Abstract
In this paper we research the response of carbonates dissolution when interacting with carbon dioxide in the seismic wave fields in a fractured-porous reservoir. We numerically estimate the change of limestone physical properties due to CO2 sequestration based on the analysis of samples CT-scans. Obtained estimations is then used to model a poroelastic material, which we use as fracture-filling material in statistically generated fractured porous fluid-saturated media models. A numerical modeling of wave propagation is performed to estimate a velocity dispersion and attenuation caused by a wave-induced fluid flow.
