State Survey Experience with the National Geothermal Database system
The document outlines the efforts of the Geological Survey of Alabama (GSA) to enhance data discovery, access, and stewardship of geothermal-relevant geoscience data. It discusses challenges faced, such as disconnects between data creators and scientists, and the need for standardized processes. Lessons learned emphasize the importance of two-way tech transfer and adapting to user needs for successful data management.
State Survey Experience with the National Geothermal Database system
- 1. Object Lessons froma State Survey to Improve Data Discovery, Access, and Stewardship Denise J. Hills, Geological Survey of Alabama Stephen M. Richard, Arizona Geological Survey
- 2. Sponsored by theU.S. Department of Energy under award DE-EE0002850 to the Arizona Geological Survey acting on behalf of the Association of American State Geologists GSA Annual Meeting 29 October 2013
- 3. Goal of NGDS Tomake large quantities of geothermal-relevant geoscience data available to the public by creating a national, sustainable, distributed, and interoperable network of data providers GSA Annual Meeting 29 October 2013
- 4. Role of theGSA In association with the State Oil and Gas board, the Geological Survey of Alabama (GSA) is a repository of all Oil and Gas well information in the state, including: Geophysical well logs (which may have bottom hole temperatures (BHT) recorded) Cores, cuttings, and other physical samples, sometimes with descriptions Fluid production and injection information GSA Annual Meeting 29 October 2013
- 5. Role of theGSA These data may contain information relevant to geothermal resource development This project was the first experience for our agency to generate large quantities of digitally preserved data in a standardized format GSA Annual Meeting 29 October 2013
- 6. Roadblock – “Disconnect”Between Data Creators and Data Scientists Early on, standard data science and archival practices could be confusing for a data creator/provider, including the terminology AZGS provided many useful resources Webinars and workshops were conducted that greatly improved creator/provider’s understanding of expectations and of the data science field GSA Annual Meeting 29 October 2013
- 7. Webinar on Metadata GSAAnnual Meeting 29 October 2013
- 8. Roadblock – DiverseUsers and Data Creators Large project – in theory, one provider per state – each with different research practices, needs, and standards Content models therefore went through numerous iterations, trying to capture all relevant information without unnecessary duplication GSA Annual Meeting 29 October 2013
- 9. Example of IterativeProcess GSA Annual Meeting 29 October 2013
- 10. Roadblock – Dataat GSA Data discoverability often difficult Much of the available information was analog Even digital data was not always “machinereadable” Lack of standardization and documentation of data and metadata Provenance and quality often poor or unknown GSA Annual Meeting 29 October 2013

- 21. GSA/OGB Production Search GSAAnnual Meeting 29 October 2013
- 22. GSA/OGB Production Record GSAAnnual Meeting 29 October 2013
- 23. Alabama Oil andGas Wells Over 18000 permitted wells in the state (including offshore wells) Over 16000 wells have information submitted to NGDS GSA Annual Meeting 29 October 2013
- 24. Alabama Oil andGas Wells More than 13000 wells had logs on file that might contain a BHT measurement Over 30000 geophysical well logs had to be examined for BHT measurements GSA Annual Meeting 29 October 2013
- 25. Alabama Oil andGas Wells In all, GSA submitted more than 11500 BHT measurements from more than 6500 oil and gas wells GSA Annual Meeting 29 October 2013
- 26. Lessons Learned Tech-transferis key to the success of a robust, usable database – and this needs to be two-way Data providers and creators need to be aware of existing standards, how they are used, and how they may be modified to best suit their needs if necessary GSA Annual Meeting 29 October 2013
- 27. Roadblocks Overcome –A Shift in Mindset at GSA In the past, GSA has primarily been data generator, with little concern about interoperability New process: To think about what all different users might need with respect to metadata, for data discovery and access, and for object/data preservation GSA Annual Meeting 29 October 2013
- 28. Moving Forward Anew web search database is in development for the GSA, with a variety of stakeholder needs addressed NGDS Content Models provide a guide for standardization of GSA metadata beyond NGDS While issues of data provenance, quality, and preservation remain for legacy data, standards are being discovered, developed, and applied to any new data (including samples) moving forward GSA Annual Meeting 29 October 2013
