The native hydraulic characteristics of the shallow (35- to 50-m-deep) Felix coal and adjacent strata have been estimated from the results of comprehensive field tests at the Campbell County, Wyoming, site of proposed in situ coal-gasification experiments. The field tests involved withdrawal of water from and water injection into wells completed in the Felix coal. Measurement of the effects of these hydraulic perturbations in terms of water-level fluctuations in wells completed in the coal and adjacent strata provided the data used in the analysis. At the proposed gasification site, the Felix coal consists of two seams. The estimates of hydraulic conductivity of the 3-m-thick Felix No. 1, the shallower of the two seams, range from about 0.3 to 1 m/day. The coefficient of storage of the Felix No. 1 is approximately 2 x 10/sup -2/. Test results indicate that the Felix No. 1 behaves as a very leaky aquifer.
