One type of intensification of natural gas recovery is the treatment of wells with mineral acids or combinations, which contain acid, so-called acidizing. Compositions for acidizing except acids also include foaming agents. Inhibitor-foamer INCO-K is designed to protect process equipment from corrosion occurring due to the action of acids, as well as to create foam in highly acidic media. Thus, the use of INCO-K does not require additional introduction of foaming agent into composition for acidizing, which simplifies the technology of acidizing and reduces the cost of its implementation.

NCO-K inhibitor may also be applied where necessary protection of metals from acid corrosion.
