Cementing under Extreme Condition of HPHT Wells


Description

This 2-day course will cover different theoretical aspects of High Pressure High Temperature (HPHT) and introduce the unique aspects and issues surrounding HPHT cementing. By the end of the course, participants should be able to:

  • Gain a general understanding of HPHT principles
  • Recognise the cementing challenges in HPHT wells
  • Identify fit-for-purpose cement solution in HPHT wells
  • Understand laboratory testing and gap analysis (API and Non-API procedures)

Why Attend?

Cementing is the backbone of the drilling operations; it is of a paramount importance and must be looked at very seriously by the oil and gas industry to avoid any catastrophic incidents.

Who Should Attend

  • Drilling and completion engineers
  • Petrophysicists engineers
  • Production engineers
  • Well integrity engineers
  • Oilwell cement professionals
  • Any individual who would like to learn about cementing HPHT wells
