Utah FORGE 5-2419: Seismicity-Permeability Relationships Probed via Nonlinear Acoustic Imaging - Workshop Presentation

This is a presentation on the Seismicity-Permeability Relationships Probed via Nonlinear Acoustic Imaging project by Pennsylvania State University, presented by Derek Elsworth. The project's objectives were to explore controls and acoustic signatures of aseismic through seismic evolution of friction-stability-permeability relationships on fractures in shear-reactivation, link this reactivation to key features of the pre-existing stress state, and upscale these indexes to reservoir scale to drive successful reservoir stimulation. 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.

此为宾夕法尼亚州立大学Derek Elsworth教授关于通过非线性声学成像探查地震性与渗透性关系的研究项目报告。该项目旨在探讨剪切再活化裂缝中摩擦稳定性-渗透性关系在地震演化过程中的控制因素及声学特征，并将这一再活化过程与先前应力状态的关键特征相联系，进而将这些指标升级至储层规模，以推动储层刺激的成功实施。该报告于2023年9月8日在犹他州FORGE研发年度研讨会上展出。此次研讨会为深入探讨在2020-1号招标下资助的17个研发项目取得的进展提供了宝贵机会，这些项目旨在深化我们对增强型地热系统（EGS）储层及资源开发中关键影响因素的理解。
