... include heterogeneity at multiple scales within a reservoir ( Ringrose et al., 2008 ). Indeed, from a geological perspective it is recognized that heterogeneity exists at all scales from the pore to geological features over several kilometers. Four levels of heterogeneity that impact fluid flow have been...

We demonstrate that the validity of this assumption depends on the length of the history match period and that of the forecasting period. It also depends on how heterogeneous the reservoir is. The correlation between the quality...

There are a wide range of principles one can use to accurately account for the remaining heterogeneity that is not represented in the geologic parameters used for the first hierarchical coarsening...

To overcome this limitation, an effective-fingering model was developed...
