abstract="New buried identification marker technology offers potential improvements in oil and gas pipeline-maintenance efficiency and reduction of the likelihood of accidental damage and associated safety hazards. Electronic marking, locating and identifying of systems used by telephone companies, power companies, water and sewer utilities and cable companies can also protect underground gas and oil pipelines in urban and rural settings by marking road crossings and important buried features. A new buried identification marker system incorporates preprogrammed marker identification, making it possible to locate and identify quickly the depth and exact properties of the marked object without excavation.
