Utah FORGE 5-2557: Fluid and Temperature in Fracture Mechanics and Coupled THMC Processes - Workshop Presentation

This is a presentation on the Role of Fluid and Temperature in Fracture Mechanics and Coupled Thermo-Hydro-Mechanical-Chemical (THMC) Processes for Enhanced Geothermal Systems project by Purdue University, presented by Distinguished Professor of Physics & Astronomy, Laura J. Pyrak-Nolte. The project's objective was to develop and validate a macroscopic model that accounts for local deformation/frictional behavior, seismic/aseismic behavior, chemical reactions, and determine the adequacy of classic Coulomb failure vs. rate-and-state friction. This presentation was featured in the Utah FORGE R&D Annual Workshop on September 8, 2023. The workshop provided a valuable opportunity to explore the progress made in each of the 17 Research and Development projects funded under Solicitation 2020-1 which aim to enhance our understanding of the crucial factors influencing the development of Enhanced Geothermal Systems (EGS) reservoirs and resources.

本报告由普渡大学物理与天文学系资深教授劳拉·J·皮拉克-诺尔特（Laura J. Pyrak-Nolte）主持，深入探讨了流体与温度在断裂力学以及耦合热-水-机械-化学（THMC）过程中的作用。该项目旨在构建并验证一个宏观模型，该模型能够考虑局部变形/摩擦行为、地震/非地震行为、化学反应等因素，并评估经典库仑破坏与速率和状态摩擦的适用性。该报告作为2023年9月8日犹他FORGE研发年度研讨会的一部分，研讨会在探讨资助于2020-1号征求令下资助的17项研发项目进展方面提供了宝贵的机会，这些项目旨在深化我们对增强型地热系统（EGS）储层和资源发展关键影响因素的理解。
