Who should attend?

  • This certifying training aims to provide the necessary knowledge to plan and carry out a directional drilling (geothermal, water, storage, oil, gas), including the architecture.
Public :
  • This certification is intended for technicians, tool pushers, site managers, supervisors, superintendents and engineers who will be involved in oil/gas drilling operations.

Level : Foundation

Learning Objectives

  • Upon completion of the course, participants will be able to:
  • calculate different casing strings using the Drilling Data Handbook,
  • select the right position of casing shoes,
  • calculate the stress applied to the casing pipes,
  • choose the right wellhead with regards to the casings used,
  • know the equipment needed for directional drilling,
  • design a directional well,
  • calculate the trajectories of a deviated well in 2D,
  • design the drill stem adapted to the well’s profiles to reach a target,

Ways & Means

  • Exercises.
  • Movies.
  • Work in groups, teamwork.
  • Computer use for the design of a personal spreadsheet program.
