Halliburton Company is an American multinational corporation and the world's second-largest oil service company, responsible for most of the world's fracking operations. The company, incorporated in the United States, has dual headquarters located in Houston and in Dubai. Halliburton's major business segment is the Energy Services Group. KBR, one of Halliburton's former subsidiaries at the time, paid bribes to high-ranking Nigerian officials between 1994 and 2004. Under a deal reached with the U.S. Justice Department, Halliburton agreed to pay $382 million to settle the bribery case. In 2007, Halliburton sold the division and severed its corporate relationship with KBR. The company has been criticized for its involvement in numerous controversies, including its involvement with Dick Cheney – as U.S. Secretary of Defense, then CEO of the company, then vice president of the United States – and the Iraq War, and the Deepwater Horizon, for which it agreed to settle outstanding legal claims against it by paying litigants $1.1 billion.
