Available in PDF, EPUB and Kindle. Book excerpt: Geothermal energy is an attractive sustainable energy source. Yet project developers need confirmation of the resource base to warrant their time and financial resources. The Geothermal Play Fairway Analysis of the Appalachian Basin evaluated risk metrics that communicate the favorability of potential low-temperature geothermal energy resources in reservoirs more than 1000 m below the surface. This analysis is focused on the direct use of the heat, rather than on electricity production. Four risk factors of concern for direct-use geothermal plays in the Appalachian Basin portions of New York, Pennsylvania, and West Virginia are examined individually, and then in combination: 1) thermal resource quality, 2) natural reservoir quality, 3) induced seismicity, and 4) utilization opportunities. Uncertainty in the risk estimation is 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 may be applied in other sedimentary basins as a foundation for low temperature (50-150 °C), direct use geothermal resource, risk, and uncertainty assessment. Three methods with which to combine the four risk factors were used. Among these, the averaging of the individual risk factors indicates the most favorable counties within the study area are the West Virginia counties of Monongalia, Harrison, Lewis (dubbed the Morgantown-Clarksburg play fairway), Putnam, and Kanawha (Charleston play fairway), the New York counties of Chemung and Steuben plus adjacent Bradford county in Pennsylvania (Corning-Ithaca play fairway), and the Pennsylvania counties of Mercer, Crawford, Erie, and Warren, and adjacent Chautauqua county in New York (together, the Meadville-Jamestown play fairway). These higher priority regions are surrounded by broader medium priority zones. Also worthy of additional exploration is a broad region near Pittsburgh Pennsylvania, for which the available geological data are insufficient to fully analyze the geological risks but yet the population is high. First, to assess the spatial variation in the depth to which one would need to drill to obtain geothermal temperatures that are useful to a future project, the project used bottom-hole temperature data from Appalachian Basin oil and gas exploration. These bottom hole temperature data are abundant but of low quality. Second, the project examined the potential for sufficient water flow rates through rocks to harvest heat from a geothermal well field, considering only natural reservoirs. This analysis provides a very incomplete picture of spatial variability of natural reservoirs because the oil and gas reservoir data lack key properties and are spatially biased toward those locations with profitable amounts of hydrocarbons in the rock pore spaces. Third, in light of the fact that earthquake activity has been induced in several states by subsurface work related to the oil and gas industry, this project examined the potential for similar activity in the Appalachian Basin. Acknowledging that data for such a task are insufficient, we utilized what was available: records of seismic activity, regional estimates of the orientations of stress in the rocks, and locations and orientations of zones of lateral change in rock properties at depths down to several kilometers below Earth's surface. With these data, we created a first approximation of spatially variable risks for induced earthquakes. Because no data existed with which to test the reliability of these methods, the results have a high degree of uncertainty. Fourth, we examined the spatial variability of the above-the-ground factors that contribute to the economical viability of projects to tap low-temperature geothermal resources for direct-use. We worked principally with population density as a regionally known variable that would impact the cost of district heating. The resulting maps omit the ...

Book excerpt: This collection of files are part of a larger dataset uploaded in support of Low Temperature Geothermal Play Fairway Analysis for the Appalachian Basin (GPFA-AB, DOE Project DE-EE0006726). Phase 1 of the GPFA-AB project identified potential Geothermal Play Fairways within the Appalachian basin of Pennsylvania, West Virginia and New York. This was accomplished through analysis of 4 key criteria or 'risks': thermal quality, natural reservoir productivity, risk of seismicity, and heat utilization. Each of these analyses represent a distinct project task, with the fifth task encompassing combination of the 4 risks factors. Supporting data for all five tasks has been uploaded into the Geothermal Data Repository node of the National Geothermal Data System (NGDS). 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. The identified Geothermal Play Fairways are also provided with the larger dataset. Figures (.png) are provided as examples of the shapefiles and rasters. The regional standardized 1 square km grid used in the project is also provided as points (cell centers), polygons, and as a raster. Two ArcGIS toolboxes are available: 1) RegionalGridModels.tbx for creating resource and risk factor maps on the standardized grid, and 2) ThermalRiskFactorModels.tbx for use in making the thermal resource maps and cross sections. These toolboxes contain "item description" documentation for each model within the toolbox, and for the toolbox itself. This submission also contains three R scripts: 1) AddNewSeisFields. R to add seismic risk data to attribute tables of seismic risk, 2) StratifiedKrigingInterpolation. R for the interpolations used in the thermal resource analysis, and 3) LeaveOneOutCrossValidation. R for the cross validations used in the thermal interpolations. Some file descriptions make reference to various 'memos'. These are contained within the final report submitted October 16, 2015. Each zipped file in the submission contains an 'about' document describing the full Thermal Quality Analysis content available, along with key sources, authors, citation, use guidelines, and assumptions, with the specific file(s) contained within the .zip file highlighted.

Book excerpt: Elevated permeability within fault systems provides pathways for circulation of geothermal fluids. Future geothermal development depends on precise and accurate location of such fluid flow pathways in order to both accurately assess geothermal resource potential and increase drilling success rates. The collocation of geologic characteristics that promote permeability in a given geothermal system define the geothermal 'fairway', the location(s) where upflow zones are probable and where exploration efforts including drilling should be focused. We define the geothermal fairway as the collocation of 1) fault zones that are ideally oriented for slip or dilation under ambient stress conditions, 2) areas with a high spatial density of fault intersections, and 3) lithologies capable of supporting dense interconnected fracture networks. Areas in which these characteristics are concomitant with both elevated temperature and fluids are probable upflow zones where economic-scale, sustainable temperatures and flow rates are most likely to occur. Employing a variety of surface and subsurface data sets, we test this 'play-fairway' exploration methodology on two Great Basin geothermal systems, the actively producing Brady's geothermal system and a 'greenfield' geothermal prospect at Astor Pass, NV. These analyses, based on 3D structural and stratigraphic framework models, reveal subsurface characteristics about each system, well beyond the scope of standard exploration methods. At Brady's, the geothermal fairways we define correlate well with successful production wells and pinpoint several drilling targets for maintaining or expanding production in the field. In addition, hot-dry wells within the Brady's geothermal field lie outside our defined geothermal fairways. At Astor Pass, our play-fairway analysis provides for a data-based conceptual model of fluid flow within the geothermal system and indicates several targets for exploration drilling.

