Description
Mineral dissolution during CO2 geological storage significantly alters the structural integrity and long-term storage capacity of reservoirs. This study investigates the reactive transport and mineral dissolution processes induced by CO2-saturated brine injection across three porous rocks with distinct pore-space geometries. Utilizing micro-CT images, we employ a micro-continuum method coupled with an improved Volume of Solid (VoS) approach to simulate the evolution of the pore space. The study focuses on the reaction-limited dissolution regime, specifically exploring the relationship between the exposed surface area and the effective dissolution rate across a range of Péclet numbers. Our analysis quantifies how initial pore-space geometries and emergent dissolution morphologies govern the evolution of this relationship.
