     BACKGROUND 
     The present invention relates to an apparatus and method to release energy and perform work with said energy release in a well system; more specifically, to release chemical energy in a well system utilizing at least one fluid transmitted down a continuous conduit disposed in a well or riser reacting said fluid across a subterranean catalyst to release energy in the well system. 
     More particularly a method to continuously supply a fluid to a down hole catalyst and apparatus for using the energy release of the catalytic reaction and any subsequent reaction of said fluid after the catalytic reaction to heat the subterranean environments claimed herein. This invention can also use said energy release to do useful work, such as but not limited to jetting perforations, drilling, cutting, welding, powering pumps, compressors, turbines, generators, or more simply heat well system fluids, pipes, subterranean reservoir fluids, subterranean solids, and completion devices in the well system. For example, the released energy can be used to cut a window in a casing for further down hole processing through such window or weld a junction in a multi-lateral well or otherwise create a weldment. 
     It is well known that the application of down hole energy in gas and oil well systems can be used to slot, or perforate, or cut off well tubulars. This is commonly done with high pressure water jets with abrasives or shaped explosive charges in the art of well perforating. 
     The use of abrasive fluid jets require large amounts of hydraulic horsepower to be generated on the surface and transmitted to the well depth required. Frictional losses in the transmission conduits, the accumulation in the well system of the abrasives, and the accumulation of the jetting fluid in the well system can provide limitations with existing technology. 
     The shaped explosive charges on the other hand release energy rapidly by means of a chemical reaction. These charges are ignited with various electrical and mechanical triggers. These explosive charges are very dangerous to transport, store, and handle on the surface and many people have been killed when the charges are set off on surface by accidental electrical excitation, like a radio being keyed up in the vicinity of the well where the explosives are being prepared on surface. Moreover, the explosive charges fire instantaneously such that they can only penetrate at a focused point in the well and hence many charges have to be used to penetrate various depths in the well system. Some explosive charges are not well suited for cutting slots, which yield more inflow area as is often required in wells that will require a gravel pack. This often means that many runs, for example runs of wire line deployed perforating guns, of explosive charges must be run in a well. Furthermore, the use of explosive charges, boosters, and the primer cord represents an extreme hazard to store and transport around the world. These charges, primer cord, and boosters can easily be used by groups that have evil intentions and hence the world wide use of explosive perforating in the oil and gas industry and the inherent storage, transport, and disposal of this explosive device represents a very difficult security challenge. These charges are very small and can be transported and concealed in shoes, toothpaste tubes, and many other stealthful methods. These explosive charges are used in hundreds of countries around the world, where oil and gas is produced and the continual monitoring of the storage sites and bunkers, the monitoring of their transport and movement becomes impossible. 
     The present invention allows for an improved method to transmit and release chemical energy down hole. The present real problem of security represented by the art of explosive well perforating is wholly avoided. Furthermore, the present invention can allow one trip down the bore to perform any service work involving perforating, avoiding the need for multiple trips down hole to perforate at different zones as bore hole conditions are experienced. Finally, the present invention solves the problem of high fluid friction losses present in current hydraulic jet cutting methods.

     DETAILED DESCRIPTION 
       FIGS. 1(   a ),  1 ( b ), and  1 ( c ), where like elements are indicated with like numbers, discloses a schematic of one embodiment of the present invention showing a bore  135  of a previously drilled and cased well system of, for example, an oil and gas well. 
     The term “well system”, as used herein, shall refer to any bore, well, or oil field drilling or production equipment. For example, a “well system” may include flow lines from well head to the host platform in a sub-sea well. 
     A conduit  100  is inserted into a well system which may be include traversing an injection head  105  and well head devices  115  (including a blow out preventor, etc.) as shown here. The conduit  100  may extend from a surface connection which, in  FIGS. 1(   a )- 1 ( c ), includes a conduit reel spool  110  located at a surface location. The proximal connection of the conduit  100  may also be secured to a wellhead hanger assembly (not shown), all in a manner well known in the art. A hydraulic seal  120  may also be used to prevent pressure loss from the well system. A data line  125  can be disposed either interior or exterior to the conduit  100  to connect a sensor  130  which can be affixed adjacent a distal portion of the conduit  100 , either externally or internally, to measure well conditions, for example temperature, flow rates, resistivity, or any of the other variables commonly measured in well systems in this art field. The sensor  130  can be a gamma ray recorder, a casing collar locator, a density neutron tool, or a distributed temperature sensor. The sensor  130  can be utilized to determine the location of the reaction chamber  140  within the well system, thus an operator may selectively commence the reaction to achieve a desired result. 
