Utah FORGE 2-2446: Report on Laboratory Block Experiments with Six Different Combinations of Stresses and Rock Fabrics
This report documents a series of block-scale hydraulic fracturing experiments, simulating Utah FORGE conditions to investigate how different combinations of in situ stress regimes, well orientations, and thermal stress conditions influence fracture initiation and propagation. The report describes the experimental setup designed to replicate Utah FORGE conditions, then details an innovative testing protocol, including the examination of post-peak pressure records and the improved wellbore temperature measurement setup. This work was conducted as part of Utah FORGE Project 2-2446, "Closing the Loop Between In-situ Stress Complexity and EGS Fracture Complexity."
