The estimates of the amount of natural gas yet to be unearthed through hydraulic fracturing or “fracgas” vary widely, but there is a “determined limit” on coal-to-gas substitution that is “far short of driving coal out of the power market,” according to a new study by members of the Yale Graduates Energy Study Group.

Most of Canada’s natural gas output continues to be unearthed from the Western Canadian Sedimentary Basin of Alberta. However, as U.S. operators have proved, shale gas development, which can be developed at lower prices, is ramping up, with British Columbia’s (BC) Horn River and Montney shales now holding the most promise to revive the country’s dwindling production, Barclays Capital analysts said in a report.
