Keywords:
Electrochemical Corrosion Monitoring, Pipeline Integrity, Potentiodynamic Polarization, Electrochemical Impedance Spectroscopy, Corrosion Management in Oil IndustryAbstract
Corrosion in oil pipelines is a critical challenge that threatens the safety, sustainability, and economic viability of the global petroleum industry. With pipelines exposed to harsh environmental conditions, managing corrosion has become essential to prevent operational failures and costly disasters. Electrochemical methods have emerged as cutting-edge solutions, offering real-time precision in monitoring the degradation of pipeline materials. Techniques such as potentiodynamic polarization, electrochemical impedance spectroscopy (EIS), and linear polarization resistance (LPR) provide valuable insights into corrosion rates and the performance of protective systems. This review examines these methods while exploring how innovations in artificial intelligence (AI) and nanotechnology are enhancing their capabilities. AI-driven analytics enable predictive maintenance by processing vast sensor data, while nanomaterial-based sensors offer higher sensitivity, detecting corrosion earlier than ever before. By integrating these advances, the oil industry is shifting from reactive to proactive corrosion management, ultimately extending the lifespan of pipeline infrastructure and reducing risks. This paper synthesizes the latest research to provide a roadmap for the adoption of advanced electrochemical monitoring systems, essential for the long-term safety and reliability of oil pipelines.
