The pulling tool includes a pump located in the tool housing for pulling drilling mud into the lower end of the pulling tool and discharging the drilling mud in an upward direction so as to provide a downward force on the logging tool and logging cables. Several pulling tools can be used at the same time, each being spaced at intervals along the logging cable.
