The phenomenon of corrosion is a serious problem in the natural gas production industry and is the result of chemical or electrochemical reactions of metal elements with the environment. In order to prevent corrosion in gas wells, corrosion inhibitors reducing the corrosive action of produced natural gas on steel parts of equipment and pipelines are used. Liquid corrosion inhibitors of varying chemical nature are used as corrosion inhibitors: most frequently quaternary ammonium salts, imidazoline derivatives, fatty acid salts, and protective gaseous inhibitors, usually volatile amines. In our studies, new corrosion inhibitors used to protect surface and subsurface installations were developed. These corrosion inhibitors are based on alkylsuccinic acid derivatives and are adapted to the operation gas from Polish shale formations. Additionally, research was focused on obtaining high performance and environmentally friendly corrosion inhibitors. In order to assess the effectiveness of corrosion inhibitors, static and dynamic corrosion tests as well as corrosion tests under elevated pressure conditions were performed. All functional tests: static method involving the immersion of metal plates in corrosive medium (e.g. brine) at the selected temperature (60°C), dynamic test; so-called "Wheel Test" and pressure method using the CoreLab RDA-100 apparatus, have shown, that the effectiveness of the corrosion inhibitors obtained is very high. Developed corrosion inhibitors can be used successfully in gas wells, and they can successfully compete with commercial corrosion inhibitors available on the market.
