Course Description


This GLOMACS Directional, Horizontal and Sidetrack Drilling training seminar 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 GLOMACS training seminar 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 GLOMACS training seminar 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 GLOMACS training seminar, participants will be able 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

Training Methodology

This GLOMACS Directional, Horizontal and Sidetrack Drilling training seminar will utilise a variety of proven adult learning techniques to ensure maximum understanding, comprehension and retention of the information presented. The daily workshops will be highly interactive and participative.

Organisational Impact

The organisation will gain, in sending their employees to attend this particular GLOMACS training seminar, the following:

  • Achieving the optimum design of well, and avoiding the risk
  • Extending the well life and control it
  • Ensuring the well integrity in all stages

Personal Impact

  • Obtain integrating knowledge to mitigate and eliminate the drilling problems
  • Hone their knowledge and get the self-confidence for doing the proper well design, in addition, how to eliminate all kinds of problems


This GLOMACS training seminar is suitable to a wide range of professionals but will greatly benefit:

  • Drilling Engineer
  • Completion Engineers
  • Completion Supervisors
  • Drilling Managers
  • Drilling Technical Support Personnel
