Abstract
A wireline apparatus and method has features that prevent the wireline from moving with respect to the drill string due to drill string movement or wave action on the drill rig. The apparatus includes a frame having a wireline pressure sealing device. The pressure sealing device is mounted to the top of the drill string. A drum is rotatably mounted to the frame on the side of the pressure sealing device. The drum is powered by a hydraulic motor and controlled by a remote unit. Wireline is wrapped around the drum and reeved over a sheave which is mounted to the frame near the top of the wireline sealing device. A lift sub is secured to the top of the frame and enables the frame to be lifted by the rig elevators. The frame provides a linkage between the elevators and the drill string to lift the drill string.
