This dataset contains trace element concentrations from fluid samples collected during the August-September 2024 circulation test at Utah FORGE. Samples were taken from injection well 16A(78)-32, production well 16B(78)-32, and monitoring well 58-32 on four dates between August 16 and September 3, 2024. Samples were unfiltered and not acidified before being submitted to and analyzed at the Brigham Young University geochemistry lab. Data are organized by well type and date.

This data includes a document that describes the effort to collect and analyze water and gas samples from deep Utah FORGE wells 16A(78)-32, 58-32, 56-32 and 78B-32 along with additional pdf files showing ThermoChem's analyses attached as an appendix.

This report provides a first-order assessment of the producible energy from the Utah FORGE EGS reservoir, based on stimulation and circulation testing in 2024. The assessment is based on a stored heat calculation for a cylindrical volume of stimulated hot dry rock enveloping the deviated legs of wells 16A(78)-32 and 16B(78)-32, and conservative estimates for recoverable energy. It also shows the potential for increased power production with deepening of the reservoir. The results are compared with the power produced during the 27-day circulation test in August-September 2024.

This dataset contains core-flood experimental results from the Utah FORGE project, generated through laboratory tests at Lawrence Livermore National Laboratory. The experiments were conducted at temperatures of 100C and 200C using core samples from the 16A(78)-32 well. The primary objectives of these tests were to determine the change in calculated hydraulic fracture and permeability over time, under constant confining pressure, in predominantly constant flowrate conditions, while monitoring effluent chemistry as a function of time. The dataset includes measurements related to elapsed time, sample pH, elemental concentrations, and pressure conditions at different core depths. Additional data captures inlet and outlet pressures, pump flowrate, brine temperature, reactor pressure, and calculated hydraulic parameters.

Geochemical data for cold groundwaters and produced geothermal fluids around the Utah FORGE site. The data is compiled into four tables in the attached Excel File. Table 1 is a compilation of compositions (anions, cations, weak acids, oxygen, hydrogen, and carbon isotopes) for cold groundwaters and produced geothermal waters in the Milford valley, Utah. Table 2 is a compilation of noble gas (He, Ne, Ar) and He and Ne isotopic compositions for cold groundwaters and produced geothermal waters in the Milford valley, Utah. Table 3 provides values for calculated advective and diffusive fluxes of helium. Table 4 provides values of calculated subsurface stored heat between the Opal Mound fault and the Utah FORGE site, which are related to volumes of recently solidified magmatic heat sources.
