Corrosion is a pervasive issue that affects oil and gas production. It poses a significant threat to the safety and integrity of oil and gas equipment, and it can lead to costly repairs and downtime. Mitigating corrosion is a crucial part of maintaining the productivity and safety of oil and gas operations. The first paper in the Wellbore Tubulars Technology Focus feature, IPTC 21818, explores the prevalence of corrosion in the oil and gas industry and the strategies used to mitigate its effect, including use of alternative materials and their qualification.

The second paper in the feature, SPE 206340, deals with stuck-pipe incidents, a major cause of economic losses, safety hazards, and nonproductive time. With the use of artificial intelligence (AI) and machine learning (ML) techniques, however, these incidents can be prevented by analyzing drilling data. In recent research presented at the International Petroleum Technology Conference and other SPE conferences, various AI and ML models were developed to predict and prevent pipe-sticking symptoms. The authors of the paper used natural language processing applied to drilling memos to improve the accuracy and robustness of kick and lost-circulation detection.

Finally, paper OTC 31160 discusses the use of microelectromechanical systems technology to embed sensors in tubulars that measure temperature and pressure throughout a well’s life. With low power consumption and an adapted transmission technology, this technology can be used to access previously inaccessible well areas in real time.

Such technological strides in wellbore tubulars are revolutionizing the oil and gas industry by providing real-time data and making new areas of wells accessible. With the integration of intelligent pipe technology, nonmetallic casing strings, and powered wired drillpipe solutions, operators can better monitor their wells, adjust production parameters, and ensure the safety of their installations. These advancements are a significant step forward for the industry and are sure to have a positive effect on well integrity and safety for years to come.
