TULSA, Okla., April 3, 2018 /PRNewswire/ -- ONEOK, Inc.

Media outlets misinterpreted the company's notification to customers as a reaction to an attack on ONEOK's system. There were no operational interruptions on ONEOK's natural gas pipelines. Affected customers have been advised to use one of the alternative methods of communications available to them for gas scheduling purposes.
