Description

DESCRIPTION

Well Intervention is a very important area of petroleum & production engineering that covers all the methods to repair a well in order to keep it under safe production and profitable status.
The efficiency of coiled tubing services has significantly improved during the last two decades and is today utilised on a large scale of applications, as a result of the increased understanding and enhanced capabilities, which have been provided by research, innovation and development efforts.
It is common that each company publishes its own CT manual, where guidelines are provided, incorporating technical, operational and safety information for all related rigless operations, focusing on bes…

DESCRIPTION

Well Intervention is a very important area of petroleum & production engineering that covers all the methods to repair a well in order to keep it under safe production and profitable status.
The efficiency of coiled tubing services has significantly improved during the last two decades and is today utilised on a large scale of applications, as a result of the increased understanding and enhanced capabilities, which have been provided by research, innovation and development efforts.
It is common that each company publishes its own CT manual, where guidelines are provided, incorporating technical, operational and safety information for all related rigless operations, focusing on best practices.
CT is an excellent tool that opened new horizons for important well intervention with rigless operations: stimulation, production logging, well kick off, scale removal, fill cleaning, water/gas shut-off, plugging and abandoning, fishing, etc.

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

DESIGNED FOR YOU, IF YOU ARE...

A petroleum or production engineer, a development geologist, reservoir modeller or field engineer who wants to develop your knowledge on Wireline Well Intervention and CT Operations and Equipment.

HOW WE BUILD YOUR CONFIDENCE

By attending this course under seminar style teaching, you will be focusing on all main types of well interventions, CT equipment and main applications of this technology.

THE BENEFITS FROM ATTENDING

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

  • Well Intervention techniques and the fundamentals of Wireline and CT operations and all applications on well repairing and boosting production efficiency
  • All main types of well interventions, CT equipment and main applications of this technology.
  • Equipment, how it works and the importance of selecting the applicable well intervention strategy and CT applications in miscellaneous rigless operations.
