Dianne Ralston is Chief Legal Officer and Corporate Secretary at SLB, with responsibility for the company’s global legal, compliance and intellectual property functions. Her relationship with the business stretches back to 1998, and her career has since taken her through senior leadership roles at FMC Technologies and TechnipFMC before she returned to SLB as Chief Legal Officer in 2020. Ralston’s deep roots in the energy services sector give her a particularly strong understanding of the legal, operational and strategic complexities surrounding a highly international business.
