Upscaling Theory and Application Techniques for Reservoir...
Qi, Dasheng
What is the physical target of upscaling in reservoir simulation? Lasseter et al. proposed that scale-up of properties should be done from the scale of a representative elementary volume (REV), a volume for which the measured property does not change with an increase in scale over a given limit of scale. For retaining the original heterogeneous information, the decisive factor is the final grid adopted. Consequently, the REV Grid theorem has b...
