With underground coal gasification (UCG), the actual process takes place underground, generally below 1,200 feet. The underground setting provides both the feedstock source as well as pressures comparable to that in an above-ground gasifier. With most UCG facilities, two wells are drilled on either side of an underground coal seam.
