This Well Header data set contains basic information describing well boreholes in Illinois associated with thermal properties. Each well header has a separate record (rows) for each well bore. The data set contains 6321 records.

This document contains the metadata records for Illinois well logs. It is a spreadsheet with 6321 records. There are 8 worksheets.

This spreadsheet is a compilation of borehole temperature observations compiled by the Illinois State Geological Survey, published as a Web feature service for the National Geothermal Data System. The document contains 6 worksheets, including information about the template, notes related to revisions of the template, Resource provider information, the data, a field list (data mapping view) and a worksheet with vocabularies for use in populating the spreadsheet (data valid terms). Data from 6321 wells are included.
