Abstract

WE PRESENT PORE SCALE MODELING AND SIMULATION OF SOLUTE TRANSPORT IN HETEROGENEOUS POROUS MEDIA UNDER UNSTEADY STATE CONDITIONS. THE GOAL OF THIS PAPER IS TO INVESTIGATE THE EFFECT OF PORE SPACE MORPHOLOGY AND MOBILITY RATIO ON SOLUTION TRANSPORT PROCESSES. MODELING OF SOLUTE TRANSPORT IS USEFUL IN VARIETY APPLICATIONS INCLUDES SIMULATING CONTAMINANT TRANSPORT IN AQUIFERS, DETERMINING THE POTENTIAL DANGER DERIVED FROM UNDERGROUND NUCLEAR WASTE DISPOSAL AND MODELING MISCIBLE INJECTION TO OBTAIN HIGHER OIL RECOVERY IN HYDROCARBON RESERVOIRS. ONE IDEALIZATION OF A POROUS MEDIUM IS TO CONSIDER IT AS A NETWORK, AND THEN A TWO DIMENSIONAL (2- D) PORE NETWORK OF INTERCONNECTED PORES WITH DISTRIBUTED EFFECTIVE RADII IS USED AS A MODEL OF THE POROUS MEDIA. ALONG EACH BOND ADVECTIVE-DISPERSIVE TRANSPORT OCCURS WITH COMPLETE MIXING OF SOLUTE AT PORES. IN THIS MODEL FIRST THE PRESSURE EQUATION IS SOLVED AND THEN THE CONCENTRATION DISTRIBUTION IS DETERMINED USING THE CONVECTIVE-DIFFUSION EQUATION (CDE) FOR EACH PORE IN THE NETWORK. THE RESULTS SHOW THE EFFECT OF HETEROGENEITY OF THE NETWORK, PORE SIZE DISTRIBUTION (PSD) AND MOBILITY RATIO ON VISCOUS FINGERING FORMATION, BREAKTHROUGH TIME, RECOVERY FACTOR (RF) AND LONGITUDINAL DISPERSION. THE RESULTS OF MONTE CARLO SIMULATION SHOW THAT BY INCREASING THE HETEROGENEITY OF THE NETWORK THE FINGERING FORMATION, BREAKTHROUGH TIME AND LONGITUDINAL DISPERSION WOULD INCREASE WHILE THE RF DECREASE. ACCORDING TO THE RESULTS, THE LONGITUDINAL DISPERSION DEPENDS ON THE NETWORK SIZE AND WILL INCREASE GRADUALLY WITH ITS INCREASE. ALSO THE INCREASE OF THE MOBILITY RATIO WILL DECREASE THE BREAK THROUGH TIME AND INCREASE FINGERING FORMATION.
