Detection of paraffin deposition inside a draining tubulation by the Compton Scattering Technique

This work shows an application of the Compton Scattering Technique (CS) in the detection of the problem produced by the formation of paraffin (condensed petrol) inside the petrol draining pipeline in deep-water exploration (off-shore). This study was made using an inspection system by CS. The measurements were made with two types of beam, punctual and fan-beam, by analysing a pipeline cross-section or small elements of volume through a transversal line. The punctual system can detect a minimum of 10% paraffin. This value is about 20% with a fan-beam system.
