About Us

Oklahoma Natural Gas Company, founded in 1906, is the cornerstone of one of the oldest corporations in Oklahoma. The history of Oklahoma Natural Gas is closely aligned with the history of the state. Oklahoma Natural Gas serves more than 884,000 residential, commercial and industrial customers in Oklahoma. 

Oklahoma Natural Gas is a division of ONE Gas, Inc. (NYSE: OGS), a natural gas distribution company and the successor to the company which became ONEOK, Inc. (NYSE: OKE) in 1980. ONE Gas is one of the largest publicly traded, 100 percent-regulated natural gas utilities in the United States. ONE Gas provides natural gas distribution services to more than 2 million customers in Oklahoma, Kansas and Texas. Headquartered in Tulsa, Okla., its companies include the largest natural gas distributor in Oklahoma and Kansas, and the third largest in Texas, in terms of customers.

ONE Gas is a successor to the company founded in 1906 as Oklahoma Natural Gas Company, and became ONEOK, Inc. (NYSE: OKE) in 1980. ONEOK separated its natural gas distribution business in 2014 to create ONE Gas, Inc.

Oklahoma Natural Gas is committed to being an organization that strives for excellence. Our industry is evolving. There is greater competition and greater customer choice. These changes will yield exciting new opportunities to serve the customers who have trusted us as their reliable source of natural gas. We value that trust. It's been earned by our employees who have made it their business to satisfy customers year after year.

Safety and environmental performance are our top priorities, and we work hard to deliver natural gas service with no adverse effect on the public, our customers, employees or the environment. So when the Office of Pipeline Safety issued a final rule requiring natural gas pipeline operators to develop integrity management programs for natural gas transmission pipelines located in high-consequence areas, Oklahoma Natural Gas created an integrity management program that meets or exceeds the requirements of the integrity management regulations.
