Cenovus Energy believes a well case is the culprit in the uncontrolled release at Rush Lake Thermal Facility.
A well case is a large pipe that is placed in the well to support its structure.
The thermal facility north of Paynton suffered a release of water vapour, oil and gas, which was reported on May 9.
Berms have been put in place and at least one farm family was evacuated from the area surrounding the well as the company set up a five kilometre radius around the site.
Cenovus continues to monitor air quality and test for hydrogen sulfide as in the immediate aftermath, residents could smell rotten eggs in the area.
In a statement the company says Rush Lake 1 and 2 are safely shut in.
“We are safely managing and have stabilized a well release, primarily comprised of water vapour, at our Rush Lake 2 thermal facility. We are currently isolating the well pad,” says Cenovus Energy.
The company adds it is working closely with the Saskatchewan Ministry of Energy and Resources and will be conducting a full investigation to identify the cause of the incident.
