ONLINE: Directional, Horizontal and Multilateral Drilling (DRI908)

  • To be announced for 2024


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: 10 modules of 2 hours each, delivered over 5 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: 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

  • 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.
