Classification: CPC E  G | IPC E  G

Claim 0:
1. A method comprising:
forming a measured log including a set of log measurements at different depths using an electromagnetic pulsed tool disposed in multiple nested conductive pipes in a wellbore;
generating one or more remote-field eddy current (RFEC) look-up curves based on measurements of normalized signal level responses for the multiple nested conductive pipes at one or more points in a time decay response;
selecting an RFEC look-up curve at a point in the time decay response that indicates a total thickness of the multiple nested conductive pipes irrespective of a thickness for any specific one of the multiple nested conductive pipes; and
determining the total thickness of the multiple nested conductive pipes at each depth in the measured log using the selected RFEC look-up curve.
