When batch treatment is used to provide corrosion protection in a gas well, a limited quantity of inhibitor is injected into the tubing string over a period of a few hours. The inhibitor may be used as received from the manufacturer or alternatively, a solution or dispersion of the inhibitor may be prepared by dilution with water or a hydrocarbon, such as diesel oil or lease condensate. After injection is completed, the well is left shut-in to allow the inhibitor to drain into the lower portion of the well. As the liquid flows down the tubing string, a film of inhibitor is deposited on the metal surface. This film is formed because the active component in the corrosion inhibitor solution has a greater affinity for the metal surface than for the solvent. The film of corrosion inhibitor prevents or reduces the dissolution of the metal by the various gases and liquids which emanate from the well. Results are presented and conclusions are drawn from experiments using radioactive corrosion inhibitors in batch treatment of gas wells. Two types of inhibitors were used in the experiments, the normal and the high density or heavy inhibitor. A normal inhibitor is one which has a density of about 7.5 lb per gal.
