SLB is the world's largest oilfield services company. Operators such as national oil companies and international majors hire it to image reservoirs, drill and complete wells, and run production equipment, but SLB does not own the hydrocarbons. Legally incorporated as SLB N.V. in Curaçao, it has principal offices in Houston, Paris, London and The Hague and trades on the NYSE as SLB. It generated $35.71B of revenue in FY2025 with about 109,000 employees. The company is headquartered in Houston, Texas.
SLB earns fees, product sales and software revenue from oil and gas operators, mostly national oil companies and international majors. Its work is organized around Digital (Delfi cloud software, data and AI), Reservoir Performance (wireline logging, testing, stimulation), Well Construction (directional drilling, drill bits, drilling fluids, cementing) and Production Systems (subsea, surface, artificial lift, midstream equipment and, since July 2025, ChampionX production chemicals). Revenue tracks customer upstream capital spending, with international and offshore markets far larger for SLB than North American shale. A growing share now comes from outside oil and gas, notably data center infrastructure, which SLB is expanding with the planned Kelvion acquisition.
