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.

This information is critical so that measurements affected by heating from drilling and brine flow can be disregarded.

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\u2010feet of ground water per year are discharged upward from the deep rocks in the Illinois basin.", "format": "HTML", "mediaType": "text/html", "title": "Groundwater Discharge in the Illinois Basin as Suggested by Temperature Anomalies"}], "identifier": "https://data.openei.org/submissions/8346", "issued": "2018-06-13T06:00:00Z", "keyword": ["geothermal", "energy", "DDU", "Deep Direct-Use", "University of Illinois", "Illinois Basin", "temperature profile", "DTS", "distributed temperature sensing", "temperature gradient"], "landingPage": "https://gdr.openei.org/submissions/1059", "license": "https://creativecommons.org/licenses/by/4.0/", "modified": "2025-02-17T17:45:03Z", "programCode": ["019:006"], "projectLead": "Arlene Anderson", "projectNumber": "EE0008106", "projectTitle": "Geothermal Heat Recovery Complex: Large-scale, Deep Direct-Use System in a Low-Temperature Sedimentary Basin", "publisher": {"@type": "org:Organization", "name": "University of Illinois"}, "spatial": "{\"type\":\"Polygon\",\"coordinates\":[[[-167.7267,13.518],[-53.8316,13.518],[-53.8316,75.0714],[-167.7267,75.0714],[-167.7267,13.518]]]}", "title": "University of Illinois Campus Deep Direct-Use Feasibility Study - Subsurface Temperature Profile"}
