A brief discussion of some gas production experiments, done to better plan for future drilling events. From the paper: "Numerous areas in both the western and eastern United States contain large reserves of gas trapped in very low permeable reservoirs. The Mesa Verde formation in the Piceance, Green River, and Uinta Basins of the Rocky Mountain region for example, contains reserves of trillions of cubic feet of gas. The Brown Shale of Upper Devonian Age in the eastern United States also holds tremendous reserves of natural gas. The Morgantown West Virginia Energy Research Center of the U.S. Energy Research and Development Agency formerly the U.S. Bureau of Mines, as nart of a long term earth fracture systems evaluation program, has concentrated on developing methods for more efficiently producing gas from these marginal reservoirs. As a result of these studies, ERDA and Columbia Gas Transmission Corporation cooperated on a program to drill a series of wells to test the deviated well concept in the economically marginal Upper Devonian gas reservoir."
