Paper: Simultaneous Mechanical Caliper Electromagnetic Caliper Log

The Pipe Inspection - Pipe Evaluation Logging System or P.I.P.E. Log is a valuable aid in determining casing deterioration due to wear and/or corrosion. The P.I.P.E. system combines a multi-finger mechanical caliper and an electromagnetic casing evaluation/caliper tool that are run simultaneously in the casing. Run in combination, the two systems complement each other in detecting single string casing corrosion.
