Question

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 Water

Saturation Sw 0.20 0.25 0.30 0.40 0.50 0.60 0.65 0.72 *Value at critical saturation Core sample 2 h = 1 ft k=80 mD 0.850* 0.754 0.557 0.352 0.131 0.000 Soc= 0.28 Swc = 0.30 Core sample 1 Kro Krw Core sample 2 Kro Krw 0.000 0.018 0.800 0.092 0.593 0.198 0.393 0.327 0.202 0.400* 0.111 0.000 0.000 0.077 0.191 0.323 0.394 0.500* Core sample 3 h = 1 ft k=150 mD Soc= 0.35 Swc = 0.20 Core sample 3 Krw 0.000 0.008 0.027 0.088 0.176 0.286 0.350* Kro 1.000* 0.872 0.839 0.663 0.463 0.215 0.000 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.
