Wireline
Wireline is a crucial service in oil and gas operations that involves lowering specialized tools and equipment into oil wells using a steel cable (called a wire). Think of it like a very sophisticated fishing line, but instead of catching fish, it's used to gather information about the well, fix problems, or help with oil production. This technology helps oil companies understand what's happening deep underground and maintain their wells without having to remove all the production equipment. The term can refer to both the equipment itself and the service provided. Companies often use wireline services for tasks like measuring well conditions, fixing equipment, or adjusting underground valves.
