When pipeline is clean:
Original properties of pipeline are restored, back towards
parameters of Engineering & Design
Ri ht diti t d f i tiRight conditions are created for inspection

Mechanical Pigging
Removal of …. with mechanical pigsRemoval with pigs alone can be effective, however
risky and slow
Black powder & paraffin can stick and lodge pigs
Pigs pack solids into pits,causing errors in ILI
General 11
Oil & Gas Services
Mechanical Pigging
Good for removing free liquids
Breaks down particles to smallerBreaks down particles to smaller
particles
Smaller particles fill anomalies
Micro small particles cause downstreamMicro small particles cause downstream
nuisance problems
