Film forming corrosion inhibitors are often selected to control CO2 corrosion and their effectiveness versus microbiologically influenced corrosion (MIC) is desirable in systems that suffer from both forms of corrosion. Traditional corrosion inhibitor tests (e.g., bubble tests) have unfavorable conditions for microbial activity and are inadequate for evaluating MIC control. Biocide screening test methods have been used to evaluate microbial kill with toxic chemicals added batch wise, providing very little direct information about controlling corrosion. Once-through flow cells containing corrosion coupons were inoculated with a field consortium enriched in synthetic produced water to simulate MIC field activity. Maximum pitting rate on the coupons was the key performance indicator for screening inhibitors. Results indicated that many of the corrosion inhibitors tested increased the maximum MIC pitting rates when compared to untreated controls. In at least one case, a less toxic inhibitor provided better MIC control than a more toxic inhibitor. Data suggest that the field microbial consortia used in the testing developed a resistance to an incumbent inhibitor that has been used for many years. The results indicate that inhibitor selection based on MIC control is not simply a function of their ability to control bacterial growth and activity. Key Words: Microbiologically Influenced Corrosion, corrosion inhibitors, produced water, sulfate reducing bacteria

Assessing the Corrosivity of Field Produced Water in in-situ Oil Sands Water Treatment Systems

Product Number: 51317--9389-SG
ISBN: 9389 2017 CP
Author: Tesfaalem Gebremedhin Haile
Publication Date: 2017
$20.00

A study on the corrosivity of field produced water obtained from in-situ oil sands operators to UNS G10180 carbon steel. Rotating cylinder electrode (RCE) and rotating cage autoclave (RCA) systems were used as test methods. The susceptibility of the carbon steel to pitting was also evaluated.
