terms:electronic_casing_caliper_logging
A technique which uses an electromagnetic noncontact method of relating currents induced on the inner surface of casing or tubing to the inner diameter of that casing or tubing. A coil system generates an electromagnetic field which induces currents on the inner surface of pipe. These currents are detected by a second coil system. The measurement obtained is related to the average inner diameter of the pipe over a length of one or two inches. The technique can be used to record the inner diameter of pipe through scale, paraffin. or cement adhering to the inner surface, and to detect some vertical splits and holes.
