Pore-Scale Dynamics of Multiphase Reactive Transport in Water-Wet Carbonates under CO2-Acidified Brine Injection: Dissolution Patterns and Reaction Rates

Experimental Study of CO2-Acidified Brine Injection in Ketton Limestone with Residual Hydrocarbon This dataset contains time-resolved X-ray microtomography (micro-CT) imaging data investigating the dissolution dynamics of Ketton limestone under multiphase condition. The study focuses on the context of Carbon Capture and Storage (CCS) in depleted reservoirs, examining how the presence of a residual hydrocarbon phase influences dissolution patterns under reservoir conditions. The data captures the complex pore-scale interactions between the rock matrix, CO2-acidified brine, and residual hydrocarbons, revealing distinct dissolution regimes driven by multiphase dynamics and flow heterogeneity.
