This submission is a follow-up to Distributed Temperature Sensing (DTS) measurements made in Brady observation well 56-1 during the PoroTomo field experiment conducted in March, 2016. The measurements in this data set were made on August 24, 2018 over an approximately 20 hour period. The fiber-optic cable extends to the bottom of the well at 367 m below the wellhead. Measurements were made with a Silixa XT DTS interrogator configured to continuously record in each file a sixty-second average of stokes and anti-stokes readings on a single channel with a bottom hole U-bend. The 2016 data were collected using a Silixia Ultima with 12.5 cm spatial sampling, whereas the XT spatial sampling interval is 25 cm with a temperature resolution of 0.03 °C. Raw, uncalibrated data were converted to a single .MAT file using code provided by Oregon State University's CTEMPs https://ctemps.org/data-processing. The binary Matlab file containing processed Silixa XT data is read using the Matlab statement "load('Brady_25Aug2018_ch1.mat')", which contains the arrays below. Arrays with 2361 rows represent the channels and arrays with 1210 columns represent the one-minute samples.

Well 58-32 (previously labeled MU-ESW1) was drilled near Milford Utah during Phase 2B of the FORGE Project to confirm geothermal reservoir characteristics met requirements for the final FORGE site.

Well Accord-1 was drilled decades ago for geothermal exploration purposes. While the conditions encountered in the well were not suitable for developing a conventional hydrothermal system, the information obtained suggested the region may be suitable for an enhanced geothermal system.

Geophysical well logs were collected in both wells to obtain useful information regarding there nature of the subsurface materials. For the recent testing of 58-32, the Utah FORGE Project contracted with the well services company Schlumberger to collect the well logs. Data exported from the site earth model

This submission contains information used to compute the combined risk factors for deep geothermal energy opportunities in the Appalachian Basin, in the context of a the Play Fairway Analysis project. 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).

The 2015 data submission should be visited to obtain associated shapefiles, which include:
1) definition of the High and Medium priority play fairways (Inner_Fairway, and Outer_Fairway),
2) definition of the US Census Places (usCensusPlaces),
3) places (cities) of interest in the region (Places_of_Interest) identified as geothermal play fairways,
4) the point centers of the raster cells (Raster_Center_Locations), and
5) locations of industries and special-use communities (e.g., colleges and military bases) identified as low temperature heat users (Industries).

The 2015 submission also includes:
1) a methodology memo that explains how the risk factors were combined (GPFA-AB_combining_risk_factors.pdf),
2) the earthquake-based seismic risk map, and
3) supporting information with details of the calculations or processing used in generating these data files. More details on each file are given in the spreadsheet "list_of_contents.xlsx" in the folder "Supporting_Information".

Code used to calculate values is available at https://github.com/calvinwhealton/geothermal_pfa under the folder "combining_metrics". Note that the 2016 code is currently under the branch named "combining_metrics_2016" in the folder called "combining_metrics". This branch may be merged with the master branch in the future.

Many files contained within this submission update and replace the indicated files contained in:

Retrieved from https://gdr.openei.org/submissions/622. doi:10.15121/1261942 *A list of all files contained within this submission is included in the file titled
list_of_contents.csv*

This folder contains information used to compute the risk factors for the GPFA-AB project. The file types in this upload consist of images, rasters, and supporting information. The image files show what the raster files should look like. An image of the raster will have the same name except *.png as the file ending instead of *.tif. The raster files contain the scaled risk factor data (on [0, 5] and [0, 3]) and the combined risk factor data.

The file About_GPFA-AB_Phase1RiskAnalysisTask5DataUpload.pdf contains information inclusive of references utilized and consulted, special use considerations, authorship, etc.

Note that some of the *.tif files were updated with the 2016 data submission, along with their *.png file. The 2015 data file names that these files update are listed in a column in list_of_contents.xlsx. Also note that the updated 2016 files had 3 different reservoir objectives. These are the Reservoir Productivity Index for water as the working fluid (RPIw), the Reservoir Productivity Index for gas (supercritical CO2) as the working fluid (RPIg), and the Reservoir Flow Capacity (RFC) for water as the working fluid. Results are presented with these abbreviated names in the file name.

Note that the thresholds that define the scaled values for the thermal risk factor and the reservoir risk factor changed from the 2015 to the 2016 data submission. The method for calculating the uncertainty of the seismic stress-based risk has also been updated.

