Directional, Horizontal, and Multilateral Drilling - DHD
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. Participants will receive instruction on planning and evaluating horizontal wells based on the objectives of the horizontal well. The basic applications and techniques for multi-lateral wells are covered in the course. Additionally, they will become familiar with the tools and techniques used in directional drilling such as survey instruments, bottomhole assemblies, motors, steerable motors, and steerable rotary systems. Participants will be able to predict wellbore path based on historical data and determine the requirements to hit the target.

Average rating 4.2
All subjects were given fair time. [Instructor] did a great job of responding to students' needs for more detail on certain subjects and less on others.
I appreciate the fact that [instructor] took his lunch time to explain the mathematics to me. Thanks!
The course was good and I was happy to be on the course.
