Magnetic Detection of Buried Oil and Gas Metallic Pipes

Magnetic detection of burried metallic pipes is a well-known application of this geophysical method, the “pipe” magnetic anomaly being easily recognised. Recent applications carried out in Romania aimed at locating abbandoned oil transportation pipes or gas transportation network in view of land “clearing” for new industrial or commercial facilities. The Ploiesti city area, hosting refineries and dense networks of oil trasportation pipes, enabled the authors to find processing methods for separating the “pipe” magnetic effects from other magnetic noises due to neighboring industrial facilities and electric lines. The Sibiu city area hosting buried gas transportation network at its limits offered good possibilities for a clear location of the pipelines, but also information on the subsequent modifications of the buried pipe network.
