Case Study: Hearing the Pig Coming: Leapfrog Tracking of an MFL Run in West Texas
A third-party pig tracking company tracked a 2-mile MFL inline inspection run in West Texas using just two Propipe North America APEX Above Ground Markers (AGMs) fitted with geophones. The tool carried no transmitter, so the APEX units detected its strong magnetic signature while the geophones picked up its sound. The crew leapfrogged the two units ahead of the pig, streamed data live over cellular, and detected every passage.
