The objectives of this project were to (1) perform a literature review of sedimentary geothermal resources, (2) identify data sources and develop data-collection methodologies that characterize selected resources, (3) screen sedimentary basins and formations for sedimentary geothe...
A downhole tubing bending study was made and is reported herein. This study developed a model to predict the shape of the pipe at downhole conditions and determines if the various pipe string sizes can reach a specified landing depth. The wellbore trajectory is described by this s...
Files include daily mud reports for GLADE East and GLADE West wells in the DJ Basin, Colorado. Reports include daily mud data summaries for each well while drilling. The Mud Reports summarize mud composition and volumes each day throughout the project.
The Geothermal Limitless A...
Project Hotspot applies innovative approaches to geothermal exploration in the Snake River Volcanic Province. This report summarizes results from our Phase 1 data compilation.
This package includes data and footage from two rounds of downhole camera surveys performed at the Sanford Underground Research Facility (SURF) on the 4850 level. The exercise was performed once on 25 May 2018 and once on 21 December 2018. On May 25th, the first round was done dur...
Validation of Innovative Exploration Technologies for Newberry Volcano: Temperature Readings from 7 wells drilled to date by SMU 2012
Polycrystalline diamond compact (PDC) bits are routinely used in the oil and gas industry for drilling medium to hard rock but have not been adopted for geothermal drilling, largely due to past reliability issues and higher purchase costs. The Sandia Geothermal Research Departmen...
This folder contains the GEOPHIRES codes and input files for running the base case scenarios for the six deep direct-use (DDU) projects. The six DDU projects took place during 2017-2020 and were funded by the U.S. Department of Energy Geothermal Technologies Office. They investiga...
FMI image log and mud log of well 52B-7
This is a 74 page detailed summary of the drilling activities of Utah FORGE 16A(78)-32, a highly deviated well completed on February 2nd, 2021, as part of the Utah FORGE project. This well was deviated at 65 degrees from vertical after reaching 6000 feet in depth had a total measu...
A presentation with notes showing an overview of the last 6 months of the project on high-temperature self-healing inorganic cement composites. General approach, test methods and results for the self-healing cement composites are presented. Data include strength recoveries for 9 c...
This is an electronic database detailing different types of, various phases of, best practices for, and cost and time associated with geothermal exploration techniques. The groups of exploration techniques included in the database are Data and Modeling Techniques, Downhole Techniq...
The FORGE team is making these fracture models available to researchers wanting a set of natural fractures in the FORGE reservoir for use in their own modeling work. They have been used to predict stimulation distances during hydraulic stimulation at the open toe section of well 1...
This is a YouTube video containing the specifics of well planning for Utah FORGE 16B(78)-32. This well will be drilled as a doublet approximately 300 feet parallel to and above 16A(78)-32 and will be drilled between approximately April 15th and July 17th 2023.
The problem of loss circulation in geothermal wells is inherently challenging due to high temperatures, brittle rocks, and presence of abundant fractures. Because of the inherent challenges in geothermal environments, there are limitations in selecting proper lost circulation mate...

Plugging of fracture porosity from mineral precipitation due to injecting cold water into a a geothermal reservoir can impact the overall permeability of the fracture network in the reservoir. This can have serious ramifications on the efficiency of the geothermal resource. Geoche...
Abstract: Davenport Newberry (Davenport) has completed 8 years of exploration for geothermal energy on Newberry Volcano in central Oregon. Two deep exploration test wells were drilled by Davenport on the west flank of the volcano, one intersected a hydrothermal system; the other ...
Files include daily operational and drilling reports for GLADE East and GLADE West wells in the DJ Basin of Colorado. Reports include drilling summaries for work done and progress made daily for each well. There is a companion Final Drilling Report that summarizes some of the data...
The submitted dataset was generated by a series of laboratory fracture clogging (permeability reduction) experiments using commercially available materials used for lost circulation management during geothermal well drilling. The experiments were conducted using a permeability plu...
The following information is provided about the design of deeps wells constructed in the Illinois Basin to store, sequester, or dispose of CO2, natural gas, and industrial wastes.
This collection includes datasets used for the analyses and modeling of low-temperature geothermal resources at the U.S. Army's Detroit Arsenal located in Warren, Michigan. This project file includes tabular and geospatial data accessed from publicly available repositories held by...
Polymer-cement experiments were conducted in order to assess the chemical and thermal properties of various polymer-cement composites. This file set includes the following polymer-cement analyses:
Polymer-Cement Composite Synthesis
Polymer-Cement Interactions by Atomistic Simulat...
This report describes a comprehensive review of 49 existing supercritical geothermal wells to inform future geothermal drilling attempts and avoid previous failure points and understand material and testing limitations, while collating information gathered in a publicly accessible...
NREL, as part of the Play Fairway Analysis (PFA) Retrospective and with assistance from PFA PIs, completed GeoRePORTs for the sites identified in Phases 1&2 of the DOE PFA projects.
The GeoRePORT (geothermal resource portfolio optimization and reporting technique) uses two factor...
