CO2-induced salt precipitation test in sandstone

Here we present the dataset collected during a CO2 flow-through test using a synthetic sandstone of high porosity and permeability, originally saturated with high salinity brine, performed under realistic shallow reservoir conditions stress. During the test, we collect geophysical data (elastic and electrical properties) which record petrophysical variations in the rock related to the precipitation of salt, induced by a continuous CO2 flow through the sample.

本文呈现的数据集来源于一项CO₂渗流试验（CO₂ flow-through test）。该试验采用高孔隙度（porosity）、高渗透率（permeability）的人造砂岩（synthetic sandstone），其初始饱和高盐度盐水（high salinity brine），并在真实浅层储层应力条件下开展。试验过程中，我们采集了地球物理数据（geophysical data），包括弹性特性（elastic properties）与电学特性（electrical properties），这些数据记录了岩石中与盐沉淀（salt precipitation）相关的岩石物理变化（petrophysical variations）——该盐沉淀由CO₂持续渗流样品所诱发。
