Audience

    • Young engineers, drilling and completion superintendents already, or about to be involved in well construction.

Level

  • Foundation
  • This course provides a comprehensive overview of all steps one should take to properly plan and budget Oil & Gas exploration or development wells, from pre-planning with geoscientists all the way to delivery.
Learning Objectives
  • Upon completion of the course, participants will be able to:
  • review the different parameters involved in oil or gas well planning,
  • identify major concerns and plan for dealing with them,
  • understand procedures and methods for designing oil or gas wells and preparing drilling programs,
  • learn how to estimate drilling time and costs, along with corresponding margins of error,
  • grasp importance of effective well engineering and planning.
