Abstract
A borehole logging tool such as a wireline logging tool or a logging-while drilling tool includes a tool body; a transmitting antenna located in the body; a pulser for causing the transmitting antenna to transmit an electromagnetic signal; a receiving antenna, located in the body, which includes an array of receiver elements disposed around the longitudinal axis of the tool body; and electronics for measuring the difference in signals detected by pairs of elements in the array. The receiver elements can be linear dipole elements and the electronics for analyzing the signals measures the difference in signals measured by pairs of elements so as to determine the direction of a reflecting structure from the tool.
