文摘
- •
Two-phase subsurface flows with capillary heterogeneity are studied.
- •
A new method is developed to upscale relative permeability and capillary pressure.
- •
The procedure is tested on a numerical model of CO2 injection into an aquifer.
- •
The method provides accurate results and clearly improves upon simpler treatments.
- •
Upscaled properties are sufficiently robust for reuse in related simulations.