     At the distal end of the conduit  100 , a reaction chamber  140  is provided to house the reaction of any fluids and/or catalyst therein. In one embodiment, the fluid is injected into a conduit  100  by an optional pump  145  from a reservoir or tank  150  through an attachment to either the conduit  100  at the reel  110  or through a fitting in a manner well known in the drilling or coiled tubing industry. The fluid can include any reactant fluid that is decomposed with an exothermic reaction over a catalyst or that releases oxygen when decomposed over a catalyst. The fluid can be peroxide. Hydrogen peroxide is an example of a highly reactive yet widely available chemical that produces energy. 
     The term “energy”, as used herein, shall refer to the energy and/or heat released from a catalytic reaction and may include thermal energy. The released energy may include the decomposed reactant fluids. The energy can be released (“released energy”) for example in a reaction chamber or well system bore. If housed in a reaction chamber, the “released energy” may be selectively released therefrom as desired. The energy can be used as a heat source without releasing any of the reactant fluids from a reaction chamber  140 , for example radiant heating a well bore or formation fluid flowing adjacent an outside surface of the conduit  100 . The energy can be used to drive a turbine interior to the reaction chamber  140  or a motor (not shown) to provide either mechanical or electrical energy which can be used to perform work, for example to directly power a pump or compressor with the energy released from the reaction chamber or converting the energy released from the reaction chamber into mechanical or electrical energy which can power a pump or compressor. 
     An ignition device may also be located within the reaction chamber  140  to initiate the chemical reaction as needed. The conduit  100  may be concentrically disposed within a production or drilling tubular and/or used to heat or energize a fluid therein. 
     The injected fluid can further include a fuel, for example methanol, diesel, sugar, oil, or methane. The invention may include a second conduit (not shown) extending from the surface location to a fuel inlet port on the reaction chamber  140 . The energy and/or reactant fluid and/or fuel mixture can be jetted out through an energy focusing orifice  155  against a location of interest. Although two orifices  155  are shown, the invention may include one orifice or a plurality of orifices. An orifice can be disposed on the reaction chamber or the conduit. The orifice can be or include a jet, as is know in the art. 
     The reaction chamber  140  in  FIG. 1(   a ) is shown adjacent a first location of interest, for example a first hydrocarbon bearing zone  160 . The reaction of the fluid, for example hydrogen peroxide, can be assisted by the use of a catalyst  175  disposed in the reaction chamber  140 . The catalyst  175  can be wafer or granular. The catalyst  175  may be disposed in a well system and/or reaction chamber  140  on a wafer, screen, or body as is well know in the art of rocket science. The catalyst  175  can further be a solid or liquid. The catalyst  175  can be of any suitable type, preferably one that vigorously reacts with a reactant fluid, for example a peroxide such as hydrogen peroxide, to release energy. The catalyst  175 , for example, can be selected from the group of transition metals and transition metal compounds consisting of compounds of cobalt, manganese, silver, alumina, iron, palladium, rhodium, platinum, gold, and combinations thereof. Any metal oxide, for example iron oxide, may be a suitable catalyst  175 . A reaction chamber  140  is not required to use the same type or amount of catalyst as other reaction chambers, if present. 
     The design, volume, and/or shape of the reaction chamber  140  and/or catalyst  175  may be tailored for a particular application, for example the based on the amount and/or time of energy production desired. In the case of a stimulation or cleaning job, the amount of catalyst required does not have to last more than several hours, but in a permanent completion, a longer lasting catalyst or amount of catalyst  175  may be desirable. A catalyst  175  can be disposed down the conduit  100  while the reaction chamber  140  remains in the bore  135  of the well system using any means known in the art, which includes pumping a catalyst fluid mixture, using a liquefied catalyst, or physically inserting the catalyst with a well tool or other means. The energy released by the reaction of the fluid and catalyst  175  can be used to perorate an uncased section of the well system (not shown) or used against the wall of the well system bore  135  to perforate the wall, thereby releasing trapped hydrocarbons to flow up through the well system bore  135  to a production outlet  170 . The energy can be used down hole for jetting, cutting, welding, steam cleaning the well system, or stimulating the reservoir. For example, the energy released may be utilized to remotely weld, patch split casing or junctions, or cut junk in the well system. 
