Example $1$

Endpoint Mobility Ratio Calculation

Calculate the endpoint mobility ratio from the relative permeability and viscosity data given below.

$$ Oil viscosity, $O=4\mathrm{.}0cp$

$$ Water viscosity, $w=2\mathrm{.}0cp$

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

Example $1$ Solution Endpoint Mobility Ratio Calculation

The endpoint mobility ratio equation is:

$M=\frac{(\frac{k_{rw}}{{}_w}{)}_{S_{or}}}{(\frac{k_{ro}}{{}_o}{)}_{S_{wi}}}=0\mathrm{.}75$
