Description

The demand for improved quality of borehole measurements requires improvement of instrument designs and of data interpretation. One important requirement in cased hole surveys is to provide more accurate, and more localized inspection of the pipe’s wall [1]. In order to accomplish this, sensor coils should be located as close to the pipe wall as possible. That, in essence, requires the use of an array of sensor coils covering the entire circumference of pipe, which may have an arbitrary position inside of pipe and, as a result, different axises with regard to the exciting coil (Fig. 1).

Theoretical and Experimental Investigation of Eddy Current Inspection of Pipes with Arbitrary Position of Sensor Coils
