Earth Model
In partnership with Seequent an interactive viewer of the earth model of the Milford Site and surrounding area was developed using Leapfrog Geothermal. The datasets represent the subsurface, well locations, and microseismicity from the 2020 stimulation of well 16A(78)-32.
The earth model is best viewed on a desktop computer (not a tablet or smartphone).
Earth modeling data are in SI units and in UTM, Zone 12N, NAD83, NAVD88 referenced coordinates.
Utah FORGE Site data are available on the Geothermal Data Repository.
Modeling and Simulation Community Updates
The Utah FORGE Modeling and Simulation Forum has been created to serve as a means to communicate our role, as the Utah FORGE Modeling Team, in the research and development of the Utah FORGE site. It is a recurring meeting called the “Utah FORGE M&S Community Update” – a venue where the Utah FORGE modeling team and the modeling community can come together to discuss our efforts, successes, and challenges.
With the recent finalization and kickoff of the Solicitation 2020-1 awardee projects, the Utah FORGE Modeling and Simulation Community has greatly expanded! Every so often we ask one or two research teams to give an update on their progress and discuss any issues they (or anyone else for that matter) may be having. In 2023 it was a recurring monthly meeting held on every 3rd Wednesday of each month at 11 am MST.
New schedule for 2024 will be announced soon!
A one-time registration is required to attend
By registering, you also agree to receive informational emails about Utah FORGE M&S Community Monthly Update meetings.

Numerical Modeling
A numerical implementation of the conceptual and earth models has been developed of the FORGE reservoir and surrounding area to estimate the spatial distribution of native state pressure, temperature, and stress conditions. The primary goal of this effort was threefold.
- Incorporate detailed 3D parameter distributions and complex boundary conditions identified from characterizing the site.
- Better understand the spatial distribution of stress and how it may influence reservoir stimulation.
- Establish a reference (or baseline) set of parameter and property distributions that can be used among the team (and modeling community at large) to ensure consistency and comparability of simulation results.
The data and results included here are from the reference models completed in November 2019, at the approximate end of Phase 2. A complete report on the Phase 2 Modeling and Simulation can be found here.
Native State Modeling
Reservoir Properties
Initial reservoir properties used in the native state model were taken directly from characterization data when possible. In many cases, a range of possible values were available, and the mean or median was used, with the values being adjusted within the measured range during model calibration. In all cases, uniform reservoir properties are used within the alluvium. For the granitoid, heterogeneous property distributions are applied where appropriate and data are available. Tables below summarize the property values used. These are the “reference” values for the current state of FORGE.
