Halliburton is one of the world's largest oilfield services companies, providing products and services to oil and gas producers across the full well lifecycle — from drilling and evaluation to completion, stimulation, and production optimization. Halliburton operates through two segments: Completion and Production (~57% of revenue), where hydraulic fracturing is the largest product line alongside cementing, artificial lift, well intervention, and specialty chemicals; and Drilling and Evaluation (~43% of revenue), which includes directional drilling, drilling fluids, drill bits, formation evaluation, and subsurface software. Halliburton sells to national oil companies, international oil companies, and independent producers worldwide, and often takes on integrated project management roles for large NOCs. Revenue is driven by drilling and completion activity levels, which follow oil and gas prices and producer capital spending. Internationally (~59% of revenue), Halliburton typically wins multi-year service contracts, while in North America, frac services are contracted on a per-stage or per-job basis. Halliburton's strategy focuses on migrating its fleet toward higher-value, technology-differentiated offerings — including Zeus electric frac, iCruise rotary steerables, and LOGIX drilling automation — rather than competing on price in commoditized markets. Halliburton has identified four international growth engines — unconventionals, directional drilling, well intervention, and artificial lift — that it believes can add $2.5B–$3B in annual revenue over time. Halliburton also holds ~20% of VoltaGrid, a distributed power company targeting data centers and industrial users, where Halliburton serves as exclusive international partner.
