Halliburton is North America’s largest oilfield service company as measured by market share. Despite industry fragmentation, it holds a leading position in the hydraulic fracturing and completions market, which makes up nearly half of its revenue. It also holds strong positions in other service offerings like drilling and completions fluids, which leverages its expertise in material science, as well as the directional drilling market.
