ABSTRACT:
In accordance with illustrative embodiments of the present invention, an oil well fire fighting vehicle includes a reciprocated cable mechanism to cut off damaged well casing above ground level, and a slot region and gripping members that attach the vehicle to the cut-off casing when the vehicle is positioned thereover. A diverter deflects the oil flow away from the front of the vehicle, and a packer and valve assembly are forced down into the casing to pack-off the same and confine the oil flow to the valve which can be closed to shut in the well. Various heads for controlling the flow of oil from the well also are disclosed.
