The project provides an updated Energy Return on Investment (EROI) for Enhanced Geothermal Systems (EGS). Results incorporate Argonne National Laboratory's Life Cycle Assessment and base case assumptions consistent with other projects in the Analysis subprogram. EROI is a ratio of the energy delivered to the consumer to the energy consumed to build, operate, and decommission the facility. EROI is important in assessing the viability of energy alternatives. Currently EROI analyses of geothermal energy are either out-of-date, of uncertain methodology, or presented online with little supporting documentation. This data set is a collection of files documenting data used to calculate the Energy Return On Investment (EROI) of Engineered Geothermal Systems (EGS) and erratum to publications prior to the final report. Final report is available below, or from the OSTI web site (http://www.osti.gov/geothermal/). Data in this collections includes the well designs used, input parameters for GETEM, a discussion of the energy needed to haul materials to the drill site, the baseline mud program, and a summary of the energy needed to drill each of the well designs. EROI is the ratio of the energy delivered to the customer to the energy consumed to construct, operate, and decommission the facility. Whereas efficiency is the ratio of the energy delivered to the customer to the energy extracted from the reservoir.

The data files below summarize the results from various experiments testing properties of high-temperature self-healing inorganic cement composites. These properties include cement-carbon steel bond strength, Young's modulus recovery, matrix recovery strength, and compressive strength and Yonug's modulus for cement composites modified with Pozzolanic Clay additives.

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 cement composites in three curing environments (water, alkali carbonate, brine) at 300 degC, bond strength measurements for cement/carbon steel samples, thermal shock tests, performance of healing aids. The presentation was shown during the joint SPE/GRC workshop on March 22 in San Diego, California

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 Simulations Polymer-Cements Compressive Strength & Fracture Toughness Polymer-Cements Fourier Transform Infrared Spectroscopy (FTIR) Analysis Polymer-Cements Resistance to Thermal Shock-CO2 and H2SO4 Attack Polymer-Cements Rheology Analysis Polymer-Cements Self-Repairing Permeability Analysis Polymer-Cements Scanning Electron Microscopy with Energy Dispersive X-Ray Spectroscopy (SEM-EDX) Compositional Analysis Polymer-Cements Thermogravimetric Analysis (TGA) and Total Organic and Inorganic Carbon Analysis (TOC and TIC) Polymer-Cements X-Ray Diffraction (XRD) Analysis

The data include compressive strength and Young's Modulus recoveries in steam and carbonate environments at 270 deg C for four chemically different cement composites after imposed controlled damaged.

This data set includes the daily drilling reports and Pason data for well 78B-32 and Schlumberger logs acquired after drilling completion. This well was drilled between June 27th and July 31st of 2021. Also included is raw and processed data for a variety of well data metrics including temperature, porosity, density, and sonic data. This data was taken at the Utah FORGE site as part of the Utah FORGE project.
