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 technologies).
    Well integrity technologies, 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.

    Course Level: Advanced
    Duration: 5 days
    Instructor: Antonio Abreu, Luis Remisio, Cipriano Costa

    Designed for you, if you are...

    • Petroleum engineer
    • Production engineer
