Coarse-scale Modeling of Flow in Gas-injection Processes for Enhanced Oil Recovery

摘要

Subsurface formations that arise in the simulation of gas-injection processes for enhanced oil recovery may exhibit geometrically complex features with complicated large-scale connectivity. They must be included in simulations of flow and transport because they can fundamentally impact simulation results. However, to reduce computational costs, simulations are generally performed on grids that are coarse compared to the given geocellular grids, so accurate upscaling is required.
