Reed, M R; Hoffman, D E

Apparatus for the control of a well fishing line and operable at a location substantially above the wellhead to enable accommodation of cable mounted well tools, line weights, and the like. The apparatus incorporates a cable engaging drive wheel with a reversible hydraulic motor in direct-drive relation with the drive wheel. A pressure roller is in opposed association with the drive wheel and, through a hydraulic cylinder unit, is manipulable to vary the pressure engagement of the cable with the drive wheel for enhanced control of both the introduction and withdrawal of the cable. Both the hydraulic motor and the hydraulic cylinder unit are operable from a remote control station, normally at ground level, for a continuous monitoring of the apparatus notwithstanding its elevated location relative to the wellhead.
