Pipeline operators regularly run pigs for various applications, such as cleaning, batching, and integrity inspections. These runs are often completed without the aid of transmitters or pig tracking, making it difficult and problematic to pinpoint the location of a pig if it happens to get stuck in the pipeline.

This paper will discuss recent research and advancements in locating stuck pigs using a non-intrusive technique with a technology known as large standoff magnetometry (LSM). Additionally, the influence that operational and pipeline conditions, operating factors, and technical calculations have on the process will be deliberated; likewise, the collection and analysis method, and future developments will be presented. Finally, a case study from a recent project will present the cost-effectiveness, process efficiency, operating procedures, and reduced environmental impact of the LSM technique when compared to standard methods of identifying the location of a stuck pig.
