Blockage Detection

The accumulation of wax and debris is a main cause of the blockage in pipelines.

Because the actual severity of the wax or debris accumulation cannot be known with absolute certainly a common issue with progressive pigging is that even the first foam pig can get stuck. This often results in a recovery pig being sent in to retrieve this stuck pig but then the recovery pig also gets stuck doubling the problem. Additionally subsequent pigs can get stuck because they remove too much wax which builds up in front of the pig causing it to stick further down the pipeline.

SANCCUS SOLUTIONS

By pumping a specific oil based crosslinked pipeline gel before any pigging starts and closely monitoring the pressure response the exact location (depending on the accuracy of the flowmeters) can be determined since you know how much fluid you have pumped and the geometry of the pipeline so when you see a pressure spike the client knows how far down the line the blockage is located and to some degree its severity.
