What is the term for operations on a producing well to restore or increase production?

• A. Workover
• B. Recompletion
• C. Drilling
• D. Stimulation

Answer: (A)

Restoring or increasing production from an existing producing well is called a workover. This broad term covers a range of interventions performed without drilling a new well, such as repairing or replacing downhole equipment, cleaning the wellbore, fishing for stuck tubing, altering the completion, perforating or re-perforating, and applying stimulation or chemical treatments as needed. The idea is to rework the well to bring it back to higher production or to extend its life. Stimulation, for example, is a specific type of intervention focused on improving flow by enhancing reservoir or wellbore conductivity, and may be part of a workover but doesn’t by itself define all such interventions. Recompletion involves changing the completion to produce from a different interval, which is a more narrow operation within the broader workover. Drilling, by contrast, is about creating a new well, not performing work on an existing one.
