  • -catalog service for the web-web map services-web feature services-web coverage service-Application programming interfaceQ: What are Web Services?A: A web service is a resource with functional capabilities that can be invoked via a request (message) sent using the World Wide Web. Web services are the primary means by which digital geoscience information can be shared according to NGDS specifications. Services are well suited to this task for a number of reasons: owing to standardized data requests, they can be accessed from a variety of platforms; they are read-only and preserve data ownership; they come in a number of varieties for different purposes. An important operation of a web service includes the message format used to encode information which is sent to the server in a request, and the encoded information returned by the server. For the Web Map Service (WMS) examples given in Using Applications, the message format of particular interest is the XML encoding used to transmit requested data back to the client computer. Web Feature Services (WFS), which return Open Geospatial Consortium (OGC)—compliant, XML data interchange documents, are currently used by USGIN for data exchange.For a data consumer, using a web service allows you to access a distributed network of data from many sources having disparate data types.

    2. 2. Geothermal – Why is it important? • Large, global resource – 3.4 GWe US installed – 12 GWe worldwide – 12 GWe global under development • Baseload energy, renewable, low emissions • Potential for expansion out of the traditional “hot” regions in the US – +30 GWe hydrothermal “yet-to-find” – +100 GWe possibility for EGS – Significant “low temp” potential • 2 Opportunity for significant growth – but requires more knowledge of and R&D regarding subsurface
    3. 3. GTO Key Goals, Objectives, and Priorities Identify New Geothermal Opportunities • Lowered risk and cost • New prospecting workflow/“Play Fairway” Accelerate a Commercial Pathway to EGS • Frontier Observatory for Research in Geothermal Energy (FORGE) • Reservoir characterization/creation technologies Overcome Deployment Barriers • Regulatory Roadmap: Streamlining • National Geothermal Data System: Reducing upfront exploration cost Additive Value • Co-production and Distributed Power • Strategic Materials Subsurface Engineering Crosscut • Intra- and inter-agency efforts to address common subsurface challenges and better leverage DOE funding 3
    4. 4. NGDS Vision Support the discovery and generation of geothermal sources of energy. The NGDS will provide online access to important geothermal-related data from a network of data providers in order to: • Increase the efficiency of exploration, development and usage of geothermal energy by providing a basis for financial risk analysis of potential sites • Assist state and federal agencies in making land and resource management assessments • Foster the discovery of new geothermal resources by supporting ongoing and future geothermal-related research • Increase public awareness of geothermal energy 4
    5. 5. International Cyber Infrastructure • ‘…Develop publicly available databases, protocols and tools for geothermal resource assessment and ongoing reservoir management to help spread expertise and accelerate development.’ 5
    6. 6. What is the NGDS • Data System, not a Database • Unified by: – Catalog and standardized metadata – Data access protocols and interchange formats 6
    7. 7. Tiered Interoperability 1. Unstructured data • Useful to people but not well suited for machine processing without significant user investment 2. Structured data in a custom format • Immediately suited for machine processing, but user investment required to understand data format 3. Structured data in a standard interchange format • In a community defined format suited for machine processing and integration of multiple data sets with minimal user investment 7 NGDS content model
    8. 8. Interchange Format • Granular approach – Simple, narrowly scoped models – Reuse property elements among models – Standardize units, vocabulary, etc. 8
    9. 9. Current Content Models (Tier 3) • Active Fault/Quaternary Fault • Aqueous Chemistry • Borehole Temperature Observation Feature • Direct Use Feature • Fault Feature • Fluid Flux Injection and Disposal • Geologic Contact Feature • Geologic Unit Feature • Geothermal Area • Geothermal Fluid Production • Geothermal Power Plant • Heat Flow • Heat Pump Facility 9 • • • • • • • • • • • • • • Lithology Interval Log Feature Metadata Physical Sample Powell Cummings Geothermometry Power Plant Production Radiogenic Heat Production Seismic Event Hypocenter Thermal Conductivity Thermal/Hot Spring Feature Volcanic Vents Well Fluid Production Well Header Well Log Observation Well Test Observations

    14. 14. Application of the NGDS • Play Fairway Analysis: Basin-scale analysis of geologic factors which contribute to discovery probability. • Adapting to geothermal will require an analogous, yet unique workflow • Leverages DOE investments in innovative exploration technologies, and data systems (NGDS) • Impact: Enables targeted, and higher probability of success geothermal exploration, coupled with better resource classification 14
