      • Course Description

        Once a well has been drilled to total depth, it must be decided whether it can be made to produce oil and gas in profitable amounts. Perhaps only one out of six wells drilled can ever produce enough petroleum to recover costs and offer profit. Even then, that one well must be completed properly. Recompletion costs are high, and a bad completion may ruin a well. Completion must be done right the first time.
        This E-Learning course is designed to provide participants with up-to-date overview of completions and workovers. The course covers the main factors influencing completion design, the overall approach to a well’s flow capacity, the major types of completion configurations, the main phases in completion, the drilling and casing the pay zone, evaluating and restoring the cement job, perforating, treating the pay zone, the special case of horizontal wells, the general configuration of flowing well equipment, the production wellhead, the production string or tubing, packers, downhole equipment, subsurface safety valves, servicing & workover operations on killed wells, servicing & workover special cases and well stimulation
