ABSTRACT:
An electrically powered oil well pipe extractor includes a standard well servicing rig having a winch driven by a combustion engine. An auxiliary vehicle has an electric motor connected through a transmission or torque convertor, through a drive shaft, to the winch on the well servicing rig. The combustion engine is disengaged from the winch and the winch is driven by the electric motor on the auxiliary vehicle during pipe extraction operations at a well site having electric power available. Exhaust emissions and noise are significantly reduced.
