SLB, formerly known as Schlumberger, does not own Subsea7, as they operate as entirely separate independent corporate entities within the global energy services sector. However, the two corporations maintain collaborative commercial relationships and joint ventures on specific deepwater technology and offshore field development projects to combine their respective expertise in subsurface characterization and subsea engineering construction. Each entity maintains its own distinct management structure, public stock exchange listing, and independent governance framework, operating without any parent-subsidiary ownership linkage between them.
