Well completion is considered to be one of the most critical practices for reservoir exploitation and management. During this process, the responsible personnel is tasked to optimally design and install a system that can deliver its full potential to optimize oil, gas and production without compromising safety and reliability. During the field life cycle, some reservoirs undergo some physical and chemical changes. This leads to loss of revenue as the wells are no longer operating at their optimal conditions. Hence, workover and well intervention practices are required to safely and efficiently restore the wells back to production.

This course focuses on different technological innovations to optimize reservoir drilling and completion practices, to improve well productivity. It provides practical exercises and industrial applications from different operating environment (land, swamp, offshore, including deepwater offshore).
It covers different types of completion design and installations. In addition, in-depth discussions on the emerging techniques would be covered.



  • Identify and understand the parameters that influence the selection and design of completion components.
  • Integrate the importance of completion process to future production.
  • Deliver techniques to select the best tubing size and best materials for well completion.
  • Gain practical methods to design, plan and install safe and efficient well completion and workover.
  • Manage well environments with extreme reservoir conditions (pressure, temperature, etc)
  • Bridge the importance of well design in relation to the ability to carry out well intervention.
  • Explore new technological developments in well completions and workovers.
  • Plan an appropriate intervention and workover strategy to maintain or increase the field production.
