Implication

An invasion percolation study demonstrates the effects of pore coupling on gas trapping in porous media, suggesting optimization strategies for fluid injections.

Key Points

This research aims to analyze how cyclic fluid injections affect saturation hysteresis in porous media using a modified invasion percolation algorithm.
Developed a modified invasion percolation algorithm with a pore coupling coefficient.
Simulated cyclic fluid displacements in porous media to observe saturation changes.
Explored the influence of pore coupling strength on displacement morphology.
Displacement morphology and saturation hysteresis are significantly modified by pore coupling strength.
Phase diagrams indicate that cyclic injections enhance residual gas trapping under certain conditions.
Identified relationships between the pore coupling coefficient and key physical parameters like wettability and porosity.
