CALGARY, Alberta (Reuters) - Talisman Energy Inc shut down its North American hydraulic rock fracturing operations for eight days last month following a fluid release at a shale gas drilling site in Pennsylvania, a spokeswoman said on Friday.
Canada’s fourth-largest independent oil explorer had four “fracking” operations under way across the continent at the time, three in the Marcellus shale in Pennsylvania and one in the Montney shale in British Columbia, Talisman’s Phoebe Buckland said.
Talisman said on its website that a water-based fluid release on December 17 prompted the shutdown of activities at a well in Tioga County, Pennsylvania. There were no injuries and fluid was contained at the well site, it said.
“By shutting down our operations we could find the cause and understand what happened and find a solution,” Buckland said.
Shale gas drillers pump fluids into wells to fracture the rock at various depths to maximize production.
Talisman shares were up 19 Canadian cents at C$22.21 on the Toronto Stock Exchange on Friday morning.
