Dynamic Decision-Making in Corrosion Management: a Case Study of 10" Sour Wet Gas Line

Abstract In the petroleum and gas industry, managing corrosion is a critical and complex challenge, particularly in facilities with CO2 content, high H2S concentrations and elevated water cut. These fluctuating parameters demand that corrosion control engineers remain vigilant and prepared to implement rapid and effective interventions. This paper examines the lifecycle of a 10-inch critical sour wet gas pipeline from commissioning in 2018 to 2024. The case studies illustrate the dynamic decision-making required for corrosion management and highlight the evolution of operational strategies, including pigging frequency optimization, transitioning corrosion inhibitors, and implementing monitoring systems. These decisions were influenced by continuous monitoring, in-line inspections, and process simulations. The findings underscore the importance of adapting corrosion control strategies to changing operational conditions to maintain pipeline integrity and ensure safe, efficient operation.
