Optimizing Corrosion Inhibitor Batch Treatment Intervals For Oilwells

This paper chronicles efforts to extend batch treatments using hydrocarbon-solvent solutions of corrosion inhibitor. Inhibitors were developed in the laboratory using parameters felt to be important for this endeavor. That is, good high inhibitor concentration inhibition, good reduced-inhibitor inhibition, and intermediate brine dispersibility. Field- testing proved these inhibitors to be effective during the extended intervals.
