A global energy services company, Halliburton helps oil and gas producers drill, cement, and fracture wells in more than 70 countries through its Completion and Production and Drilling and Evaluation units, offering everything from drill bits and Landmark software to Zeus electric pumps. Founder Erle P. Halliburton started it in 1919 in Texas after being fired for pushing new cementing ideas, launching with a borrowed wagon, mules, and a pump. He later founded an airline in 1931 that merged into American Airlines.
