Abstract
In this study, a static local @grid refinement@ technique is incorporated into three numerical simulation models to test the technique's performance in modeling impermeable flow barriers. Several faulted systems are examined to test the effectiveness of the local grid refinement technique as compared to a coarse grid system, a fine grid system and a conventionally refined grid system. The local grid refinement method is applied to three numerical models: a single-phase slightly compressible flow simulator, a single-phase compressible flow simulator, and a three-phase black oil simulator. Compared to the fine grid system, the locally refined grid system offers a decrease in computational time with a significant improvement in accuracy over the coarse grid results.
