摘要
Methods and a system for detecting through casing formation resistivity. A method may comprise inserting an inspection device inside a tube, activating the transmitter coil, recording signals with the receiver coil array, creating a transmitter matrix from an electromagnetic field produced from the transmitter coil, creating a receiver matrix from the recorded signals, and determining a through casing formation resistivity of a target from the transmitter matrix and the receiver matrix. A method may further comprise determining a casing thickness of a target from the transmitter matrix and the receiver matrix. An inspection device may comprise a sensor array comprising a transmitter coil array and a receiver coil array. The inspection device may further comprise a sensor array housing, wherein the sensor array is disposed within the sensor array housing, a memory module, and a differential amplifier.
