ABSTRACT:
A method of testing a chemical for use in an enhanced recovery of oil from an earth formation includes obtaining a test core of an earth formation. The test core is cleaned and then subjected to a predetermined sequence of events similar to that which the reservoir has experienced. The test core is flooded with a chemical to be tested and the chemical is then driven from the test core with a drive liquid. The test core is irradiated with a beam of electromagnetic energy at a microwave frequency. An indication representative of the effectiveness of the chemical in the test core is derived in accordance with the electromagnetic energy that has passed through the test core.
