OBJECTIVES:
This application can be used to calculate average gas-oil relative permeability curapplication can also be used to re-normalize an existing relative permeability curvSgc, Krg@Sorg, Krog@Sg=0 and preserve the same general curve shape.
MAJORASSUMPTIONS- Krog is normalized between Sg = 0 and Sg = (1 - Sorg - Swir)- Krg is normalized the same way as Krog for the individual relative permeability- The final average Krg curve is re-normalized between Sg = Sgc_avg and Sg = (1- Individual rock curves are linearly interpolated from the de-normalized curves atwith the average rock curve.- User defined weighting factors are also normalized between 0 and 1 prior to mul
