摘要：
Apparatus and methods to image pipes of a multi-pipe structure can be implemented in a variety of applications. The multi-pipe structure may be associated with a well site, such as a multi-casing structure for a production well. Individual pipes of the multi-pipe structure may be investigated in a multi-stage process using delta-like responses, where previous stages provide inputs to subsequent stages. The results of multi-stage processing can be used to image defects in the multi-pipe structure.
