Corrosion control in the presence of trace amount of O2 has been a continuous challenge in the oil and gas industry. The objective of this work is to develop and evaluate a new oxygen tolerant corrosion inhibitor (CI) under various conditions for both continuous and batch treatment in the field. Corrosion evaluation tests were conducted in kettle, RCE, and autoclave, with various CO2, H2S, and O2 conditions. Continuous injection and film persistency methods were carried out to assess if the inhibitor can be applied in continuous injection and batch treatment. A comparison study was also performed between this new inhibitor and an incumbent product. The Results show the new inhibitor performs well in all the tested conditions. It shows good partitioning behavior into the water phase in kettle tests and better corrosion inhibition and film persistency than the existing widely applied incumbent in RCE tests. Autoclave tests indicates the product performed well at 275oF and 21 bar CO2 pressure. Specifically, it still provides good protection against up to 3 ppm O2 in the aqueous phase, implying strong oxygen tolerance. This new developed corrosion inhibitor improves oxygen tolerance and can be applied in both continuous and batch treatment.
