  7. Abstract:
  8. In this work, a basic model for numerically simulating matrix acidizing in carbonate formations is developed. This model employs laboratory linear acid core-flooding data and avoids any fitting parameters. Wellbore-scale numerical simulation is based on finite-volume method with Cartesian coordination and cubic meshing. Mass transfer equations are based on fluid front tracking and the momentum transfer equation is the Navier-Stokes equation for flow in porous media. The effect of fine-scale dissolution phenomena of carbonate rocks are translated into the coarse-scale by homogenization. In this work, it is tried to achieve a simple but logical approach towards a correct simulation, avoiding illogical assumptions, fitting parameters and inaccessible experimental parameters. The presented model is validated using fine-scale simulations in large laboratory dimensions. Its ability to accurately simulate in wellbore dimensions is validated qualitatively; since fine-scale solutions with wellbore dimensions and proper field data were not available for quantitative validation. This evaluations are based on field experiments and previous observations in the literature. In the end, the shortcomings of this research are stated and what is to be done in the future
