Abstract

A method for estimating a thickness for each of a plurality of nested tubulars may utilize disposing an electromagnetic (EM) logging tool in a wellbore. The method may further utilize transmitting an electromagnetic field from the transmitter into one or more tubulars to energize the one or more tubulars with the electromagnetic field thereby producing an eddy, forming a measurement log from the plurality of measurements, and solving a first inverse problem with uniform priors to obtain a first set of estimated tubular parameters. The method may further utilize designing a data-driven prior based on the first set of estimated tubular parameters, solving a second inverse problem with the data-driven prior to obtain a second set of estimated tubular parameters, and using the second set of estimated tubular parameters to make informed decisions on the integrity of the well casings.
