Abstract: A method of detecting defects in non-nested tubings or a casing includes acquiring a first set of data from an electromagnetic ("EM") tool run inside a first of the non-nested tubings. The method further includes calibrating the data to reduce effects from a second of the non-nested tubings, identifying a location of a defect in the first of the non-nested tubings or the casing, and adjusting the data to compensate for eccentricity if the defect is in the casing. The method further includes performing an inversion algorithm on the data, the inversion algorithm developed for a single tubing configuration.
