An Interactive 5-Day Training Course
Work-over and Completion Operations
Planning, Execution and Troubleshooting
Course Overview
Workover is performed after the initial completion to re-establish commercial production or injection, repair of a mechanical problem in the well, or plug and abandon the well. Workover operations are usually initiated as hydrocarbon production rates decline substantially. Undesired fluid production could be the result of a poor primary cement job or water / gas coning. These workovers typically involve a remedial cement job to control the unwanted water / gas production.
Well completion is performed at the completion of drilling operations to establish initial production from or injection into a well. Procedures of completion will vary depending on the completion type and the area. For Example flowing wells can simply be perforated and put on production. Low reservoir pressure areas often require an artificial lift mechanism (rod or submersible pump, gas lift valves, etc.) to produce at economic rates.
