A workover is a maintenance or repair operation performed on an oil or gas well to restore, prolong, or enhance its production. Think of it like giving a car a major service - but for oil wells. When wells stop producing as much as they should, or have mechanical problems, workover crews come in with special equipment to fix these issues. This might involve replacing worn-out parts, cleaning out debris, or making adjustments to help the well produce better. It's a critical maintenance process in the oil and gas industry that helps keep wells productive and safe.
