Chevron shut down drilling operations at all its gas wells in Pennsylvania after the deadly February 11 explosion and fire in Greene County last week.
Scott Perry of the Pennsylvania Department of Environmental Protection said “work on seven well pads with wells that have been fracked and are awaiting production, or have not yet been fracked, has been suspended since the February 11 blast in Dunkard,” according to the Pittsburg Post Gazette.
Chevron shut down the wells before receiving a request to do so from the Department of Environmental Protection, Perry said.
Inspectors from the DEP “are visiting the sites, and Chevron is inspecting all of its wells statewide,” he said.
The cause of the Dunkard explosion hasn’t been determined. The fire there burned for five days.
“Officials will focus their investigation on a bolt — used to support production tubing that workers were going to run into the well — that appears to have been ejected from the well head,” the Post Gazette said.
On Wednesday, authorities recovered the remains of an oil worker thought to be Ian McKee, who has been listed as missing since the gas well explosion.
McKee, 27, was a field service technician for Cameron International. He lived in Morgantown, W.Va.
“Just before the blast, workers on site said they heard a noise coming from the well, and at least two people — Mr. McKee and another Cameron contractor — ‘approached the well when it lost its integrity,'” Perry said.
