The problem is solved analytically even for the unequal viscosity case. This is the first attempt known to these authors not only of using this analytical method...

.... Gotawala and Gates (2008b) examined stability of the edge of a steam chamber by using reservoir simulation. In this study, three simulation models with different relative permeability sets have been studied. The set of relative permeability is given in Table 3 as Cases A, B, and C (following from Butler...

It still remains unclear how multiple phases flow in fractures and how to determine the relative permeability of each phase that can be used in reservoir simulators. In typical practice, simulation...
