History and Development

ONEOK traces its origins to 1906, when it was established as a local natural gas distribution company serving communities in the United States.

Throughout the 20th century, the company expanded its operations by developing pipeline networks and processing infrastructure to support the growing use of natural gas as an energy source.

Over time, ONEOK evolved from a regional gas utility into a major midstream energy company, focusing on natural gas gathering, processing, and the transportation of natural gas liquids.

A key milestone occurred in 1950, when the company completed its initial public offering (IPO), providing capital to expand infrastructure and broaden operations across multiple U.S. energy regions.

Today, ONEOK operates a large-scale midstream network that supports natural gas and NGL transportation across several producing basins, playing an important role in the U.S. energy infrastructure system.
