The Impact of Reservoir Properties on Pseudo Functions: Upscaling of Relative Permeability

Relative permeability is the most challenging parameter during the scale-up process. Dynamic pseudoization approaches are the best methods for upscaling of relative permeability. However, dynamic pseudo functions are dependent to some reservoir properties. In this study, the effects of absolute permeability, PVT properties, vertical to horizontal permeability ratio, and reservoir dip angle on three dynamic pseudo functions of Kyte and Berry, Stone, and transmissibility weight were investigated. Different reservoir properties on a 2-D cross-sectional heterogeneous model were studied. Between the properties were studied, the ratio of vertical to horizontal permeability had the most pronounced impact on all dynamic pseudo functions. Dip angle also had an intensive effect on Stone pseudos.
