The coal seams,located about 1,400 meters (4,593feet) beneath the earth’s surface,will be accessed through wells thatare similar to conventional oil andgas wells. The ISCG wells willbe used to convert the coal under-ground in its original seam into syn-gas. The syngas will be piped to theWhitecourt area to fuel new high-efficiency, combined-cycle powergeneration for Alberta’s electricitymarket, providing about 300 MW More than 30 states receive coal from Wyoming, and severalof generation capacity [23].
