A Comparison of Two-Phase Dynamic Upscaling Methods Based on Fluid Potentials

摘要: Although a number of methods for calculating dynamic pseudo-functions have been developed over the years, there is still lack understanding as to why certain method will succeed in some cases but fail others. In this paper, we describe results an assessment several upscaling methods, namely Kyte and Berry (KB) method, Stone Hewett Archer (HA) Transmissibility-Weighted (TW) method. We analyzed equations deriving investigated numerical simulations gas displacing oil, variety models enable us gain new insights into these, related, methods. particular, novel observations on based fluid potential are presented issue using predicted mobilities criterion accuracy clarified.
