Fluid Corrosivity Factors in Well Production

Vertical well gas /liquid flow pattern

Solids from well production

Corrosivity of oil/gas/condensate wells

1) Chemistry of production fluid

• Water cut
• Acidic components CO2, H2S, etc
• Minor species with corrosion implications (Hg, etc)
• Species with scaling implications ( alkalinity, hardness, silicate, etc)
  

  Downhole scale prevents corrosion

2) Process parameters

• Temperature,
• Pressure,
• Velocity ,
• Pressure drop
• Flow dynamic pattern

3) Cyclic loading, stress and wear

4) Erosion, abrasion and cavitation
