The Impact of Scale of Measurement on Integrated Petrophysical Interpretations

In geocellular reservoir modelling, the final vertical increment scale of the grid size is a compromise between the preservation of observed reservoir heterogeneities and what is practical for simulation purposes in terms of the total number of active cells in the dynamic model. The challenge is to preserve the heterogeneity of the initial petrophysical rock property modelling throughout the upscaling process without introducing an artificial bias to the observed property trends.
