Surface Production Operations (PRO06)

    Description

    This course will cover the basic concepts and techniques necessary to design, specify and manage oil and gas field surface production facilities. It provides a clear understanding of the equipment and processes used in common separation processes, gas condensate treatment as well as oil and water handling. The basic fluid descriptions will cover chemical and process related subjects and will support a better understanding of the complex treatment processes. Modern methods of computerised surveillance programs will be presented and guidelines for many issues will improve participants' daily operating skills.

    Course Level: Intermediate
    Instructor: Wolfram Kleinitz

    Designed for you, if you are...

    • A production or facility engineer, project manager, production chemist, a member of field operational staff currently or potentially involved in natural gas or oil production operations
    • A professional seeking a modern overview of sustainable improvements in the gas / oil production process

    How we build your confidence

    The course focuses on practical onsite experience. Case histories and practical examples will be subdivided into the following sections: System description, theoretical background, modern monitoring and control systems, weaknesses in treatment units as well as the aspects of “over-engineering”. To improve the understanding of special treatment processes videotapes will be shown and discussed.

    The benefits from attending
