At least 20 vehicles caught fire on Wednesday after a blaze erupted at a Continental Resources shale well site in Oklahoma.
Emergency officials told Reuters that the fire began Wednesday afternoon during completion activities at a rig site just east of Chickasha, Oklahoma.
No injuries or environmental impact have been reported and all employees have been accounted for.
Emergency crews managed to contain the fire around 6 p.m. on Wednesday.
The blaze didn’t start near the well but the well was shut down as a precautionary measure, Enid News said.
A spokesperson with Oklahoma-based Continental Resources told Enid News that the cause of the fire is not yet known.
A diagram produced by University of Kansas diagram and seen by News9 suggests that frack pumps at the site may have caught fire, with the blaze then spreading to several trucks that were connected by metal piping.
A Grady County Emergency Management Department official told Reuters that at least 20 vehicles carrying oilfield equipment caught fire during the incident, but the extent of the damages have not been disclosed yet.
Smoke from the fire forced the Oklahoma Department of Transportation to close some nearby roads for several hours on Wednesday afternoon, the Associated Press said.
