Sažetak
In order to ensure the safety of the environment during hydrocarbon extraction operations, downhole nondestructive testing of the well casings is of the utmost importance. To this purpose, rotating field eddy current has been recently proposed as an alternative to the state-of-the-art array sensors and mechanically rotating sensors. In this paper, we present an analytical approach to modeling of such a sensor. We study the sensor sensitivity to the small defects by coupling the model with the dipole-based model of small defects.
