Directional, Horizontal and Multilateral Drilling (DRI08)


    This course builds a firm foundation in the principles and practices of directional drilling, calculations and planning for directional and horizontal wells. Specific problems associated with directional/horizontal drilling such as torque, drag, hole cleaning, logging and drill string component design are included.
    The course offers a strong overview of rotary steerable tools and their application. Finally exercises are used to deepen the understanding and allow a better hands-on participation.

    Course Level: Skill
    Duration: 5 days
    Instructor: Catalin Teodoriu

    Designed for you, if you are...

    • A drilling, production or operations engineer, field supervisor, toolpusher, manager or technical support person

    How we build your confidence

    You will receive instruction on planning and evaluating deviated and horizontal wells and learn how to perform simple calculations associated with well survey. The basic applications and techniques for multi-lateral wells are also covered in the course.
    A strong focus will be on the tools and techniques used in directional drilling such as survey instruments, bottomhole assemblies, motors, steerable motors and steerable rotary systems.
    As an independent course, it offers the most complete overview of geo-steering tools.
