| 201 | Oil well blow-out safety system | US90487 | 1979-11-01 | US4316506A | 1982-02-23 | Douglas Poole |
| A system for delaying the ignition of, or for extinguishing, an oil well rig fire, by injecting an admixture of for example pressurized CO.sub.2 and mono-potassium phosphate into the flow of hydrocarbons from the drill pipe and casing, through a plurality of holds in the wall of a spool apparatus located in the "stack" above the "Hydril" and blow-out preventers and above the casing but preferably below the mud return line element. The spool apparatus is equipped with a plurality of one-way check valves for receiving a plurality of conduits or chicksaw lines for transporting the chemicals from storage tanks to the spool apparatus. The entire system can be manually activated by a spring-loaded mechanism at the control head. Additionally, the system can be used to inject, for example, ammonium hydroxide to neutralize highly toxic gases, known as "sour" gases, arising during a blow-out. | ||||||
| 202 | Thermal safety valve | US679974 | 1976-04-26 | US4069834A | 1978-01-24 | Edward C. Bern; Donald B. Gemeinhardt |
| A thermally activatable safety valve apparatus is provided with a timing assembly and valve means operationally associated with the timing assembly. First and second fluid transmission means are provided through the apparatus, with one of the first and second fluid transmission means being isolatable by activation of the timing assembly. A thermally activatable trigger means isolates the other of the said first and second fluid transmission means and also initiates the closure of the valve means associated with the timing assembly. Upon activation of the present thermal safety valve, control fluid upstream of the apparatus is isolated from the transmission line downstream of the apparatus, and downstream control fluid is permitted to dump through the apparatus for a predetermined period of time, at the conclusion of which the said valve means associated with the timing assembly completes closure which isolates the downstream control fluid, whereby the hazards of additional and potential fire fuel are greatly reduced. | ||||||
| 203 | Cryogenic control valve | US16833171 | 1971-11-26 | US3857255A | 1974-12-31 | PATTERSON J; ELWOOD A |
| A cryogenic control valve for regulating the flow of material, such as a gaseous or liquid fluid, through a conduit. The control valve includes a jacket connected to the conduit, an input pipe with one end connected to a source of a low-temperature coolant, and control means to control the movement of the low temperature coolant to convert at least a portion of the fluid material in the conduit into a solid state to regulate the flow of the material through the conduit.

| 204 | Method of extinguishing oil and gas well fires | US21384371 | 1971-12-29 | US3856088A | 1974-12-24 | FRISQUE A |
| Oil and gas well fires may be extinguished by injecting into such wells below the fire a stable liquid dispersion of a water soluble anionic vinyl addition polymer and a water soluble cationic polymer, and then inverting this liquid dispersion in the well to produce a three-dimensional water and hydrocarbon liquid insoluble gel-like structure which seals off said well; thereby extinguishing said fires.

| 205 | System of firefighting and blow-out protection for a drilling operation | US27095672 | 1972-07-12 | US3804175A | 1974-04-16 | MILLER D |
| A system of fire fighting and blow-out protection for a drilling operation comprising valves and flow conduits interconnecting a low pressure and a high pressure source of inert gas to the interior of a blow-out preventer assembly. A pneumatically actuated valve connected to the blow-out preventer outflow conduit is moved to the closed position upon a predetermined pressure being effected by the flow of inert gas therewithin. Gaseous hydrocarbons leaking from the blow-out preventer are rendered noncombustible by admixing an inert diluent therewith by moving a flow control valve to a first position. Should the situation deteriorate into a more dangerous condition, the valve can be further opened whereupon a high pressure source of inert gas is flow conducted into the blow-out preventer while at the same time the outflow valve from the blow-out preventer is moved to the closed position, thereby setting the rubber of the blowout preventer assembly and increasing the effective hydrostatic head of the borehole, as well as lowering the inflammable limits of the escaping gaseous hydrocarbons.

| 206 | Explosive-proof method and incinerator for burning drill cuttings | US3658015D | 1970-04-15 | US3658015A | 1972-04-25 | GRIFFIN PHIL; PHILLIPS WILLARD C |
| An incinerator for removing hydrocarbon residues and other organic and inorganic components from oil and gas well drill cuttings is submerged in water to make the assembly explosiveproof with respect to the drilling rig. One embodiment uses a basket with a removable bottom in the cumbustion chamber to retain the cuttings during the burning. An alternate embodiment uses a series of metal plates for such retention. After burning, the pollution-free cuttings are discharged from the combustion chamber beneath the surface of the water to eliminate sparks which might otherwise also cause an explosion. A belt-driven scoop located beneath the cumbustion chamber provides a means of testing the burned cuttings for unburned pollutants.

| 207 | Method for controlling well blowouts | US3647000D | 1970-04-16 | US3647000A | 1972-03-07 | ROWLEY KERMIT G; BARRON RICHARD H |
| Uncontrolled flow of oil and gas from petroleum wells located in a body of water, is stopped by a procedure performed below the water surface at a location which is free from wave action and is safe from the danger of fire or explosion. An access conduit line is hot-tapped into the production tubing through access windows formed in the well casing. The production tubing is then crimped above the hot tap and solid particles are then introduced into the production tubing through the access line where they are carried upwardly by the flowing well fluids to lodge within the restriction and form a plug. Heavy, noncombustible ''''mud'''' is then pumped into the tubing through the access line until the weight of the injected mud overcomes the formation pressure, thus terminating well flow. Where the well is located on land, the method of the present invention may be practiced by obtaining access t the well structure at the point below the land surface for formation of the hot tap and crimp.

| A METHOD AND APPARATUS FOR COOLING EXHAUST PIPES OF INTERNAL COMBUSTION ENGINES WHEREIN CARBON DIOXIDE, SOTRED IN LIQUID STATE, IS DISPENSED THROUGH A NETWORK OF CONDUITS AND RELEASED IN OR AROUND EACH EXHAUST PIPE TO COOL THE PIPE PREVENTING FIRE WHEN COMBUSTIBLE FLUID COMES INTO CONTACT THEREWITH.
