Oneok Inc /new/
A Tulsa, Oklahoma energy infrastructure company that moves natural gas and natural gas liquids through roughly 60,000 miles of pipelines, gathering, processing, and fractionating them for utilities, producers, and refiners across the US. It traces back to the Oklahoma Natural Gas Company, founded in 1906, and adopted the name ONEOK in 1980 as a phonetic play on its Oklahoma roots — it is pronounced "one-oak." The company's work quietly underpins everyday heating, cooking, and the petrochemicals used in countless household products.
