Corey Relative Permeability Curves

Generate oil-water relative permeability curves using the Corey power-law model. This simple model requires only endpoint values and exponents, making it ideal for screening studies.

Parameters:

• Swi: Irreducible water saturation (immobile water)
• Sorw: Residual oil saturation (oil left after waterflood)
• No, Nw: Curvature exponents (higher = more concave)
