ABSTRACT:
Fires in oil wells are contained by placing a pipe ring containing selectively located and aimed spray nozzles around a burning oil well by a self-propelled vehicle that includes a controllable boom for raising and lowering the pipe ring and a pump to supply liquid carbon dioxide to the spray nozzles to form a substantially cylindrical or conical volume of liquid carbon dioxide around the oil well. The spray excludes oxygen from the region inside the cylindrical volume and the fire is extinguished by lack of oxygen as it is cooled. Some of the spray may be directed away from the pipe ring to cool heated objects near the fire. In one embodiment of the invention, a ring containing spray nozzles is moved by a walking boom to surround and put out a fire in a well in which the flow rate is relatively high. In another embodiment a fire in a well in which the flow rate is less may be put out by a containment cap containing spray nozzles that is placed over the fire by a boom attached to a vehicle such as an articulated loader to spray the fire.
