Corrosion is the most important and costly cause of severe operational problems encountered in oil and gas production systems. It may occur anywhere in the production system, from the oil/gas well bottom to the final transfer of produced gas or oil to the refinery. Internal corrosion of carbon steel pipelines is a common and serious problem in oil and gas production, which is designed for long-term operation. It involves an interaction between the metal wall and the flowing fluids. This problem has caused the consideration of many corrosion control programs and research in various oilfields around the world. There is global use of carbon steels as materials of construction for pipes in the oil and gas industries.  Compounds triazoles and their derivatives have attracted huge attention due to their simple preparation and superior corrosion inhibition activity towards mild steel in acidic environments. Therefore, the present review aims to highlight the carried out using Compounds triazoles and their derivatives for steel protection in different corrosive environments.
