A wellhead tool was the cause of a water vapor leak from a Continental Resources Chickasha, OK, oil rig.
The Grady County Sheriff’s Office and Grady County Emergency Management responded to the scene at 5 a.m. Sunday.
Workers evacuated from the oil rig and deputies advised the residents of a nearby mobile home to evacuate, said Dale Thompson, Grady County emergency management director.
Continental Resources said the leak was caused by an equipment failure.
“We had a failure of a wellhead isolation tool. We are in the process of replacing it. No one on location was in harm’s way at any time,” Kristin Thomas, Continental Public Relations, said.
There were no injuries in the incident.
Emergency responders closed areas of N. 4th St. and Reding Road as a precaution.
Thompson said the situation is not currently dangerous. There’s an outside chance that enough water could come out to release natural gas or oil products at the end. However, workers are currently in the process trying to prevent this. Should some natural gas escape into the air, it is expected to dissipate quickly due to the wind, he said.
Water trucks are currently trying to remove water from the site.
The Grady County Commissioners and Chickasha Fire Department have been advised of the incident in case the situation becomes hazardous, Thompson said.
