ABOUT THE COURSE

The Completions and Workovers Blended Program represents one of the most popular foundation series courses within PetroSkills’ production engineering curriculum. Participants will become familiar with many aspects of modern completion design as well as a variety of workover technologies. This course is intended to be broad based, and includes both conventional and unconventional wells. The focus of this program is on design and selection.
