Multi-Scale Lattice Boltzmann Simulation of Carbonate Rock Dissolution in Acidizing Process, Ph.D. Dissertation Sharif University of Technology ; Ayatollahi, Shahabodin (Supervisor) ; Jamshidi, Saeed (Supervisor) ; Raoof, Amir (Co-Supervisor)
Abstract
During the Acidizing process in oil and gas reservoirs, the injected acid reacts with the rock grains, changes the rock pore structure and affects the flow conditions. Due to the presence of a large concentration gradient at the vicinity of the rock grains and the continuous changes in rock-fluid interfaces of the porous medium, the continuum assumption has been remained debatable for the effective local mass transport and effective molecular diffusion coefficients and the porosity-permeability relation in the continuum scale modeling of this process. Therefore, the need for pore scale modelling is evident. The novelty of this study relies in adapting the grid refinement method on the...
