...-equilibrium rate equations that simulated the delay in solvent reaching its equilibrium concentration as it dissolves or exsolves in the oil in response to changes in the pressure and/or gas phase composition. Dissolution of CH4, C3H8, and CO2 in oil and CO2 in water were considered, as was exsolution of CH4...

... experiments, conducted for different rock systems, are modeled using the fully coupled geochemical compositional simulator and the relevant permeability relationships are compared to determine the best fit with the experimental results. This study determined that simulated changes in porosity and permeability...

... Abstract The design and optimization of solvent based processes to recover heavy oil are hampered by limited data and modeling capability for mixtures of heavy oils and solvents. Phase boundaries, compositions, and physical properties such as viscosity and density are required. Here, mixtures...
