Utah FORGE: Updated Discrete Fracture Network Model - 2025

Description

The Utah FORGE 2025 v1 DFN (fracture model) includes 131 discrete planar fractures which were identified using combined site data sets to capture flow pathways between wells 16A(78)-32 and 16B(78)-32 following stimulation activities in 2022 and 2024. It also includes stochastic fractures (radius 20-150 m) away from well control. The DFN details fracture geometry such as position, orientation, and size, but does not address hydraulic properties like aperture, permeability, or compressibility, which may vary within each fracture plane. Further information and figures illustrating various fracture subsets are available in the accompanying notes document.

57 This archive contains files for the v1 DFN (fracture model). There are two versions for local coordinates in both meters and feet. The model is in multiple file formats, including CSV, GOCAD, and ASCII .fab files. The .fab file links named fracture sets to 3D geometries and attributes like aperture and permeability defined in the .ts files. https://gdr.openei.org/files/1750/DFN%20Update%202025%20v1.zip
