Abstract: Methods, systems, and computer program products for inspecting a pipe in a well using an eddy-current based pipe inspection tool comprises conveying the pipe inspection tool through the well, obtaining a first voltage measurement at an axial position along the pipe from at least one main receiver. The first voltage measurement includes a residual voltage induced in the at least one main receiver by a residual magnetic field resulting from residual magnetism in the pipe. A second voltage measurement is obtained at said axial position along the pipe from at least one second receiver. The first voltage measurement and the second voltage measurement are processed to obtain a processed measurement representing a difference between the first and second voltage measurements. The processed measurement is substantially free of the residual voltage and may be use to estimate a thickness of the pipe and other pipe characteristics.
