Relative permeability measurements are made on three core samples. The measured data are

summarized below:

Core sample 1

h = 1 ft

k = 100 mD

Soc= 0.35

Swc= 0.25

It is believed that a connate water saturation of 0.27 and critical oil saturation of 30% better

describe the formation. Generate Oil and water relative permeability data using new critical

saturation. Plot the averaging relative permeability data. Using data given, de-normalize the data to

generate the required relative permeability data.
