Introduction
Destructive reactions between metals and acids cause serious corrosion problems in acidizing operations. Corrosion inhibitors are generally required in acids to minimize these destructive reactions without introducing adverse effect on reactions between acids and formations. Corrosion inhibitors is an amine formaldehyde resin used in hydrochloride and mud acid systems to prevent tubular or equipment from serious acid corrosion.

Chemical Properties and Application
Corrosion inhibitors is an amine formaldehyde polymer which can be used for most acid systems for most applicable tubular materials.
Corrosion inhibitors is dispersible in acids. The barriers established by Corrosion inhibitors on tubular surface avoid contact areas between acids and metal surface and therefore corrosion chemical reactions are stopped. Corrosion inhibitors is effective for most metals including carbon steels and chrome steels. It can also be used in most acids such as hydrochloride and hydrofluoride. Minimal corrosion and pitting problem are observed on tubular and equipment using acids containing Corrosion inhibitors.
Corrosion inhibitors is compatible with most additives and acid systems. Lab testing is required when surfactant other than Corrosion inhibitors or acids other than HCl and HF are used. Special attention is required for Corrosion inhibitors design for sour gas (H2S and CO2) wells.
