Pennsylvania’s Department of Environmental Protection is investigating a serious accident that occurred last week at a Talisman Energy natural gas well drilling site on state forest land in Tioga County, DEP officials announced Tuesday.
The incident led Talisman Energy to temporarily shut down hydraulic fracturing operations at all of the company’s well sites in North America.
The “well control incident,” as the DEP termed it, occurred shortly after noon on Jan. 17 at a Talisman Energy well in Tioga State Forest. The well pad is located in Ward Township, about five miles east of Blossburg.
During the hydraulic fracturing process, fracking fluids and sand were discharged from the well into the air, according to the DEP.
CUDD Well Control, which specializes in handling such emergencies, also responded.No significant amount of natural gas was released and there was no fire or explosion. The fracking fluids were contained within the lined well pad, the DEP said.
The spilled fracking fluids were cleaned up by a contractor and samples were taken to determine if contaminated soil will need to be removed. Samples were also taken from beneath the well pad liner.
Talisman was sent a notice of violation Monday by the DEP and will be required to submit a sampling plan for the site, an analysis of the main cause of the accident, and changes to be implemented in all of its Marcellus Shale operations as a result of the accident.
