Abstract
Simple, efficient, and stable static and dynamic local grid refinement procedures for multi-dimensional, multi-phase reservoir problems are developed and tested via isothermal reservoir simulations. The proposed technique uses the methodology developed by Brandt with some modifications and simplifications. First, a complete solution is obtained using a coarse grid (also referred to as a base or fundamental grid). This solution determines the preliminary primary variable distribution in the entire domain, and provides input for localized high curvature, high gradient fine grid regions. Second, Dirichlet type boundary conditions are assigned to the fine grid at the coarse-fine node interfaces. Flow equations are then resolved only within the boundaries of the fine grid.
