France, Germany: Monitoring field pipewall deposition with a new non-intrusive device ///

A new device for the detection of deposits that build up at the wall of pipelines and flowlines during production underwent recent industrial development by Cybernétix and IFP, in partnership with Total. It was further tested in early 2005 for 100 days on an onshore production line operated by Geopetrol, in southwest France. The line produces Montastruc field. Well MTC4 has a diameter of 2 in., is about 500 m long and is buried at a depth of 1.80 m after the wellhead. It produces 12 m3 (75 bbl) per day of water-free oil. It is periodically pigged using a foamy pig. Two devices were installed on the pipeline, near the wellhead, for demonstration. One was placed downstream of the pig entry station and the chemical-injection point.
