ACOUSTIC MEASUREMENTS DETECT SAND IN NORTH SEA FLOW LINES
Trond Folkestad, Kanaga S. Mylvaganam Chr. Michelsen Institute Bergen, Norway Clamp-on acoustic emission (AE) transducers have been developed for detecting sand in flow lines on offshore oil producing platforms. Sand production is determined by using the integrated value of measured noise generated by collisions of sand particles on the pipe wall. During the field's life, sand production can do excessive damage and result in expensive repairs that might occur at any time and in any well.