This book was released on 2016 with total page 534 pages. Available in PDF, EPUB and Kindle. Book excerpt: This dissertation considers challenges posed by data and models used in geothermal resource assessment and end-use evaluation and consideration of possible development. The application is low-temperature, direct-use geothermal energy in the North-Central Appalachian Basin, specifically portions of New York, Pennsylvania, and West Virginia. Chapters address the statistical analysis of bottom-hole temperature (BHT) data, sensitivity and uncertainty analysis of a model used in estimation of geothermal resources characteristics from BHT data, spatial screening methods for low-temperature, direct-use geothermal energy and propagation of uncertainty through those computations. Statistical analysis of subsurface temperature data focused on methods to correct BHT measurements collected when a well is drilled. Generalized least squares regression accounts for correlated residuals that result from correcting wells in a spatial cluster with a common estimated equilibrium temperature. A nonlinear regression function prevents common modeling problems with polynomial regression. BHT corrections are developed for New York, Pennsylvania, and West Virginia. Uncertainty and global sensitivity analysis techniques were used to analyze a onedimensional, (vertical) heat conduction model that estimated geothermal resource metrics from BHTs and rock column information. Approximate representations of the sedimentary column showed good agreement with predictions from columns with detailed formation thicknesses. Sobol' global sensitivity analysis indicated that the sedimentary formation thermal conductivities and the measured BHT accounted for most of the uncertainty. Favorability for low-temperature, direct-use geothermal energy projects was evaluated by combining four favorability factors: thermal resource, natural reservoir productivity, potential for induced seismicity, and surface cost of a district-heating utilization infrastructure. Several metrics (average, geometric mean, and minimum) were used to aggregate the favorability factors. Simple procedures were developed to evaluate the uncertainty in the three metrics. The analytical approximations of uncertainty of the aggregated favorability metrics generally agreed well with Monte Carlo results. An asymptotic statistical analysis compares quantile estimates based on nonparametric order statistics to those employing the sample mean and variance. The analysis considered normal, Student t, beta (known shape parameters), and three-parameter gamma (known lower bound or known shape) distributions. The range of quantiles over which the order statistics estimators have a smaller variance than the method of moments was indeed surprising.

Available in PDF, EPUB and Kindle. Book excerpt: This report summarizes the activities and key findings of the project team occurring during Phase 1 (August 2014-October 2015) of the Tularosa Basin Geothermal Play Fairway Analysis Project. The Tularosa Basin Play Fairway Analysis (PFA) project tested two distinct geothermal exploration methodologies covering the entire basin within South Central New Mexico and Far West Texas. Throughout the initial phase of the project, the underexplored basin proved to be a challenging, yet ideal test bed to evaluate effectiveness of the team's data collection techniques as well as the effectiveness of our innovative PFA. Phase 1 of the effort employed a low-cost, pragmatic approach using two methods to identify potential geothermal plays within the study area and then compared and contrasted the results of each method to rank and evaluate potential plays. Both methods appear to be very effective and highly transferable to other areas.

Book excerpt: Play fairway analysis (PFA) is a methodology that can improve success rates for geothermal exploration drilling, thus reducing the costs of geothermal projects while facilitating development in new areas. It was originally developed for the oil and gas industry, but has been adapted for discovering geothermal resources over the last decade. The geothermal PFA methodology involves systematically screening a set geographic area for promising qualities typically related to the presence of heat, permeability, and fluid. Successful application of PFA can identify hidden hydrothermal systems. From 2014 to 2021 the U.S. Department of Energy (DOE) Geothermal Technologies Office (GTO) supported the development of PFA for geothermal resources through awards to 11 research teams across the country. The goal of these projects was to advance and adapt PFA for geothermal exploration to produce regional-scale maps that reduce exploration uncertainty. This report is an outcome of the NREL-led PFA Retrospective project, which compiled, synthesized, analyzed the results of GTO's geothermal PFA program. Ultimately, we find that these projects greatly advanced approaches to geothermal exploration and resulted in extensive new data and new discoveries of unrecognized geothermal systems. We used the results to distill best practices in this report and to provide guidance for future applications of geothermal PFA.

This book was released on 2016 with total page 508 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sedimentary basin geothermal resources are attractive sustainable heat sources because of the potential to displace fossil fuels, particularly in cold climate regions. A geothermal resource reconnaissance is presented for the Appalachian Basin surface heat flow, which is calculated at individual wells using temperature-depth data and generalized stratigraphy in a one-dimensional, steady-state, N-layer heat conduction model with two layers of radiogenic heat generation. Basin scale ordinary kriging, a common geostatistical method for geologic field assessment, is juxtaposed to spatially stratified ordinary kriging. The latter employs Poisson wavelet potential field edges to define prospective heat flow sub-provinces. The average structure of the surface heat flow spatial autocorrelation (the semi-variogram) within most sub-provinces is significantly different than the basin scale average structure. Thus, in the Appalachian Basin, for an accurate site-specific assessment of the mean surface heat flow and spatial prediction uncertainty, one should examine spatial autocorrelation at the scale of geologic subregions.
