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

Paper ID: C2025-00073 ABSTRACT: In the petroleum and gas industry, managing corrosion is a critical and complex challenge, particularly in facilities with high sour gas, elevated water cut, and CO2 levels. These fluctuating parameters demand that corrosion control engineers remain vigilant and prepared to implement rapid and effective interventions.
This paper presents a case study on a 10" critical sour wet gas line, which has shown signs of corrosion over the past three years. This case exemplifies the dynamic decision-making required in corrosion management. This paper details evolving process conditions and proactive strategies employed to mitigate corrosion risks.
It highlights the journey of managing this line, focusing on the integration of various corrosion control barriers such as pigging, continuous corrosion inhibitor injection, and chemical batching. In-line Inspection (ILI) was also employed as part of the assessment to draw the corrosion management requirement for this line. Readers will gain insights into real-world corrosion control measures, understanding how continuous monitoring and adaptive strategies have been pivotal in maintaining the line's integrity and safety.
This paper underscores the importance of a responsive and dynamic approach in corrosion management.
