One method to control significant metal losses occurring due to corrosion in the oil and gas industry is to use corrosion inhibitors. Erosion-corrosion occurs when corrosion is accompanied by solid particle impingement. Erosion-corrosion is receiving increased attention due to the current trends in operating with sand especially in systems where flow with sand creates conditions of greater well inflow production rates than is normal for the reservoir pressure condition.1 The goal of this research is to determine the ability of an inhibitor to effectively control erosion-corrosion in an environment similar to that of wells producing CO2 and sand. A submerged direct impingement jet system with a velocity of 13 m/s was employed to examine inhibitor performance with a sand and CO2 environment for a range of sand concentrations. For all concentrations of sand tested, adding an inhibitor reduced erosion-corrosion metal loss rates compared to not using an inhibitor.
