Less plugged than they thought

Koch, George

Alberta Report / Newsmagazine;1/30/95, Vol. 22 Issue 7, p18
Reports that alarms are being raised by some ranchers on gas-prone lands in east-central Alberta, in the wake of recent studies showing that some 4,000 gas and oil wells in the Wainwright-Lloydminster area of Alberta and Saskatchewan are leaking methane. How much plugging the wells could cost; Discussion of gas migration.
