Abstract
The present invention is a thin bed resistivity well logging system and method which includes a transmitter transmitting electromagnetic energy into an earth formation, from within a borehole traversing the earth's formation, at a frequency lying within a range of frequencies from 500 kilohertz to 4 megahertz. The system, a portion of which is located in the borehole, determines the true resistivity of a thin strata in accordance with the transmitted electromagnetic energy that has propagated through the earth's formation.
