DR350-Dynamic reactor for rock-CO2-brine interactions

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.

Benefits

* Realistic simulation of CO₂, brine, and rock interactions under underground storage conditions in dynamic mode.
* Ability to assess changes in rock permeability at different saturation levels, which is crucial for predicting CO₂ storage behaviour
* Integration with advanced analytical tools like XRD, SEM, and EDS to detail rock mineralogical changes after CO₂ exposure, helping to understand geochemical reactions in the storage reservoir.
* Can be used with rock and cement samples
