Utah FORGE 5-2565: Evolution of Permeability and Strength Recovery of Shear Fractures Under Hydrothermal Conditions - 2024 Annual Workshop Presentation

This is a presentation on the Evolution of Permeability and Strength Recovery of Shear Fractures Under Hydrothermal Conditions by United States Geological Survey, presented by Tamara Jeppson. This video slide presentation, by the USGS, discusses the determination of how thermal, hydrologic, mechanical, and chemical (THMC) processes affect the sustainability of fracture networks in geothermal reservoirs. This includes (1) the qualification of rates of change of fracture properties, (2) the parameterization of modes of reaction, (3) the development of micromechanical and empirical fracture models, and (4) extended THMC models for laboratory- and reservoir-scale models. This presentation was featured in the Utah FORGE R&D Annual Workshop on August 15, 2024.

本报告由美国地质调查局（United States Geological Survey）的Tamara Jeppson女士主讲，主题为“水热条件下剪切裂缝渗透性和强度恢复的演变”。该视频幻灯片演示报告由USGS提供，探讨了热力学、水文学、力学以及化学（THMC）过程如何影响地热储层中裂缝网络的可持续性。内容涵盖以下四个方面：（1）裂缝特性变化速率的评估，（2）反应模式的参数化，（3）微观力学和经验裂缝模型的发展，（4）实验室及储层尺度模型的扩展THMC模型。本报告于2024年8月15日举行的犹他FORGE研发年度研讨会上展出。
