Evaluation of oil field chemicals for secondary oil recovery systems in Kuwait

Abstract

Experiments were conducted with carbon steel to investigate the corrosion protection performance of five commercial chemicals as inhibitors in oil field effluent and aquifer waters. The effect of different inhibitor concentrations and flow velocity was determined using the disc electrode (RDE) method. The corrosion rate of carbon steel under stagnant and flow conditions was determined by the linear polarization resistance (LPR) method at a scan rate of 0.1mV/s versus a saturated calomel electrode (SCE). All experiments were conducted at 82^○C. Results indicated that a blend of ethoxylated amine inhibitor for the effluent water, alkylpyridinium‐oxyalkylated‐alkylphenol amine salts inhibitor was found to be the best for both the effluent and aquifer waters.
