During 1974, the U.S. Geological Survey began a comprehensive hydrologic study of the oil-shale area in the southeastern Uinta Basin of Utah and Colorado. From 1976 to 1978, six deep test holes were drilled principally to obtain information about aquifers in the Green River Formation of Tertiary age. Information obtained from the drilling project includes description of lithologic samples from core and drill cuttings, temperature and geophysical logs, drilling logs, packer tests, aquifer (pumping and recovery) tests, and analyses of water samples.
