51317--9564-Inhibited Under-Deposit CO2 Corrosion: Small Particle Silica Sand and Eicosane Paraffin Deposits

This paper suggests a new mechanism for explaining physics behind the localized corrosion attack based on experimental evidences. The effect of sand size and deposit type on localized corrosion attack in the presence of imidazoline type inhibitor is also experimentally investigated.

Chemical inhibition in the presence of silica sand deposit has been reported as a cause of severe localized corrosion attack in CO2-saturated brine environments. This paper suggests a new mechanism for explaining physics behind the localized corrosion attack based on experimental evidences. The effect of sand size and deposit type on localized corrosion attack in the presence of imidazoline type inhibitor is also experimentally investigated in CO2 saturated brine solution. Smaller silica sand particles are found to cause less localized attack in compare with larger sand particles. Localized corrosion attack in the presence of paraffin deposit is also negligible compared to silica sand deposit.

Key words: under-deposit, localized corrosion, inhibitor, sand, paraffin
