Adaptive workflows for artifact identification in electromagnetic pipe inspection

A method for identifying an artifact disposed in a wellbore comprising:

• disposing an electromagnetic logging tool into a first wellbore;
• broadcasting an electromagnetic field from a transmitter disposed on the electromagnetic logging tool;
• energizing a casing with the electromagnetic field;
• recording a secondary electromagnetic field from the casing at a plurality of depths and at a plurality of frequencies;
• picking a first plurality of artifacts in the first signal;
• constructing a target value matrix from the first plurality of artifacts;
• producing a first input matrix from the first signal and a first well plan;
• constructing a predictor from the first input matrix and the target value matrix;
• disposing the electromagnetic logging tool into a second wellbore;
• broadcasting a signal from a second transmitter disposed on a second electromagnetic logging tool;
• recording a second signal;
• producing a second input matrix from the second signal;
• producing a second plurality of artifacts from the predictor and the second input matrix;
• and
• displaying the second plurality of artifacts to an operator.
