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 Distance Learning course will be scheduled as a series of three-hour long webinars over a three-day period, via 2 webinar sessions daily (equivalent to a three-day classroom course), comprising a mixture of lectures, discussions, and working examples

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.

Who should attend

This is course is intended for engineers, technologists, service personnel, and others involved directly or indirectly with the planning and programming of completion and workover operations.

Prerequisites and linking courses

There are no prerequisites, although a familiarity with basic reservoir engineering principles would be beneficial.

To further develop learnings from this course, participants might consider N940 (Modern Completion and Production Techniques), N083 (Petrophysics and Formation Evaluation: Principles and Practice), N607 (Petroleum Engineering for Non-Engineers), N422 (Reservoir Engineering for Non-Reservoir Engineers), N316 (Petroleum Geology for Non Geologists) or N614 (Fundamentals of Directional Drilling).

Michael Gallup

Mr. Michael Gallup is a Senior Production Engineer with over 12 years of experience in completion design and optimization of oil and gas wells, locally and internationally, which includes well test design and analysis, gas well dewatering, and well performance modeling.

He specializes in the construction and application of Integrated Production Models (IPM). These models link material balance, well performance and surface networks to form an overall production system model which is used to optimize field performance, enable production forecasting and monitor reservoir and well performance.

Michael also works on economic assessments and field development plans for both offshore and onshore fields located across the globe. Michael is a member of the Society of Petroleum Engineers (SPE), Engineers Nova Scotia, and a registered Professional Engineer with APEGA.
