Abstract
To appreciate the changes in porosity in the carbonate rocks a simple, one dimensional model of fluid flow and dissolution reaction has been elaborated. The results indicate how porosity changes evolve during replacement of the original saturated solution by a cold undersaturated fluid injected into the carbonate aquifer. Such modeling, with hydraulic feedback via porosity - permeability relationship, could be potentially used to recognize the sites of unfavorable development of porosity.
