Data from injection-driven fault reactivation experiments on faulted sandstone

Human activities involving subsurface fluid injection projects, such as geothermal energy recovery and/or gas storage (CO<sub style="background-color:rgb(255, 250, 234);">2</sub>, H<sub style="background-color:rgb(255, 250, 234);">2</sub> or methane), are widely acknowledged to occasionally cause earthquakes. We performed laboratory tests on highly permeable Red Felser sandstone containing a simulated geological fault to investigate effect of injection rate and pattern on fault movement. Triaxial injection-driven fault reactivation tests were performed alongside with passive acoustic measurements. This dataset contains mechanical data along with passive acoustic data from injection-driven fault reactivation experiments on faulted sandstone. Also python script used for analysis is provided. A detail information about the data is described within the readme file.

涉及地下流体注入工程的人类活动——例如地热能源开发以及（二氧化碳、氢气或甲烷等）气体储存——已被广泛证实偶尔会引发地震。本研究针对含模拟地质断层的高渗透性雷德费尔砂岩（Red Felser sandstone）开展实验室测试，以探究注入速率与注入模式对断层运动的影响。实验同步开展了三轴注入驱动断层再活化测试与被动声学测量。本数据集收录了含断层砂岩在注入驱动下开展的断层再活化实验所产生的力学数据与被动声学数据。同时附带了用于数据分析的Python脚本。数据集的详细说明详见自述文件。
