With the pass the time the activities of well workover acquire each be important, is not equal drill a well where the economic investment of the project is biggest, where at the same time be need approval of exploration and production permits as well as environmental permits and the complexity that means drill a well itself, that carry out the workover of one.
No way I want that you interpret that the workover operation is easy, no, this operation is complex and a lot diverse, but however in cost is minor
Workover Rig: Is a rig used to perform one or variety of operations on a producing oil and/or gas well to try increase production.
Tongs: Large wrenches used to make up or break out drill pipe, casing, tubing or other pipe.
Tubing Job: Is the act of the pulling tubing out of and running in back into well
Rod Job: Is the act pulling rods into and out of the wellbore.
Workover: Solve internal damage in the process after a certain period of useful life of the well or production, after completion.
Rehabilitation: Improve production and/or injection capacity
Recompletion: Abandon a current deposit that has become unproductive or has declined in useful life, completing the well in another productive area that is more attractive than the previous one.
Production to Injection: When the deposit enters a stage of secondary recovery and it is required to give an energy boost to the deposit.
What’s the fundamental reason for doing a workover?
Increase or restore hydrocarbon oil and gas production
Decrease water production
Repair mechanical failures
The workover operations is an activity that day for day achieve more important inside of the oil and gas recuperation.
Workover Process
Ideally Rods and Tubing would be perfectly straight but they are not.
Rod jobs and Chewing Jobs are both examples ongoing well maintenance, both the rod and tubing reached to the bottom of the well which could be thousand of feet deep as the pump jack moves it lifts the rod up on down anywhere from 5 to 25 feet
This movement may cause wearing to the rods or the tubing including broken or unscrewed rods and in holes in the tubing
Conclusion
Workover Rig: Is a rig used to perform one or variety of operations on a producing oil and/or gas well to try increase production.
What are the stages of a well after of the drilling: Completions, Primary Repair, Secondary Repair, Interventions and Abandonment.
What’s the fundamental reason for doing a workover: Increase or restore hydrocarbon oil and gas production, Decrease water production, Repair mechanical failures
