This training course will increase the participants’ understanding of the operations carried out by directional drillers and how directional and horizontal wells are planned and optimized. The basic applications and techniques for multilateral wells will be covered and participants will receive instructions on planning and evaluating horizontal wells based on the objectives of the horizontal well, and how to perform the proper planning for directional and horizontal well. In addition, this training course will cover how to predict wellbore path based on historical data and determine the requirements to hit the target, and help solve related problems.
This training course will feature:
- How to identify candidate wells for horizontal drilling, design horizontal and multilateral well profiles
- Understanding single and double build curve
- Calculating torque and drag
- Understanding kick off methods, compile a drilling and completion program and estimate wellbore stability mud weights
By the end of this training course, you will learn to:
- Interpret TVD, polar, rectangular coordinates, dogleg severity and the problems associated with it
- Interpret torque and drag and what factors affect those in the drilling process
- Understand main concepts associated to well path planning
- Recommend suitable measures to mitigate operational issues related to directional and horizontal drilling
- Understand main concepts associated to well construction of multilateral wells
