AB - Carbon dioxide is currently being injected into saline aquifers and depleted oil and gas reservoirs with both enhanced oil recovery (EOR) and carbon capture and storage (CCS) purposes. The injected CO2 in contact with the reservoir fluids creates an acidic mixture that can potentially react with the host rock causing changes in the petrophysical properties of the reservoir. From the experimental point of view much work has been recently published in the scientific literature about the impact of acidic brine in carbonate reservoirs. These laboratory results indicate that strong rock-fluid interactions may occur, however, pore-scale models capable of predicting how the petrophysical changes associated with these reactions can be related to transport properties are yet to be developed. The recent increase in computational power and tomographic capability made possible the acquisition of high resolution images of heterogeneous carbonates that are very suitable to study in detail the flow and transport properties of such rocks. In this paper we demonstrate how micro-CT images of carbonate rocks can be used to model reactive transport at the pore scale. We apply a particle tracking algorithm based on a pore-scale streamline tracing method to simulate carbonate dissolution.
