Honarpour Gas-Oil Relative Permeability

Generate gas-oil relative permeability curves using Honarpour et al. (1982) empirical correlations. Separate equations for sandstone (Eq A-4, A-5) and carbonate (Eq A-9, A-10) rock types.

Parameters:

• Swi: Irreducible water saturation
• Sorg: Residual oil saturation to gas
• Sgc: Critical gas saturation
• krgAtSorg: Gas relative permeability endpoint at residual oil saturation
