Underground gas storage in the Leyden lignite mine by Public Service Co. of Colorado was preceded by careful studies of mine records with respect to geologic conditions and investigation of the gas-sealing potential of the rocks surrounding the cavern. The water level in shaft No. 3 in Sept. 1958 was about 100 ft above the coal seam at that point. Wells were drilled into the mine up-dip (east) of the structurally highest point that a mine shaft intersected the coal seams, and gas was injected into the mine, using the mine water as a seal. At least the up-dip part of the mine was gas-tight, and tests were expanded to the rest of the mine, which also proved to be gas-tight. All that remained to complete the preparation of the mine for permanent gas storage was sealing of the old mine shafts.
