Halliburton is one of the world's largest providers of products and services to the global oil and natural gas industry, operating through two main divisions: Completion and Production, which delivers cementing, stimulation, completion tools, and well intervention services; and Drilling and Evaluation, which provides drilling fluids, drill bits, directional drilling, wireline services, and digital analytics solutions. The company serves oil and gas producers across more than 70 countries, with no single customer representing more than 10% of revenue, competing on service delivery, technical proficiency, safety standards, and quality. Halliburton generates revenue by billing energy companies for services and products delivered throughout the reservoir lifecycle, from drilling and evaluation to completion and production optimization.
