In the global oil and gas exploration industries, the yearly losses resulting from corrosion and the associated rectification expenses amount to several billions of dollars. The need for new materials with unique failure behaviors arises from high production under harsh and extreme operating conditions. As a result, industry operators are constantly reviewing various corrosion management techniques. However, unanticipated corrosion-related failures of top-side, subsurface, and subsea infrastructure result in both production loss and fatalities. For production wells and other facilities to operate safely and profitably, corrosion management techniques include corrosion preventive measures, prediction of failure behaviors, and remaining useful life.

Course Objectives:

This course is designed for engineers and operators engaged in oil and gas exploration industry requiring an understanding of corrosion fundamentals: the causes and control of corrosion in oil and gas production and processing. This course will provide an overview of what corrosion is and what the major corrosion issues are in upstream oil and gas operations. The focus will be on understanding how materials corrode, what techniques are used to monitor corrosion and some basic corrosion control fundamentals. The participants will be introduced to inhibitors and how they work, corrosion monitoring in field applications and cathodic protection. The course content is presented from a practical production operations viewpoint and provides participants with the basic skills and understanding to control and solve corrosion issues.

Who Should Attend?

Personnel who are working in technical areas related to assets integrity management who deal directly or indirectly with corrosion monitoring and its control.
