Community Geothermal: Subsurface and Seismic Interpretations - Carbondale, CO
This report, developed as part of the Community Geothermal Heating and Cooling Design and Deployment initiative, presents subsurface and seismic interpretations for Carbondale and the surrounding Roaring Fork Valley. The analysis incorporates historical well data, seismic data, geological maps, and cross-sections. Both visualizations and written interpretations of these materials are provided in the report. Authored by retired geophysicist Don Marlin for the Clean Energy Economy for the Region (CLEER) team, the report was prompted by the discovery of a sinkhole in Carbondale. The report is a component of the Carbondale Community Geothermal Coalition's efforts to establish a zero-energy district, which include the design and planned deployment of a thermal energy network for community buildings in Carbondale.

Community Geothermal: Thermal Conductivity Test and Data Analysis Report - Wallingford, CT
공공데이터포털
Report on a formation thermal conductivity test that was performed on the geothermal test bore at Ulbrich Heights at 38 Louis Circle Lane in Wallingford, Connecticut. Data are applicable only within the Wallingford region and should not be extrapolated for other climatic and geographic regions. The analysis assumes no systemic defects in the borehole prior to and during installing and testing. A graphite and Bentonite grouting mixture was assumed to be consistent throughout borehole length. These data were collected as part of the Community Geothermal Heating and Cooling Design and Deployment Grant Program. This associated project's goal is to design and develop a district geothermal heating and cooling system that will serve at least 50% of the heating and cooling load of a 132-unit, affordable housing complex in Wallingford, CT. The project is led by Connecticut Department of Energy and Environmental Protection (DEEP). Borehole drilling and thermal conductivity testing were conducted by Connecticut Wells Inc. and data were analyzed by Geothermal Resource Technologies Inc. (GRTI).

Community Geothermal: Borefield Design, Thermal Conductivity, and Subsurface Modeling Data - Chicago, IL
공공데이터포털
This dataset encompasses the development of a geothermal energy system for the West Woodlawn neighborhood in Chicago, Illinois. This project is part of a broader initiative to design and deploy geothermal heating and cooling systems at a community scale. The dataset includes thermal conductivity test results, calculations for borehole sizing based on the American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) method, as well as simulated thermal loads based on actual energy usage from individual buildings. Also provided here are files used for numerical modeling via COMSOL Multiphysics to simulate borefield design and subsurface thermal behavior. Two manuscripts are attached, which outline the broad objectives of the project and a description of the numerical modeling methodology and results.

DEEPEN Data Catalog for Magmatic Geothermal Systems in the United States
공공데이터포털
This data catalog contains information related to the Training Site Analysis for the Geothermica project "DE-risking Exploration of geothermal Plays in magmatic ENvironments (DEEPEN)." The DEEPEN project aims to reduce exploration risk for geothermal fluids in magmatic systems by developing improved an improved framework for interpretation of exploration data using the Play Fairway Analysis (PFA) methodology. The Training Site Analysis performed for DEEPEN leverages existing datasets to develop a customized PFA approach to exploration for multiple geothermal resource types in magmatic systems (conventional hydrothermal resources, supercritical fluid and superheated steam resources, and superhot EGS resources). This data catalog contains links to publicly available data files related to 8 training sites in the United States. US training sites are: the Cascades/Aleutians PFA project; the Hawaii PFA project, the Oregon Cascades PFA project, the Snake River Plain, Idaho PFA project, the Washington State PFA project, Newberry Volcano, Coso Geothermal Field, and the Geysers Geothermal field. This database contains an overview of these training sites, data sources, and links to publicly available exploration datasets. For the five PFA projects, details on exploration data related to PFA components (heat, fluid, permeability, sometimes seal) are provided, including a summary of data weighting methodologies.

GeoRePORT Case Studies - Coso, WSMR, Dixie Valley, and Chena Hot Springs
공공데이터포털
The Geothermal Resource Portfolio Optimization and Reporting Technique (GeoRePORT) was developed with funding from the U.S. Department of Energy Geothermal Technologies Office to assist in identifying and pursuing long-term investment strategies through the development of a resource reporting protocol. GeoRePORT provides scientists and nonscientists a comprehensive and quantitative means of reporting: (1) features intrinsic to geothermal sites (project grade) and (2) maturity of the development (project readiness). Because geothermal feasibility is not determined by any single factor (e.g., temperature, permeability, permitting), a site?s project grade and readiness are evaluated on 12 attributes pertaining to geological, technical, or socio-economic feasibility. In this paper, we present case studies showing how GeoRePORT can be used to compare geological, technical, and socio-economic attributes between geothermal systems. The consistent and objective assessment protocols used in GeoRePORT allow for comparison of project attributes across unique locations and geological settings. GeoRePORT case studies presented here outline the geological, socio-economic, and technical features of four individual geothermal sites: Coso, Chena, Dixie Valley, and White Sands Missile Range. The case studies illustrate the usefulness of GeoRePORT in evaluating project risk and return, identifying gaps in reported data, evaluating R&D impact, and gathering insights on successes and failures as applicable to future projects.
