groundwater discharge in the illinois basin as suggested by temperature anomalies
type: Distribution
description: This paper identifies areas where ground water in the Illinois basin is moving vertically should be reflected by temperature anomalies. To test this hypothesis, an isothermal map for a depth of 500 feet was constructed, based on bottom hole temperatures of deep wells. This map was compared with a theoretical isothermal map for a depth of 500 feet that was made by projecting temperature gradients (calculated from the thermal conductivities of the rock) downward from the surface where mean annual air temperatures were known. The residual temperature map that was made on the basis of this comparison (calculated minus observed temperature) shows several warm and cool anomalies that are postulated to be discharge and recharge areas, respectively. Analysis of the curvature of the earth's thermal profile calculated for the basin suggests that approximately 59,000 acre‐feet of ground water per year are discharged upward from the deep rocks in the Illinois basin.

bottom-hole temperature data.xlsx
type: Distribution
description: Bottom-hole temperatures from the Illinois Basin in central Illinois. From this data analysis we found the large variation in temperature at each depth interval prohibited us from using this data alone to determine the thermal gradient. Most temperature records lacked information about when the measurement was taken in reference to the drilling operation or injection and extraction activities. This information is critical so that measurements affected by heating from drilling and brine flow can be disregarded. Includes formation temperature versus depth plot.
