Important Note about Large File Downloading

Please note that some datasets available are large and may be slow to retrieve, and/or are so voluminous that they might crash your web browser. This does not necessarily indicate a server failure. The “Full File as CSV” links below indicate if a file is particularly large. The CSV files are compressed, however.

Usually, large datasets are better retrieved using web clients (e.g. GNU Wget, cURL, etc.), or by using a tool to retrieve and display the data (e.g. Geothermal Prospector, or ArcGIS). If you have a tool which you wish to use, you may test its ability to consume the data by downloading the first 50 records within the dataset by using our "Sample 50" links in the table below before attempting to download the entire dataset.

About the Data available for Download

The project participants each submitted thousands of records of data into the SMU Node of the NGDS (SMU operates one of several NGDS ‘nodes’). These data collections were aggregated to populate ten of the different data delivery ‘content models’. Content models are a standardized means of exchanging a particular type of data across the NGDS, such as information about heat flow or borehole temperature values. Information on the NGDS formats, including descriptions of the specific file layouts for all of the 30+ different possible content models, may be found at http://schemas.usgin.org/models/. Because the content models require certain fields to be populated, records without that type of information contain ‘nil:missing’ or ‘-99999’, which account for some of the very large file sizes.

Additionally, the un-aggregated data contribution files are available for download through links below. Unlike the content model formatted data, most of the data submission files are not in a standard format, and are in the units of measure and columnar layouts as the original contributor submitted them. Because some of these datasets contain additional data/information that may be of interest to project developers or researchers that were not used in populating the content models, the decision was made to make them available as discrete datasets.

In all, 20 datasets are available for download:

· The “Aggregated Well Data” file lists all locations included within the other collections, along with some temperature, depth, heat flow and thermal conductivity information;

· The next 10 files are delivered in a ‘content model’ format specified for data exchange via the National Geothermal Data System (NGDS) containing data from across the project team;

· The next 9 are submitted data contribution files. Because most of these are not in a content model format, we have provided documentation of the column order and content for each file in a Column Heading Description PDF file.

NOTE: The full MLKay Technologies Texas Oil and Gas data submission of over 800,000 wells is not available for download as a discrete dataset. However, it was incorporated into the Well Header Observation content model, the Fluid Flux Injection and Disposal content model, the Borehole Temperature Observation content model, the Well Test content model, and the Aggregated Well Data file. Additional data from MLKay Technologies are available for download/export from within the interactive application reachable by selecting ‘login’ from the main welcome screen.

Selecting a Download File Format

Most Files are downloaded using a protocol called Web Feature Services (WFS) and/or Web Map Services (WMS). If you would like to view and manipulate the data in a spreadsheet program such as Microsoft® Excel®, select the option to download a ‘zipped’ version of the dataset as a CSV (Comma Separated Value) file. (These CSV files are refreshed periodically, and every attempt is made to keep them current, but they are not ‘instantly’ updated with each new data submission.) The column headings order and meaning are described in either the ‘about the dataset’ PDF document or through the content model explanation links. The XML format is not designed to be ‘human intelligible’; rather it assumes you have a web client program designed to understand XML format. The XML Schema describes the layout of the XML files to the web client. The Web Map Service (WMS) returns an image of the data points usable as a layer upon a map. The links provided return the capabilities of the service for use in programs such as Esri’s® ArcGIS and others.

Aggregated Well Data

A listing of all sites with point location coordinates from SMU and all of the partner organizations. Bottom Hole Temperature (BHT), depth, heat flow and thermal conductivity values provided; see additional datasets below for more detailed heat flow and temperature data deliveries. Note: some sites are outcroppings, rather than ‘wells’.
