Well Architecture & EquipmentDRIL/ARCHIE

Who should attend?

  • This course provides a thorough and practical understanding of the methodology for designing a casing program.
Audience :
  • Young engineers, tool pushers, supervisors, other professionals involved or interested in well architecture.

Level : Foundation

Course Content

  • DRILLING & CASING PROGRAM

      • Role of casings.
      • Parameters to be considered to determine well architecture:
      • Well type.
      • Pore and frac pressures.
      • Completion, lithology.
      • Different types of casings:
      • Surface.
      • Intermediate.
      • Production.
  • WELLHEAD

      • Different elements.
      • Wellhead assembly sequences.
  • CHARACTERISTICS OF CASINGS

      • Geometric, physical and mechanical properties of the pipes, the connections.
      • Use of Drilling Data Handbook.
  • SHOE POSITIONING

      • Hypotheses to be considered, casing point - Kick tolerance.
      • Casing point - Kick tolerance.
      • Examples and exercises.
  • CASING STRING CALCULATION

      • Principles and assumptions to remember for the different strings.
      • Stress cases study:
      • Collapse.
      • Burst.
      • Tension.
      • Triaxial study.
      • Safety factors.
      • Casing selection: examples and exercises.
  • CALCULATION EXAMPLES

      • Case studies and writing of a spreadsheet in order to determine the casing point, the kick margin, the pressure max…
  • KNOWLEDGE ASSESSMENT

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,
  • select the casings as per the constraints encountered while drilling,
  • choose the right wellhead with regard to the casings used.

Ways & Means

  • Exercises.
  • Application to a real case (project) for participants in the “Drilling & Completion Engineering” training course (page 154).
