Introduction:
Well oil and gas workover is performed after the initial completion of commercial production or injection, the repair of a mechanical problem in the well, or the plugging and abandonment of the well. The oil and gas workover and completion operation will begin as hydrocarbon production rates decline significantly.
Undesired fluid production could result from a poor primary cement job or water/gas coning. These workovers typically involve a remedial cement job to control the unwanted water/gas production. Understanding the meaning of oil and gas workovers is key for anyone involved.
After drilling operations, an oil and gas workover and completion of operations will be performed to establish initial production from or injection into a well. The completion procedures will vary depending on the completion type and the area.
For example, flowing wells oil and gas workover can be perforated and put into production. Low reservoir pressure areas often require an artificial lift mechanism (rod or submersible pump, gas lift valves, etc.) to produce at economical rates.
Through extensive oil and gas workover training, participants have gained practical insights into what a workover entails. By addressing the question, "What is workover in oil and gas?" the course has clarified the essential processes and techniques involved in oil and gas workover operations.
Participants will have the knowledge and skills to manage workover operations in oil and gas effectively, ensuring these critical tasks' efficiency and safety. The training emphasized the importance of completion and workover operations, highlighting their role in maintaining and enhancing oil well productivity.
