WELL LOG DATA FOR SERVICE NEEDS TO GO INTO THE WELL LOG CONTENT MODEL (see http://repository.usgin.org/uri_gin/usgin/dlio/542 ). This workbook is designed as a guideline for compiling information from well log headers. Information compiled in this workbook can be used to populate the Well Header data delivery template, Borehole Temperature template and to populate Metadata records for well log documents. Basic information from the header is used to create Well Header features used to index borehole locations with the information associated with the borehole. Typically maximum temperatures are recorded from log headers, and reported as 'bottom hole temperature' using the borehole temperature observation service. Each row in the WellLogInformation sheet in this workbook will correspond to an individual log from a borehole; thus there may be multiple rows per well. For logs that are scanned or digitized and availble as online resources, metadata records will be created. The HeaderURI for a particular borehole (well for simple wells) is the cross-referencing link (foreign key) used to associate the header record, well log metadata, temperature measurements, and other information from a particular borehole.

This spreadsheet is a compilation of borehole temperature observations provided by the Nebraska Oil and Gas Conservation Commissionand compiled by the University of North Dakota, Dept. of Geology & Geological Engineering, 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 17,535 observations are included.

These layer files contain the symbology for portrayal of geothermal features in ArcMap. For the Borehole Temperatures and thermal springs, the color ramp ranges from green (cool) to red (hot) for each feature. For the active faults legend, the FGDC symbology was used (with additions further specifying activity during the early Quaternary). For the volcanic features, well headers and well log information, an arbitrary symbol was chosen.
