E-415 - Practical Aspects of Well Planning & Costing

10 jours FOR/PAWPCE
  • Young engineers, drilling and completion superintendents already, or about to be involved in well design and planning
  • To provide a comprehensive overview of all steps one should take to properly plan and budget oil and gas exploration or development wells, from pre-planning with geoscientists all the way to delivery
  • To review the different parameters involved in oil or gas well planning
  • To identify major concerns and plan for dealing with them
  • To understand procedures and methods for designing oil or gas wells and preparing drilling programs
  • To learn how to estimate drilling time and costs, along with corresponding margins of error
  • To grasp importance of effective well engineering and planning
  • To follow efficiently well planning and costing sequences
