Oil and gas production operations use intelligent pigs for corrosion inspection of gathering systems and pipelines worldwide. The authors have been involved with intelligent pig inspections which have been conducted on over 155 different pipelines owned by one international corporation. A variety of intelligent pig vendors have been used with tools ranging from standard first generation magnetic flux leakage (MFL) to high-resolution MFL to standard and custom made ultrasonic (UT) tools. Experiences encountered during these inspections are discussed and resolutions to many of the problems are described.
