If you’d met John Werring four years ago, he wouldn’t have been able to tell you what an abandoned gas well looked like.
“We had no idea whether they were even accessible,” said the registered professional biologist.
That was before the summer of 2014, when he headed up to Fort St. John, B.C., on a reconnaissance mission. At that time, much was known about leaking gas wells in the United States, but there was very little data on Canada.
All Werring had to work with was a map of abandoned wells provided by B.C.’s Oil and Gas Commission. Armed with a gas monitor and a metal detector, he headed into what the gas industry calls the “Montney formation,” one of the largest shale gas resources in the world. Shale gas is primarily accessed via hydraulic fracturing, also known as fracking.
“Most of these places, there’s nobody in the field,” Werring said. “You won’t see anybody for miles and miles. Just well after well after well.”
