Utah FORGE Project 3-2535: Building a 3D Resistivity Model for Simulation and Survey Design of EM Measurements

Description

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 EM method for detecting and imaging a deep localized stimulated fracture zone at the Utah FORGE site. Details on other stages of the project are included in the linked GDR submissions below.

21 This short report details and tests the workflow that will be used to simulate steel well casings in deviated production/extraction boreholes at at the Utah FORGE site. Boreholes will be electrically energized and will serve as data sources for future proposed electromagnetic borehole surveys, which will be used to delineate/estimate the size and porosity of the main FORGE stimulated reservoir. https://gdr.openei.org/submissions/1433

33 This report outlines the creation of the 3D resistivity models with Section 2 below covering the creation of the baseline model, and Section 3 the inclusion of a stimulated reservoir zone within the baseline model. https://gdr.openei.org/files/1436/FORGE_milestone_4p1_11_29_2022_FIN.pdf
33 The results of the modeling / survey design study using this model will be employed in a GO / NO GO decision point on whether to continue with the project. This presentation shows the resistivity models that will be employed in the survey design phase of our project to determine the magnitude of fields and how much sensitivity there is to the proposed FORGE stimulated zone when the injection well (16a) is energized with an electric current source connected at the surface as well as other locations down hole above the deviation point, and 3 component magnetic field measurements are made with the VEMP tool in Monitoring wells 58B and 78B located a few hundred meters away from the stimulation. https://gdr.openei.org/files/1436/FORGE_Project_3D_Resistivity_Model.pdf
