Abstract The utility of oxygen scavengers for the control of corrosion in production environments is demonstrated through a combination of laboratory studies and field trials. Even in the absence of conventional corrosion inhibitors (e.g., film-forming species), dramatic reductions in corrosion rates were observed in wells exhibiting dissolved oxygen concentrations persistently above industry-recommended thresholds. Systematic laboratory screening studies were used to assess a variety of oxygen scavenging molecules and formulations. Mechanistic (pH, temperature, catalysis, etc.) as well as economic considerations led to the development of a product that is well-suited to oilfield environments. Two separate field trials, spanning more than 20 wells using gas lift systems in the Delaware basin, were conducted over a period of 6 months. The scavenger was injected either concurrently with methanol used to prevent hydrate deposition, or independently into the gas stream. Product performance was assessed by monitoring dissolved oxygen and dissolved iron concentration in the flowback stream. Prior to the introduction of the scavenger, dissolved oxygen concentrations were consistently well above industry-recommended thresholds (20-50 ppb), averaging more than 85 ppb across the initial 11-well trial. Concentrations were even higher in the second 10-well trial, averaging over 150 ppb. Likewise, iron production rates were high, averaging over 70 lbs/day per well, resulting in the need for frequent and costly casing replacements and extensive treatment of the produced water. Average tubing life was only 9 months in the absence of a treatment program. Additionally, frequent failure of surface valves and fittings due to corrosion resulted in environmentally impactful spills. Downtime and costs associated with repairs and cleanup were significant. Numerous corrosion inhibitor packages had been applied to try and mitigate this behavior; none proved successful. Upon starting the scavenger treatment, dissolved oxygen concentrations in the produced fluids dropped rapidly. In as little as 7 days at a treatment rate of 10 gpd, nearly 80% of the dissolved oxygen was removed. Further reductions continued in the following weeks. Critically, there was also a substantial reduction in dissolved iron content, which strongly suggests a reduction in the casing corrosion rate. Iron production rates dropped to below 15 lbs/day within 3 months. Oxygen-driven corrosion has been discussed previously in the literature, but it is often not recognized as a major contributor to oilfield corrosion. The results of this study show that the patent pending scavenger formulation described herein is a very effective tool for corrosion management, especially when conventional corrosion inhibitor treatment strategies prove ineffective.
