Abstract
A method of determining the oil and water relative permeabilities and the water saturation of a core of earthen material which includes providing a two phase oil/water liquid to and through said core. The core is irradiated with microwave energy while the liquid is in the core. A received energy signal is generated in accordance with the microwave energy that has passed through the core. A liquid pressure drop along a predetermined length of said core is sensed and a representative pressure drop signal is provided. The oil and water relative permeabilities and the water saturation of the core are derived in accordance with the flow rate of the liquid, the received energy signal and the pressure drop signal. The liquid flow rate may be either sensed or the liquid may be provided at a predetermined flow rate.
