SLB (Schlumberger) & Chevron

Schlumberger (SLB) is one of Chevron's primary oilfield services suppliers, providing drilling, completion, production, and digital reservoir management services across Chevron's global upstream operations. SLB's AI-powered DELFI platform and managed pressure drilling technology are deployed at Chevron's Permian Basin, Kazakhstan (TCO), and deepwater Gulf of Mexico assets.

Why it matters: Chevron's $189B in FY2025 revenue depends on maximizing oil and gas production from complex subsurface reservoirs. SLB's geoscience modeling and directional drilling capabilities enable Chevron to extract more hydrocarbons per well, improving economics. The partnership between the world's second-largest integrated oil company and the world's largest oilfield services company represents billions in annual contract value.
