Inventory management for tubulars and oilfield equipment

摘要

A method of managing items of oilfield equipment comprising providing each item of equipment with a remotely readable identification tag, gathering data associated with the items of equipment, correlating the data with an identification code of the tag of each item in a signal bearing medium, storing the data cross-referenced to the code in a computer, interrogating the computer to locate items of equipment according to one or more criterion based upon the stored data, and identifying the location, preferably via triangulation using RFID detectors 414, 416, 418, of each item which satisfies the given criterion. A method of managing oil field tubular goods 402 comprising providing a tubular member having a remotely readable identification tag, gathering data associated with the tubular, which may be one of rotating hours, wall thickness and outer diameter, correlating the data and an identification code in a signal bearing medium, and invoicing for actual wear to the tubular as determined based on the correlating. The invoicing is preferably initiated automatically.
