This course provides an introduction and overview of key considerations in well completion and workover design, and a fundamental explanation of well/service equipment and operations. Technical explanations of common practices are given, along with troubleshooting hints. Completions in a variety of settings, including HPHT, deepwater, and resource plays, are considered. 

Duration and Training Method

This is a three-day classroom course comprising lectures illustrated by examples, videos, and case studies.

Participants will learn to:

  1. Describe the fundamental concepts of well completions, including the completion design process.
  2. Understand the differences between risk and uncertainty in petroleum engineering.
  3. Recognize the factors that influence well performance and identify options to mitigate problems.
  4. Identify the various types of stimulations and workovers.
  5. Recognize the key components of well, workover, and intervention equipment.
  6. Review stimulation and workover methods.
  7. Discuss best practices for workovers and interventions.
