Batch corrosion inhibitors are extensively used to provide corrosion protection for oil and gas wells as well as the pipelines that transport the hydrocarbons to the processing facilities. The traditional method to estimate the volume of corrosion inhibitor is based on a Rule of Thumb calculation that utilizes a desired film thickness and the length and internal diameter of the pipe to be treated. A discussion of the field and laboratory tests that were conducted to evaluate the thickness of batch inhibitor films and some of the variables that may affect film thickness (e.g. dilution, pig type, production fluids) is presented in this paper.
