Corrosion management in Oil and Gas processing facilities has always been a challenge mainly for facilities processing fluids with high water cut. One early production facility (EPF) experienced severe corrosion in its produced water circuit owing to change in composition of well fluids. Design basis along with H&MB modeling anticipated 0.45% CO2, <10 ppb dissolved oxygen and <10 CFU/ml microbial count however, in actual facility experienced >3% concentration of CO2, up to 22 ppb of dissolved oxygen and >160K CFU/ml microbial contamination through well fluids and wash water. These conditions altogether created extremely corrosive environment which resulted in 49 leakages in produced water circuit over the period of 05 year’s operation. Most of these leakages could have been averted if proactive corrosion management approach would have been taken during the initial stages of facility operation. This paper emphasizes on the importance of maintaining an evergreen corrosion management strategy to reduce leakages and asset maintenance cost.
