Abstract
A fire control system for use at a well site for sensing the presence of a fire and for automatically placing into operation apparatus for mixing the fluid produced by the well with a fire control agent to extinguish the fire. Much of the fire control system can be located underground to protect it from a fire.
Claims17
A fire control system for use with a hydrocarbon extraction system of the type that extends underground and carries a hydrocarbon fluid stream to the surface, said fire control system comprising:
- at least one storage tank located at a site of the hydrocarbon extraction, at least one said storage tank is for storing a fire control agent;
- an injector for injecting the fire control agent into the hydrocarbon fluid stream so that the fire control agent is carried with the hydrocarbon fluid stream;
- and
- said hydrocarbon extraction system includes a pipeline that extends from an underground location, and said injector injects the fire control agent into the underground pipeline.
A fire control system for use with a hydrocarbon extraction system of the type that extends underground and carries a hydrocarbon fluid stream to the surface, said fire control system comprising:
- a storage tank located at a site of the hydrocarbon extraction, said storage tank for storing a fire control agent;
- means for pressurizing the fire control agent;
- an injector for injecting the pressurized fire control agent into the hydrocarbon fluid stream so that the fire control agent is carried with the hydrocarbon fluid stream;
- and
- a pump for pulsing the pressurized fire control agent into said injector.
A method of controlling conditions relating to a fire at a site of an oil or gas extraction operation carrying a hydrocarbon fluid stream, said method comprising:
- storing a fire control agent in a storage tank at the site;
- pressurizing the fire control agent and injecting the fire control agent into the hydrocarbon fluid stream;
- and
- carrying the hydrocarbon fluid stream and said fire control agent to a location of a fire for facilitating the control of the fire.
A fire control system for use with a hydrocarbon extraction system of the type that extends underground and carries a hydrocarbon fluid stream to the surface, said fire control system comprising:
- at least one storage tank located at a site of the hydrocarbon extraction, at least one said storage tank is for storing a fire control agent;
- wherein said at least one storage tank is located underground;
- and
- an injector for injecting the fire control agent into the hydrocarbon fluid stream so that the fire control agent is carried with the hydrocarbon fluid stream.
A fire control system for use with a hydrocarbon extraction system of the type that extends underground and carries a hydrocarbon fluid stream to the surface, said fire control system comprising:
- at least one storage tank located at a site of the hydrocarbon extraction, at least one said storage tank is for storing a fire control agent;
- an injector for injecting the fire control agent into the hydrocarbon fluid stream so that the fire control agent is carried with the hydrocarbon fluid stream;
- and
- a pump for pumping the fire control agent from said at least one storage tank to said injector, and wherein said pump is located underground.
A fire control system for use with a hydrocarbon extraction system of the type that extends underground and carries a hydrocarbon fluid stream to the surface, said fire control system comprising:
- at least one storage tank located at a site of the hydrocarbon extraction, at least one said storage tank is for storing a fire control agent;
- an injector for injecting the fire control agent into the hydrocarbon fluid stream so that the fire control agent is carried with the hydrocarbon fluid stream;
- and
- wherein said at least one storage tank is pressurized for forcing a pressurized fire control agent out of the pressurized storage tank to said injector.
A fire control system for use with a hydrocarbon extraction system of the type that extends underground and carries a hydrocarbon fluid stream to the surface, said fire control system comprising:
- at least one storage tank located at a site of the hydrocarbon extraction, at least one said storage tank is for storing a fire control agent;
- an injector for injecting the fire control agent into the hydrocarbon fluid stream so that the fire control agent is carried with the hydrocarbon fluid stream;
- and
- further including a pipe stub connected in line to a pipeline carrying the hydrocarbon fluid stream, said pipe stub equipped with a surge protector for reducing surge pressures above said surge protector.
A fire control system for use with a hydrocarbon extraction system of the type that extends underground and carries a hydrocarbon fluid stream to the surface, said fire control system comprising:
- at least one storage tank located at a site of the hydrocarbon extraction, at least one said storage tank is for storing a fire control agent;
- an injector for injecting the fire control agent into the hydrocarbon fluid stream so that the fire control agent is carried with the hydrocarbon fluid stream;
- and
- further including a pipe for coupling a fluid pressure from a pipeline carrying the hydrocarbon fluid to said at least one storage tank to force the fire control agent from said at least one storage tank.
A fire control system for use with a hydrocarbon extraction system of the type that extends underground and carries a hydrocarbon fluid stream to the surface, said fire control system comprising:
- at least one storage tank located at a site of the hydrocarbon extraction, at least one said storage tank is for storing a fire control agent;
- an injector for injecting the fire control agent into the hydrocarbon fluid stream so that the fire control agent is carried with the hydrocarbon fluid stream;
- and
- further including a programmed controller and a fire sensor located at a site of the hydrocarbon extraction system, said controller programmed to monitor said fire sensor and when a fire is detected at the site, said controller controls the fire control system to cause the fire control agent to be injected into the hydrocarbon fluid stream.
