CONNECT-UpGrid is Petrel plug-in for upscaling utility. It performs the optimum vertical upscaling design by minimizing the error on the pressure while combining vertical layers.
Upscaling Challenge for Upgriding
Why do you need to use CONNECT-UpGrid
CONNECT-UpGrid in conjunction with CONNECT-TransMod program maintains the heterogeneity of the fine scale model within the coarse scale model. With these two program you get 90% accuracy of your fine scale dynamic behavior with 10% of your model size, which translates into 100 times faster flow simulations.
Going from geological model with millions of cells to a simulation model requires a careful upscaling of the fine scale grids so that dynamic performance of the geological model is preserved. Using proportional upgridding would result in combining layers which will have different petrophysical properties. CONNECT-UpGrid uses a new algorithm which allows the combination of layers such that the pressure profile at fine scale is preserved. The layers – which have similar pressure distributions – are combined first, and the layers with distinct pressure profiles are isolated. In addition, depending on the mobility ratio, the layering is adjusted. By preserving the dynamic behavior, the resulting upscaled model is able to reproduce the behavior of the fine scale model with 10% of the effort. In addition to combining the layers correctly, the program also is able to provide the guidelines in terms of optimum number of layers needed to preserve the fine scale, dynamic, behavior.
