Abstract
The aim of this thesis is to use digital rock physics for understanding flow through porous media. Pore-scale simulations were conducted using the Finite Volume method to solve the Navier-Stokes equations, and the Volume of Fluid method for capturing interface.
A workflow is provided, in which primary drainage simulations are performed in order to establish initial water saturation. Then, secondary imbibition simulations are performed mimicking viscosity ratios found in thermal recovery processes involving hot water and heavy oil.
Through these simulations, pore-scale events such as Haines jumps, oil ganglia mobilization, fingering and oil stripping in high shear flows are identified.
This research discusses the capabilities and limitations of the Volume of Fluid method, and through the simulation results, important insights are provided in regards to the mechanisms of oil recovery through steam or hot water injection and on the balance of viscous and capillary forces in immiscible displacements.
