Introduction
Training course introducion / brief

This course provides information on how the completion progresses from a cased well to the point of having a well capable of production. The well will require perforating, equipment will be installed inside the casing, the productive formation may require treatment to enable production and the fluids may need assistance in getting up to the surface. After producing for a period of time, a workover may be necessary if the downhole equipment needs repair or servicing or the formation requires additional treatment in order to continue efficient production.

Course Objectives
At the end of the training course, participants will be able to

Trainee will learn what is involved in a well completion, how a completion is performed and the identification and purpose of some of the equipment and tools used in the well completion or workover.
