A section of a natural gas pipeline that serves customers of Oklahoma Natural Gas Co. exploded Monday morning near Milfay, OK, resulting in gas being released and a fire. It was unclear how many gas utility customers may be affected by the incident.

The pipeline carries gas from Depew, OK, to Edmond, OK. No one was injured and no structures were damaged, Oneok Inc. spokesman Brad Borror told NGI. Company officials were at the scene.

"Oklahoma Natural Gas receives natural gas from this pipeline, and we are working to determine if any of their customers in this area will be affected," Borror said. He did not know the pipeline's capacity.

The explosion could be heard for miles, according to emergency responders who were on the scene within a few minutes after the incident, which occurred at around 11 a.m. CT.

Oklahoma Natural Gas serves nearly 829,000 residential, commercial and industrial customers in the state, including Oklahoma City. The company has affiliates that operate transmission and storage operations in Oklahoma that include more than 2,500 miles of pipeline and five underground storage facilities.

Oneok Gas Storage LLC provides storage for about 45 Bcf of capacity in fields connected to Oneok Gas Transportation LLC. The five storage fields are Haskell, Osage, Edmond, Sayre and Depew, depleted gas reservoirs with maximum injection of about 720 MMcf/d and maximum withdrawal of about 1,610 MMcf/d.
