Replication Data for: Experimental investigation of natural fracture stiffness and flow properties in a faulted CO2 bypass system (Utah, USA)

The dataset provides relevant data from experimental work in order to calculate fracture permeability and stiffness (closure) as presented in the publication; Experimental investigation of natural fracture stiffness and flow properties in a faulted CO2 bypass system (Utah, USA). Fracture stiffness and flow properties have been measured in the laboratory using naturally fractured fault rock samples from the Little Grand Wash fault, Utah, USA. We compare fracture closure and related flow change during isotropic loading of two fractures which have been subject to various amounts of paleo-reactive flow. The two tested fractures are described as (i) a small-aperture fracture (0.1 mm) with negligible geochemical alterations of the fracture surface and (ii) a large-aperture fracture (0.53 mm) where precipitates are observed on the fracture surface.

本数据集提供了源于实验研究的相关数据，旨在计算依据出版物所呈现的裂缝渗透性和刚度（闭合度）；对美国犹他州二氧化碳绕行断层系统中的天然裂缝刚度和流动特性进行了实验研究。实验室中已对来自犹他州小格兰德瓦什断层的天然裂缝断层岩样进行裂缝刚度和流动特性的测量。我们比较了在受到不同古反应流量的影响下，两种裂缝在等向加载过程中的裂缝闭合度及相关流动变化。两种测试裂缝的描述如下：（i）一个小开口裂缝（0.1毫米），裂缝表面地质化学变化可忽略不计；（ii）一个大开口裂缝（0.53毫米），在裂缝表面观察到沉淀物。
