Flow Assurance Technologies (PRE07)


    Flow Assurance is the ultimate foundation of an engineer's job: to assure and optimise the flow of oil and gas.
    This course covers the main aspects of flow assurance, from the reservoir to the production line, starting with the construction of the well (cementing technologies), then covering the main aspects of repairing formation damage (stimulation technologies) in order to maintain sustainable production and technologies to tackle problems related to well integrity (well integrity technologies).

    Course Level: Skill
    Instructor: Antonio Abreu

    Designed for you, if you are...

    • A petroleum or production engineer, a development geologist, reservoir modeller or field engineer keen to develop your knowledge on these areas
    • A production manager, field manager, drilling manager, etc.

    How we build your confidence

    • Instructor-led delivery focusing both on theoretical concepts and practical onsite experience
    • Videos and case studies

    The benefits from attending

    By the end of the course you will feel confident in your understanding of:

    • The fundamentals of cementing operations and all implications on production efficiency
    • How to select and design acid systems for Sandstone and Limestone formations in order to remove formation damage and restore and/or improve a well's productivity
