Profile: Halliburton delivers products and services to the oil and gas industries. We add value throughout the entire lifecycle of oil and gas reservoirs. Our service starts with exploring and developing, moving through production, operations, maintenance, conversion and refining and ends with infrastructure and abandonment. The drilling and formation evaluation, fluid systems, production optimization, and digital and consulting solutions are our four business segments that offer products and services to upstream oil and gas customers, ranging from the manufacturing of drill bits and other down hole and completion tools to pressure pumping services.
