Halliburton Company is the largest oilfield services provider in North America by market share. Although the industry remains fragmented, Halliburton maintains a leading position in hydraulic fracturing and completions, a segment that accounts for nearly half of its revenue. The company also holds strong positions in drilling and completion fluids, where it benefits from deep materials science expertise, as well as in directional drilling. While SLB is widely viewed as the global leader in reservoir evaluation, Halliburton stands out in services spanning the reservoir-to-wellbore activity chain. Its innovations have helped many producers reduce development costs per barrel of oil equivalent, building on operational techniques refined over more than a century.
