A wireline junk basket, when paired with a gauge ring, efficiently performs two tasks in a single run. When running tools and completion equipment with an outer diameter close to the internal diameter of casing or tubing, it's crucial to maintain a clear path to prevent operational issues. Even small amounts of debris can cause severe damage to equipment or, in the worst case, result in the equipment becoming stuck, leading to expensive and complicated fishing operations. In this setup, the wireline junk basket collects debris through its bottom opening as it runs in the well, trapping it inside the tool. The gauge ring scrapes off any debris (like cement or scale) from the casing or tubing walls, ensuring a clean and unobstructed path. As the tool moves upward, the basket seals against the rod, capturing the debris. The gauge ring is always sized slightly larger than the outer diameter of any equipment that will be run afterward. This tool combination is typically used alongside a gamma ray or casing collar locator to monitor smooth tool movement and provide accurate depth control.
