Fundamentals of Underbalanced Drilling (DRI06)

    Description

    This course is designed to provide an excellent overview of underbalanced drilling principles. It will address design basics, calculations and "field tested" rules of thumb fundamental to achieving the successful execution of an underbalanced drilling project.

    Course Level: Foundation
    Instructor: Frank Seidel

    Designed for you, if you are...

    • An engineer, a technologist, wellsite supervisor, service personnel or someone involved in the design, planning and execution of underbalanced drilling (UBD) projects

    The benefits from attending

    • The course provides a basic understanding of underbalanced drilling by defining the process requirements, explaining specialised equipment and underbalanced drilling fluid systems.
    • The advantages and disadvantages of underbalanced drilling, design considerations and where and when to apply UBD successfully will be discussed.
    • The course teaches basic calculations and uses real life case histories to demonstrate their use.
    • Design basics utilising commercial UBD design programs will be demonstrated.
    • The course provides a comprehensive overview of UBD regulations and risk management and will cover emerging UBD technologies.
