Abstract
A microwave core monitor includes a sample cell which contains a test core of an earth formation. A microwave transmitter irradiates the test core with a beam of electromagnetic energy at a microwave frequency. A microwave receiver provides an indication representative of a characteristic of a liquid, or the absence of a liquid, in the test core in accordance with electromagnetic energy that has passed through the core. The sample cell further includes microwave absorber rods which prevent portions of the beam of electromagnetic energy not passing through the test core from reaching the receiver.
