What term describes operations on a producing well to restore or increase production, including possible repairs or cleaning?

• A. Recompletion
• B. Stimulus
• C. Acidizing
• D. Workover

Answer: (D)

Workover refers to a broad set of operations on an existing producing well aimed at restoring or increasing production, including repairs and cleaning. This can involve pulling the tubing to fix or replace downhole equipment, repairing pumps or valves, cleaning out scale, paraffin, or other deposits, removing obstructions, fishing for stuck tools, and sometimes reconfiguring or reentering the completion to improve flow. Because it covers the wide range of maintenance and remediation tasks needed to bring a well back to optimal production, it best fits the description. Other terms describe more specific actions: recompletion focuses on producing from a different interval or zone, while acidizing or other stimulation treatments are targeted methods to enhance permeability or flow. Those are not the general, all-encompassing repair-and-cleaning operations described here.
