Routine pigging is one of the strategies used to manage wax-deposition risks in an oil pipeline. When routine pigging cannot be performed, the excessive amount of wax must be gradually removed by progressive pigging—launching a series of pigs with increasing diameters. We successfully optimized the progressive-pigging process in a subsea oil pipeline network by integrating wax-deposition modeling and pigging performance data into a pig-size calculation tool. The tool assists in selecting the diameter size of the first pig to launch while minimizing the duration of the remediation pigging program and preventing the production deferral.
