This is a report that describes the modelling of fracture nucleation and propagation in the near-wellbore region to understand the relationship between in situ stress and fracture patterns. A novel phase field formulation is described here, which represents fractures as a diffuse ...
This report describes minifrac tests conducted in the 16B(78)-32 well at the Utah FORGE site to characterize subsurface stresses, including the magnitude and orientation of the minimum and maximum horizontal stresses and the magnitude of the vertical stress. A minifrac test was co...
This report discusses the results of research on the ability to create and/or reactivate and subsequently sustain fracture systems which are strongly influenced by complexly coupled mechanical (M) and chemical (C) processes in reservoirs forced from equilibrium by hydraulic stimul...
This dataset provides an empirical three-dimensional P and S-wave velocity model covering a 30 x 30 km area and extending to 10 km depth around the Cape Modern EGS and Utah FORGE sites. It incorporates three-dimensional topography and a sediment/basement contact derived from geoph...
This dataset contains distributed acoustic sensing (DAS) microseismic event triggers (raw waveforms) recorded during the 16A-16B stimulations conducted at the Utah FORGE site in April 2024. The dataset consists of raw waveform data provided in nanostrain rate units, accompanied by...
This document provides a pre-drill prognosis for the Gold 2-P well at Fervo's Cape Project site, highlighting temperature and lithology projections. Elements include well trajectory schematics, a temperature-depth profile, and geologic cross sections. The temperature is estimated...
Provided here is a set of presentation slides detailing stress-dependent permeability in FORGE granitoid fractures and how fracture slip affects permeability. It outlines empirical correlations between permeability, stress, and fracture aperture, emphasizing that mechanically clos...
Report on possible geodetic signature of the 3 stimulations in April 2022 as well as a comparison with existing InSAR data gathered over the site before, during, and after the stimulation. In geothermal production it is important to understand the existing stress field and the cha...
This report details the work Welltech has done to provide true zonal isolation of the geothermal reservoir across multiple zones and cycles, enabling effective stimulation and repeated treatments of selected zones. The project included a literature review, small-scale experimentat...
This is a set of data related to the stimulation program at Utah FORGE well 16A(78)-32 during April, 2022. This includes daily reports, 1 second Pason data, tracer data, and shear stimulation data and information including a report of an evolving prognosis for the stimulation oper...
This report contains the results of research conducted to make measurements in the FORGE wells to map flowing fractures and estimate their flow magnitudes in real time. Implementation of the project had two substantial goals: (1) to locate flowing fractures at FORGE and estimate t...
This dataset contains all well logs from Utah FORGE well 16A(78)-32. This includes the mud log, Sanvean Technologies logs, and Schlumberger logs. Please see the file descriptions below for information about each log.
This dataset includes survey data, drilling data, daily reports, summaries of daily operations, and rig photos from the drilling of Utah FORGE well 16A(78)-32, which is a highly deviated deep well. It was completed 60 days ahead of schedule.
Rig move in began 10/22/2020 and dril...
This is an analysis of the pressure falloff in stage 1 fracture stimulation of FORGE well 16A(78)-32. The objective of this research is to understand the information content of the well stimulation data of FORGE Well 16A(78)-32. The Stage 1 step-rate test, a variant of the classic...
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 incl...
The included report outlines the creation of three 3D resistivity models that will be used to determine the sensitivity of EM measurements for the hypothetical stimulated reservoir at FORGE as well as for EM survey design. FORGE project 3-2535 is planning on using a casing source ...
This report describes the modifications made to the Vertical Electromagnetic Profiling (VEMP) borehole tool, currently on loan to Lawrence Berkeley National Laboratory (LBNL) from Japan's Geothermal Energy Research and Development Co., Ltd. (GERD), during its refurbishment. It inc...
This data archive includes the relocated microseismic event catalog from distributed acoustic sensing (DAS) acquisition conducted during the 16A-16B circulation tests that took place in July 2023. These results update the catalog presented in GDR 1613 (the preliminary catalog, lin...
This dataset includes an Excel file with the results of direct shear tests to investigate the mechanical and geophysical response of saturated joints. Tests were conducted on induced tension-fractured Sierra White granite joints in a custom water pressurized chamber. The preparati...
New high-quality tensor MT data at 122 sites, including the vertical magnetic field and utilizing ultra-remote referencing, have been acquired over the Utah FORGE project area. The results will be used to delineate the densities of faults and fractures in crystalline basement rock...
This dataset encompasses simulations of strain signatures from both hydraulically connected and "near-miss" fractures in enhanced geothermal systems (EGS). The files and results are presented from the perspective of digital acoustic sensing's (DAS) potential to differentiate the t...
This submission houses the companion code for the manuscript by Zhengfa Bi (Lawrence Berkeley National Laboratory) and Nori Nakata (Lawrence Berkeley National Laboratory; MIT). Both the companion code and manuscript are included in the resources section of this submission.
