Utah FORGE 2-2439: A Multi-Component Approach to Characterizing In-Situ Stress: Laboratory, Modeling and Field Measurement - Workshop Presentation

This is a presentation on A Multi-Component Approach to Characterizing In-Situ Stress at the U.S DOE FORGE EGS Site: Laboratory, Modeling and Field Measurement project by Battelle [Columbus, OH], presented by Mark Kelley. The project's objective was to characterize stress in the Utah FORGE EGS reservoir using three methods: a laboratory rock-core stress estimation combined with a Machine Learning approach for estimation of in-situ stress from field sonic-log data, a field based in-situ measurement (min-frac) approach, and a modeling approach. This presentation was featured in the Utah FORGE R&D Annual Workshop on September 7, 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.

本报告为一项关于美国能源部FORGE EGS场地原位应力表征的多组件方法研究展示，由巴特尔公司（俄亥俄州哥伦布市）承担，并由马克·凯利先生主讲。该项目旨在运用三种方法对犹他州FORGE EGS储层中的应力进行表征：将实验室岩石芯应力估计与机器学习方法相结合，以从现场声波测井数据中估计原位应力；基于现场的现场原位测量（最小裂缝）方法；以及建模方法。本次展示于2023年9月7日在犹他州FORGE研发年度研讨会上展出。研讨会为探讨在2020-1号征求令下资助的17个研发项目所取得的进展提供了宝贵的机会，这些项目旨在深化我们对影响增强型地热系统（EGS）储层和资源开发的关键因素的认知。
