Well Integrity Technologies (PRE17)


    This course covers the main aspects of Well Integrity, starting with the construction of the well. Keeping the well operation within the safety envelope is critical for any oil & gas operator (well integrity).
    Well integrity technologies are focusing on monitoring problematic wells, diagnosing the causes of those problems, and implementing techniques to mitigate and/or repair those problems in order to keep the wells operating safely and avoid release of hydrocarbons to environment.

    Course Level: Skill
    Instructor: Antonio Abreu

    Designed for you, if you are...

    • A petroleum or production engineer
    • A drilling or completion engineer
    • Oil field technical staff

    How we build your confidence

    • The course will be presented using properly designed slides, some with animation and several videos on relevant issues
    • Teaching methods include also calculations on related issues
    • Several examples of SAP (Sustainable Annulus Pressures) investigation will be presented

    The benefits from attending

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

    • The fundamentals of well integrity monitoring and all implications on production efficiency
    • How to monitor and identify well integrity problems and technical procedures available for their mitigation
