Final Report: Low Temperature Geothermal Play Fairway Analysis for the Appalachian Basin

Description

This is a final report summarizing a two-year (2014-16) DOE funded Geothermal Play Fairway Analysis of the Low-Temperature resources of the Appalachian Basin of New York, Pennsylvania and West Virginia. Collaborators included Cornell University, Southern Methodist University, and West Virginia University. As a result of the research, 'play fairways' were identified for further study, based on four risk criteria: 1) the Thermal Resource Quality, 2) the Natural Reservoir Quality, 3) the Risk of Seismic Activity, and the 4) Utilization Viability. In addition to the final report document, this submission includes project 'memos' referred to throughout the report. Many of these same memos are also provided in the submissions with the detailed data products accompanying the relevant risk factor (thermal, reservoir, seismicity, and utilization). This report updates a preliminary version submitted in late 2015 (Submission 559 - See "Reservoir Analysis 2015" below) This file presents the Final Report and Supporting Documents for a Geothermal Play Fairway Analysis of the Appalachian Basin sectors of New York, Pennsylvania and West Virginia. The purpose of this Department of Energy funded effort was to assess the potential for viable low temperature (50-150 degrees C) geothermal energy exploration and development using the methods of Play Fairway Analysis. The resources analyzed occur at depths of 1000 m and greater below the surface, and the application scenarios considered are for direct utilization of the heat. This report illustrates the lateral variability of each of the four risk criteria. This report also illustrates multiple alternative methods to combine those factors in order to communicate the estimated overall favorability of geothermal development. Uncertainty in the risk estimation is also quantified. Based on these metrics, geothermal plays in the Appalachian Basin were identified as potentially viable for a variety of direct-use-heat applications. The methodologies developed in this project and presented in this report may be applied in other sedimentary basins as a foundation for geothermal resource, risk, and uncertainty assessment. Accompanying this report is an Appendix that describes in greater detail the methods used in the analysis, and 17 other technical memos that document criteria, methods and decisions on which the final product was built.

21 The submission includes data pertinent to the methods and results of an analysis of the Surface Levelized Cost of Heat (SLCOH) for US Census Bureau places within the study area. This was calculated using a modification of a program called GEOPHIRES. https://gdr.openei.org/submissions/623
21 This submission comprises the data for Thermal Quality Analysis (project task 1) and includes all of the necessary shapefiles, rasters, datasets, code, and references to code repositories that were used to create the thermal resource and risk factor maps as part of the GPFA-AB project. https://gdr.openei.org/submissions/638
21 This archived dataset contains magnetic and gravity imaging data for the Appalacian Basin, compiled using Poisson Wavelet Multiscale Edge Detection, and stored in a PostGIS database, along with shapefiles and CSVs of relevant data. The archive also includes regional earthquake data going back to 1973 and relevant world stress map data. https://gdr.openei.org/submissions/837
21 This 2015 report is superseded by the November 2016 final report. The largest difference was revision of the Natural Reservoir analysis based on better data and revised methods. There were minor revisions to the analyses of the thermal quality risk factor and the utilization risk factor. Those changes in the components required a reanalysis of each combined risk metric. https://gdr.openei.org/submissions/682
21 This submission revises the analysis and products for Thermal Quality Analysis for the northern half of the Appalachian Basin. It includes a subset of the necessary shapefiles, rasters, datasets, code, and references to code repositories that were used to create the thermal resource and risk factor maps as part of the GPFA-AB project. This subset is those contents that were improved upon during calendar year 2016. Figures (.png) are provided as examples of some shapefiles and rasters. https://gdr.openei.org/submissions/879
21 The files document the analysis of utilization potential in support of Phase 1 Low Temperature Geothermal Play Fairway Analysis for the Appalachian Basin. https://gdr.openei.org/submissions/878
33 Final report and supporting documents for the Low Temperature Geothermal Play Fairway Analysis for the Appalachian Basin. It includes the main body of the report, a Methods appendix, a copy of the Statement of Project Objectives, an brief overview of 17 technical memos, and 17 technical memos. Together, this describes the approach, data, methods, and results. https://gdr.openei.org/files/899/GPFA-AB_Final_Report_with_Supporting_Documents.pdf
21 This submission contains information used to compute the combined risk factors for deep geothermal energy opportunities in the Appalachian Basin. The risk factors are sedimentary rock reservoir quality, thermal resource quality, potential for induced seismicity, and utilization for direct-use heating of neighborhoods. The methods used to combine the risk factors included taking the average, the geometric mean, and the minimum of the four risk factors. Combined risk maps are provided for three different sedimentary rock reservoir metrics. Combined risk maps are also provided for the three geologic risk factors alone (thermal, reservoir, and seismic), and for the three risk factors that exclude reservoir quality (utilization, seismicity, and thermal qualities). https://gdr.openei.org/submissions/880
21 This dataset conforms to the Tier 3 Content Model for Geologic Reservoirs Version 1.0. It contains the known hydrocarbon reservoirs within the study area of the GPFA-AB Phase 1 Task 2, Natural Reservoirs Quality Analysis. The final values for Reservoir Productivity Index (RPI) and uncertainty (in terms of coefficient of variation, CV) are included. https://gdr.openei.org/submissions/561
21 This submission contains information used to compute the risk factors for the GPFA-AB project. The risk factors are natural reservoir quality, thermal resource quality, potential for induced seismicity, and utilization. The methods used to combine the risk factors included taking the product, sum, and minimum of the four risk factors. The files are divided into images, rasters, shapefiles, and supporting information. https://gdr.openei.org/submissions/622
21 This submission contains all data pertinent to the methods and results of a cohesive multi-state analysis of all known potential geothermal reservoirs in sedimentary rocks in our region, ranked by their potential favorability. Favorability is quantified using three metrics: Reservoir Productivity Index for water as the heat-transport working fluid; Reservoir Productivity Index for supercritical carbon dioxide as the heat-transport working fluid; Reservoir Flow Capacity. The first two metrics include engineering inputs to predict production-stage performance of the reservoirs. The third metric includes only geologic properties. The metrics are explained in the Reservoirs Methodology Memo. https://gdr.openei.org/submissions/867
