Project Title Carbonation Mechanism of Reservoir Rock by Supercritical Carbon Dioxide
Project Type / Topic 1 Laboratory Call for Submission of Applications for Research, Development and Analysis of Geothermal Technologies
Project Type / Topic 2 Supercritical Carbon Dioxide / Reservoir Rock Chemical Interactions

Project Description Supercritical CO2 is currently becoming a more common fluid for extracting volatile oil and fragrance compounds from various raw materials that are used in perfumery. Furthermore, its use as a heat transmission fluid is very attractive because of the greater uptake capability of heat from hot reservoir rock, compared with that of water. However, one concern was the reactivity of CO2 with clay and rock minerals in aqueous and non-aqueous environments. So if this reaction leads to the formation of water-soluble carbonates, such formation could be detrimental to the integrity of wellbore infrastructure.
