Corrosion in the oil and gas sector is one of the major flow assurance issues. From an economic point of view, the efficient management of corrosion ensures that oil and gas can be recovered from wells for longer. Corrosion is also a major cause of hydrocarbon leaks and so safety drives the technological advances in corrosion control. There is currently an increasingly high demand for qualified corrosion engineers with specific expertise in oilfield operations. This course helps satisfy this demand by providing engineers and physical scientists with skills in corrosion measurement, asset integrity assessment, and corrosion prediction and corrosion management. This course covers the fundamentals, mechanisms and the main causes of the corrosion in the oil and gas production system. It also covers the corrosion control and monitoring method used in the oil and gas production system. The course contains practical examples of the oil and gas industry.

By the end of this course delegates will be able to:

• Identify the corrosion mechanism and estimate and predict the corrosion rate
• Select material for different corrosion environments
• Evaluate and select corrosion inhibitor for different corrosion environments
• Estimate the erosion rate
• Select corrosion monitoring techniques
• Elaborate a corrosion management plan for pipelines
