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. Geochemical modeling can be useful in providing a first-hand evaluation of potential of mineral precipitation along the different reaction paths. We developed geochemical models for injecting four different relevant water compositions in the FORGE Utah geothermal reservoir through well 58-32. Results and discussions related to this work are presented in this technical report.

This is a compilation of logs and data from Well 82-33 in the Roosevelt Hot Springs area in Utah. This well is also in the Utah FORGE study area. The file is in a compressed .zip format and there is a data inventory table (Excel spreadsheet) in the root folder that is a guide to the data that is accessible in subfolders.

This dataset contains results from four fluid injection experiments at 24 C, 69 C, 111 C, and 140 C using a triaxial loading apparatus ("Temco"). Tests were conducted on a Utah FORGE granite sample with a 30 degree inclined fracture. Confining pressure was maintained at 10 MPa, while shear stress was reduced to create a zero-displacement condition, which means the shear stress decreases continuously. Pore pressure was increased stepwise at 300 kPa every six minutes to simulate injection. Temperature was rapidly raised by voltage heating and then stabilized. Data are provided in spreadsheet format, with one file per temperature. Each file contains upstream and downstream measurement sheets with columns for pressure, flow rate, displacement, and time, with units specified in the headers.

This is a presentation on the Experimental Determination and Modeling-Informed Analysis of Thermo-poromechanical Response of Fractured Rock for Application to Utah FORGE project by the University of Oklahoma, presented by Dr. Ahmad Ghassemi, McCasland Chair Prof. The project objective is to improve understanding and control of coupled thermo-poromechanical (or thermo-hydro-mechanical- TPM) processes in reservoir development, and to study any role in interpretations of the fracture closure. This presentation was featured in the Utah FORGE R&D Annual Workshop on September 8, 2023. The workshop provided a valuable opportunity to explore the progress made in each of the 17 Research and Development projects funded under Solicitation 2020-1 which aim to enhance our understanding of the crucial factors influencing the development of Enhanced Geothermal Systems (EGS) reservoirs and resources.

This dataset contains experimental data from fluid injection experiments conducted to investigate the influence of temperature on fracture seismicity. The experiments were performed on granite samples from Utah FORGE. The samples were prepared with a 30-degree inclined fracture and subjected to controlled stress and temperature conditions. Data were collected under three distinct temperature settings: 24 C, 78 C, and 137 C. During the experiments, a constant confining pressure of 10 MPa and a constant shear stress at 80% of the shear strength of the sample were maintained. Pore pressure was incrementally increased at a rate of 300 kPa every three minutes to simulate fluid injection. Temperature was raised rapidly and then stabilized for the duration of each test. The dataset includes shear stress and displacement measurements under each temperature condition, along with supplementary figures illustrating the experimental setup and time-series plots of pressures and temperature.
