Flow Assurance Technologies (PRE07)


    This course covers the main aspects of Flow Assurance, 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.
    Keeping the well operation within the safety envelope is also critical for any oil & gas operator (well integrity technologies).

    The course starts by presenting the basic concepts for Cementing Job Design, execution and follow up, stressing the importance of efficient cementing operations and their impact on the well life cycle.
    Emphasis is also placed on removing formation damage in order to restore or improve the well's productivity (stimulation technologies).

    Well integrity technologies, focusing on monitoring problematic wells, diagnose the causes of those problems, and implement techniques to mitigate and/or repair those problems in order to keep the well operating safely, therefore decreasing the expensive list of inactive wells (very costly on lost production).

    Course Level: Intermediate
    Instructor: Antonio Abreu

    Designed for you, if you are...

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

    How we build your confidence

    The course focuses both on theoretical concepts and practical onsite experience.
    By the end of this course you will feel confident of understanding the importance of the issues presented and discussed, in order to optimise the performance of the most important assets of your company, besides their people: the producing wells.
