery and enabling longer tiebacks. Its exclusive compression technology portfolio has shown potential to reduce infrastructure and cost in developing new energy reserves. Furthermore, subsea projects have proven to be more efficient in terms of carbon emissions compared to surface solutions.
