The influences of calcium, magnesium, and zinc ions on the efficacies of inorganic and organic based halite precipitation inhibitors are compared and contrasted. Calcium ion enhances the activity of the inorganic inhibitor and decreases the efficiency of the organic inhibitor. Magnesium has negligible influence on the efficacy of either inhibitor. Zinc, although not commonly found in oilfield brines, has a significant inhibitory influence on its own, but this influence is largely canceled by the presence of the organic or, especially, the inorganic halite inhibitor.

Keywords: halite, inhibition, brine, oilfield, salt

This study describes a laboratory test system which was specifically developed to assess the ability of biocides to lower microbial corrosion rates. It was found that the common oilfield biocides THPS and glutaraldehyde, dosed at concentrations of 300 ppm for 4 hours weekly over 5 weeks, could reduce MIC rates from 109.7 mpy to as low as 4.3 mpy
