Use of lithofacies-scale models in reservoir appraisal and simulation

A lithofacies-scale modeling tool, SBEDTM, has been used to create multiple realizations of facies heterogeneity at the sub-metre to metre scale. These lithofacies models have been used in a range of reservoir studies, including formation appraisal, geological modeling, singlephase flow upscaling and multiphase flow upscaling. This paper summarizes the multi-scale geological modeling approach used in this work and the potential value of the approach for other reservoir appraisal and modeling studies.
