Résumé(Sommaire disponible en anglais seulement)
A geostatistical method is presented to determine the absolute horizontaland vertical effective permeabilities at the reservoir block scale from coresupport-scale values required for 3D reservoir flow simulations. The key element of the geostatistical model is the definition of block support-scalepermeabilities as the spatial power average of core-support valuespermeabilities as the spatial power average of core-support values over thevolume of a reservoir gridblock. Block support-scale permeabilities are thenfound to be a function of the permeability permeabilities are then found to bea function of the permeability variogram, the averaging volume, and apower-averaging constant, which is derived separately for horizontal andvertical flow with a numerical approach. The application of the proposed methodrequires that core-support values be available within each reservoir block.These values are generated with the technique of conditional simulation. Thistechnique provides simulated values reproducing the actual core data at sampledlocations and their statistical properties. The approach developed for thedetermination of permeability input to full-field simulators is demonstrated byan application to the Crystal Viking field "H" pool in Alberta.
