An oil-based lubricant known as “mud” spewed from a well head Sunday during drilling for a hydraulic-fracturing well near Beverly, just west of Marietta. About 1,600 gallons leaked from the drill site into a creek that is a tributary of the Muskingum River, said Heather Lauer, a spokeswoman for the Ohio Environmental Protection Agency.
The spill thus far has been confined to that creek, Lauer said. The agency is overseeing the cleanup work, which is being performed by a contractor for Denver-based PDC Energy Inc., the site’s owner.
Michael Edwards, of PDC Energy, said Thursday that workers noticed high pressure at the drill site but could not contain the subsequent leak because of an equipment failure at the well head. PDC Energy has 15 active wells in Ohio and permits for 18 more. There are two other prospective wells on the same pad where Sunday’s leak occurred.
The Morgan County Sheriff’s Office and fire departments were called soon after the leak occurred, Edwards said. Several residents accepted the company’s offer to temporarily move away from the well site, he said.
Contractors were using containment dams to prevent the drilling liquid from drifting further.
