Description

The DR350 is a multifunctional flow system designed for CO2 sequestration tasks and dynamic studies of CO2-brine-rock interactions using a sleeved coreholder. This dynamic reactor can simulate the actual flow conditions of injected CO2 and its interactions with brine and rock under storage conditions. Rock permeability values can be determined when the rock is at its initial water saturation (Swi) and when it's at its residual gas saturation (Srco2). Subsequent to this conditioning phase, advanced analytical techniques, including X-ray diffraction (XRD), scanning electron microscopy (SEM) and energy dispersive spectrum (EDS) can be deployed to facilitate the identification of mineral dissolution and precipitation by comparing their properties before and after the exposure. The goal is to understand potential geochemical reactions and alterations that might occur when CO2 is stored underground in geological reservoirs and their impact on the rock porosity and permeability.
