CASPER, Wyo. — Chesapeake Energy Corp. won't stop its use of hydraulic fracturing in Wyoming, despite calling a halt to using the method in Pennsylvania after a well blowout there last week.
The Oklahoma City-based company halted the use of the practice, also known as fracking, on Thursday, two days after the blowout occurred.
Chesapeake said it would continue the halt until it figured out the cause of the blowout, which dumped thousands of gallons of fluid used in the process into farm fields and streams at the drill site, located near Canton, Pa.
In fracking, water, sand and chemical additives are pumped underground to break up formations that block oil and gas from flowing.
Company spokesman John Dill said the Pennsylvania accident was a "rare, isolated case."
