Flow rate through carbonate rocks is known to have a major impact on carbonate dissolution and permeability evolution. Acidic fluids and large flow rate will lead to a single channel connecting inlet and outlet of a core sample, while very small flow rate will result in front dissolution at the inlet of the sample. Golfier et al. (2002) takes into account these two variables by mapping the expected channel architecture as a function of the Damköhler and Péclet numbers. In this study we offer effective stress as a third variable influencing carbonate dissolution by experimentally and numerically investigating its effect on homogeneous Indiana limestone. This comparative study confirms that the prime variable for carbonate dissolution is related to the velocity of the fluid at the inlet of a sample. In addition, we found that effective stress also plays a significant secondary role as a permeability and calcium dissolution stimulator.
