SLB

SLB (formerly Schlumberger, NYSE: SLB) is the world's largest oilfield-services company and the anchor of AI in oil and gas. Its digital flagship, the Delfi platform, is a cloud environment spanning the upstream lifecycle — exploration, seismic interpretation, reservoir modeling, well construction, and production — and its Lumi data-and-AI layer adds generative and agentic AI on top. In 2026 SLB pushed further with a Digital Marketplace of domain AI agents and models and an "AI Factory for Energy" built with NVIDIA using energy-specific generative models. As a services company selling software and expertise to operators worldwide, SLB is a genuine AI vendor, not merely an adopter. Its value ultimately tracks global upstream oil-and-gas activity and its ability to turn decades of subsurface data and domain models into differentiated software.
