Research on immiscible flow in a heterogeneous porous media has been an active area of research, particularly due to its close relationship with hydrology and petroleum engineering. Specifically, the modelling of oil migration and non-aqueous phase liquid migration in groundwater is a major challenge due to the multi-scale heterogeneous nature of the porous media.
In this project we will develop efficient numerical method to simulate the fluid-fluid displacement process in porous media with a gradient in grain size, and gain fundamental understanding on the impacts of gravitational and capillary forces in spatially correlated porous media.
- Develop invasion percolation algorithm with consideration of capillary and gravitational forces for simulating multiphase flow.
- Construct spatially correlated porous media with grain size gradient.
- Carry out simulations to probe the effects of topological features of porous media.
- Understand the fundamental mechanisms that govern fluid-fluid displacement process in porous media.
- Gain new insights in the transitions between stable displacement and capillary fingering regimes during gravity driven multiphase flow.
- Publish the outcomes in applied engineering literature.
