摘要
In the management of an oil field, the creation of a highly detailed fine-scale model to properly represent the key reservoir heterogeneities is important. This model better represents the main reservoir features but remains a significant challenge for dynamic reservoir simulations with impractically high computational costs, even for single numerical simulation runs. Therefore, the scaling up of a highly detailed model is a crucial step in reservoir engineering studies to enable field-scale simulation runs within a time-frame compatible with the needs of the industry. Upscaling must be carefully performed because it can introduce significant errors and bias to the numerical models due to truncation errors and the smoothing of sub-grid heterogeneities.
