Abstract

Summary

This paper presents an upgraded workflow to address direct geostatistical simulations on unstructured grids. Comparing to previous approaches, this algorithm is based on a recently proposed spectral decomposition applicable to a wide class of variograms and allowing for non-stationarity. The method is encapsulated in a workflow dedicated to unstructured grids including facies modeling and hydrocarbon in place computations. The proposed methodology is able to treat any kind of grid; it takes into account the support effect and it decreases drastically the computation time compared to previous approaches based on Sequential Gaussian Simulations. The method is illustrated on a synthetic example and some results on a true case study are also provided.
