Abstract
A method of identifying a bed boundary in a subterranean formation by processing data measured by an induction logging tool. An interferometric method compares recorded voltages and/or phases recorded at axially spaced apart receivers on the logging tool. A transmitter is on the logging tool and set between the receivers, where the receivers are equally spaced apart from the transmitter. The transmitter emits a signal having frequencies up to around 50 kHz.
