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. It will cover common problems in horizontal wells used for shale exploitation
Course Structure: 8 modules of 2 hours each, delivered over 4 days Each day will consist of 2 modules which will be no more than 2 hours in length with multiple breaks.
Course Level: Skill Duration: 4 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
The course is constructed as a live instructor-led training with case studies, videos, and exercises presented during class.
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.
