Well Design – Special Wells

An integrated course that covers complex well design considerations presented by environments like Ultra HPHT, High Sour, Extended Reach and Deep Water. The course aims to cover every aspect of well design and architecture and focuses on key critical engineering considerations for successful design and execution of wells in such environments.

Day 2:

  • Understand and analyse the fundamental challenges associated with high pressure and high temperature well designs
  • Delve into various design elements required for sound well architecture and material selection
  • Kick tolerance, cementing, Narrow margins, temperature considerations
  • HPHT well design exercise

Day 3:

  • To understand and analyse typical challenges associated with ERD wells like hydraulics and hole cleaning, torque and drag, wellbore stability, equipment selection
  • Casing wear, Fatigue, casing/liner floatation, slide/rotate (part string), wellbore tortuosity and drag, wellbore stability, maximize horizontal reach
  • ERD well design exercise

Day 4:

  • To gain understanding of high sour wells challenges and include these aspects into well design, material selection and qualification, NACE testing requirements

  • High sour well design exercise

Day 5:

  • Understand and analyse the well engineering challenges and difficulties presented by Deep Water environment.
  • Deep Water wells basis of design, key risks/hazards, subsea well heads and casing strings
  • Cementation – narrow margin window, kick tolerance, trapped pressure due to TOC or due to barite sagging
  • Deep water well design exercise
  • Post assessment, feedback and certificates