Tier 3 data for Appalachian Basin sectors of New York, Pennsylvania and West Virginia used in a Geothermal Play Fairway Analysis of opportunities for low-temperature direct-use applications of heat. It accompanies data and materials submitted as Geothermal Data Repository Submission "Natural Reservoir Analysis 2016 GPFA-AB" (linked below). Reservoir information are derived from oil and gas exploration and production data sets, or derived from those data based on further analysis. Data reported here encompass locations (horizontal and depth), geologic formation names, lithology, reservoir volume, porosity and permeability, and derived approximations of the quality of the reservoir.

These differ from the linked 2015 data submission in that this file presents data for New York that are comparable to those in the other two states. In contrast, the 2015 data available measured differing attributes across the state boundaries. Tier 3 data for natural sedimentary rock reservoirs documented during oil and gas exploration or development for New York, Pennsylvania and West Virginia sectors of the Appalachian Basin. File format in .xlsx and conforms to Geothermal Data Repository Reservoirs Content Model.

These core photos and descriptions were taken from the five boreholes that were drilled as part of the kISMET SubTER project conducted at the Sanford Underground Research Facility (SURF) in Lead, SD. The boreholes are subvertical in orientation, and were drilled on the 4850 level of SURF on the West Drift, about 450 feet from Governor's Corner. The well heads for the five wells are in a line, but the outer two wells (k001 and k005) were deviated to form a five-spot configuration at 50 m depth. Four of the five boreholes have a nominal depth of 50 m and have HQ core - the fifth, located in the center (k003) was drilled to a depth of 100m and has NQ core. The central borehole was used for stress and hydraulic fracturing - the other four boreholes were used for monitoring purposes. Core logging was conducted by Paul Cook (LBNL), Bill Roggenthen (SDSMT), and Drew Siler (LBNL). All core consists of rocks from the Poorman Formation. Some of the core photos are missing. These have been documented in the included spreadsheets labeled with the well name and the word missing. The locations of the boreholes are documented on the included map and spreadsheet. A list of missing photos from the k003 borehole including filenames and estimated sample times.

This archive contains seismic shot field records for 10 profiles located in Camas Prairie, Idaho. The eight numbered .sgy files were acquired using a seismic land streamer system with an accelerated weight drop source and 72 geophones. These 10-Hz geophones were mounted on base plates and dragged behind the seismic source. Shots were acquired every 4 meters along the length of lines 500West, 550 West, 600West, 700West, 800West, 900West, 200South and 200North. The objective was to map stratigraphy and structures related to geothermal fluid flow in the upper few hundred meters. A readme file is included with descriptions of individual files.

The lines names refer to to roads which are numbered relative to the distance from the county seat (the town of Fairfield) along the the main highways. For example, 500 West implies that this north-south street crosses the main road 5 miles to the west of town. The included geologic, topographic, and aerial maps show the labeled seismic lines, while the regional map shows only the line geometry and regional faulting. Pdf images for 500W, 600W, 700W, 800W, and 900W stacked profiles. These final stacks were produced with a standard seismic processing flow that included: datum statics, spiking deconvolution, bandpass filtering, surface wave attenuation through a two-step singular value decomposition approach to estimate and adaptively subtract the ground roll signal, iterative velocity analyses with dip moveout corrections (dmo), amplitude gains, Kirchoff time migration, and a post-stack time to depth correction using dmo-corrected stacking velocity values.

The Portland Basin is a prime location to assess the feasibility of DDU-TES because natural geologic conditions provide thermal and hydraulic separation from overlying aquifers that would otherwise sweep away stored heat. Under the Portland Basin, the lower Columbia River Basalt Group (CRBG) aquifers contain brackish water (1,000-10,000 mg/L TDS), indicating low groundwater flow rates and poor connection with the overlying regional aquifer. Further, CRBG lavas tend to have comparatively low thermal conductivity, indicating that the 400-1,000 ft thick CRBG may be an effective thermal barrier to the overlying aquifer. A temporally and spatially limited previous study of a Portland Basin CRBG aquifer demonstrated that the injection of waste heat resulted in an increase in temperature by more than a factor of two, indicating a high potential for storing heat.

This data submission includes comma delimited .XYZ grid of top Columbia River Basalt (CRBG) elevations in the Portland Basin, a spreadsheet of ArcGIS attribute table for associated data points, a map of data types used to constrain top CRBG, top CRBG structure map created using SMT Kingdom Suite software, and cross sections through top CRBG structure map created using SMT Kingdom Suite software.
