Well Integrity Technologies (PRE17)

  • 19-23 June 20235 daysVienna, AustriaCourse Fee: 3450 EUR + VAT


This course covers the main aspects of Well Integrity, starting with the construction of the well. Keeping the well operation within the safety envelope is critical for any oil & gas operator (well integrity technologies).
Well integrity technologies, focusing on monitoring problematic wells, diagnosing the causes of those problems, and implementing techniques to mitigate and/or repair those problems in order to keep the wells operating safely.

Course Level: Advanced
Instructor: Antonio Abreu, Luis Remisio, Cipriano Costa

Designed for you, if you are...

  • Petroleum engineer
  • Production engineer
  • Drilling engineer
  • Completion engineer
  • Oil field technical staff

How we build your confidence

  • The course will be presented using properly designed slides, some with animation and several videos on relevant issues.
  • Several examples of actual Well Integrity investigation will be presented.

The benefits from attending

By the end of the course you will feel confident in your understanding of:

  • The fundamentals of well integrity monitoring, and all implications on production efficiency
