Corrosion Engineering Awareness in Oil & Gas Operations (PRO14)

    Description

    This course describes the corrosion process in gas/oil/water production systems, its control philosophy, practices and innovative approaches applied to combat corrosion problems. The course also makes clear how the dominating factors of corrosion in treatment systems can be identified and how to mitigate their impact by material selection, inhibitor application or coating of critical sections. The impact of bacteria, oxygen ingress to the system as well as predictive methods for corrosion will be discussed based on practical experience.

    Course Level: Advanced
    Instructor: Wolfram Kleinitz

    Designed for you, if you are...

    • An engineer, project manager, chemist or field operational staff currently or potentially involved in corrosion processes
    • A corrosion engineer involved in the daily gas/oil/water treatment process
    • A professional seeking an overview of sustainable application for corrosion management

    How we build your confidence

    You will work on practical problems to ensure a better awareness of corrosion-related issues like impact of water/gas/oil composition on material attack. You will elucidate the main drivers in the corrosion process under operating flow conditions and you will get tools for material selection, inhibitor screening methods, monitoring systems etc. in face-to-face discussions. All the presented field examples are based on practical experience.
