High temperature sweet corrosion and inhibition in the oil and gas industry: Progress, challenges and future perspectives

摘要: Abstract Sweet corrosion is one of the most often encountered type steel materials in oil and gas production wells also a major cause serious corrosion–related material failure industry. The use inhibitors economical methods controlling sweet corrosion. Corrosion applied under bottom-hole temperatures up to 100 °C are usually stable generally show no technology-related problems their performance. Above this temperature, however, literature report relatively scarce. This poses challenge as drilling operations now drift deeper with higher temperature pressure. Consequently, scientific or patent review on for at high visible literature. Therefore, thorough high-temperature important. Herein, we research publications patents related reported least 90 °C. Nitrogen–based compounds widely used inhibitor chemistries. Research gaps still exists localized total dissolved solids (TDS) brine inhibitors. Future directions have been highlighted.
