Craig Mobility Ratio Calculation

Calculate the Craig mobility ratio from the relative permeability and viscosity information provided.

Note that the average saturation behind the front for this rock$-$fluid system was determined to be $0\mathrm{.}72.$

Oil viscosity, $O=2\mathrm{.}0cp$

Water viscosity, $w=1\mathrm{.}0cp$

Initial water saturation, Swi $=0\mathrm{.}2$