     The amount of energy produced and/or released can be controlled by any means known in the art, for example changing the size and/or shape of an orifice  155 , adding a valve to an exit port or orifice  155  for controlling the egress of reactant fluids and/or energy, or regulating the amount of fluid, fuel, and/or catalyst that is injected with the pump  145 . A data transmission, receiving, and collection apparatus  180  at the surface is shown schematically connected to a data line  125 . The data transmission, receiving, and collection apparatus  180  may be any kind known in the art, and is not limited to a single apparatus for all the transmission, receiving, or collection functions. 
     The conduit  100  may be a cold worked tube or a continuous tube, for example coiled tubing. The conduit  100  may also be a cold worked continuous tube or high nickel alloy, for example one having a composition of approximately 58% nickel, 20-23% chromium, 5% iron, 8-10% molybdenum, 3.15-4.15% niobium (plus tantalum), 0.10% carbon, 0.50% manganese, 0.50% silicon, 0.015% phosphorous, 0.015% sulfur, 0.40% aluminum, 0.40% titanium, and 1% cobalt, such as Inconel alloy 625 from Special Metals. Cold working the conduit  100  may increase the conduit&#39;s tensile strength without significantly reducing the corrosion or chloride stress resistance. 
     The conduit may include, but is not limited to, stainless steel, nickel, titanium, a high percentage nickel alloy, a super elastic titanium nickel alloy, all of which may be suitable for use in the caustic environment of a well system. A shaped memory or super elastic alloy may also be used, such as a titanium nickel alloys, to permit the manipulation of the shape of the conduit  100  after insertion into the bore  135  of the well system. The conduit  100  may include an optional unidirectional fluid check valve  133  at any point between the conduit and an entry port to the reaction chamber  140 . Each conduit  100  may be disposed with at least one unidirectional fluid check valve  133  to prohibit migration of reaction products, oil and/or gas through the conduit  100  to the surface. 
     In  FIG. 1(   b ), the reaction chamber  140  is shown in a second position adjacent a second zone of interest  165  in the bore  135  of the well system. The conduit  100 , and thus a connected reaction chamber  140 , can be moved before, during or after the energy is released. Either may be moved by any means known in the art, for example using the reel  110 , a hydraulic injector head, or otherwise acting at a surface location. A first set of perforations  185  are formed by the release of energy when the reaction chamber  140  is in the position shown in  FIG. 1(   a ). A formation or well fluid may then be produced out of surface tubing  170  if so desired. After the reaction chamber  140  is moved adjacent to the second zone of interest  165 , which may be a second hydrocarbon bearing zone, the energy can be released from the orifices  155  to form a second set of perforations ( 190  in  FIG. 1(   c )). Although the catalyst  175  is shown as substantially the same mass as in  FIGS. 1(   a )- 1 ( c ), it may decrease depending on the amount of fluid added and/or energy produced or released. 
     In  FIG. 1(   c ), the reaction chamber  140  is shown disposed near a proximal end of the bore  135  of the well system.  FIG. 1(   c ) illustrates the second set of perforations  190  in the second zone of interest  165  formed during the second energy release. Although each set of perforations ( 185 ,  190 ) is shown in pairs, the invention is not so limited. 
     To use the invention of  FIGS. 1(   a )- 1 ( c ), a conduit  100 , which may be disposed on a reel  110  that can have a slip ring that allows for fluid communication and data communication to be made with the inside of the reel  110  and the bore of the conduit  100 . The conduit  100  may have a data line  125  and/or sensor(s)  130  predisposed inside prior to arriving at the well system site. At the well system site, the conduit  100  may be threaded through an injection head  105 , hydraulic seal  120 , and well head device  115 , such as, but not limited to, work windows  116  and/or lubricator (not shown) located above a tubing hang off table, i.e. such that the conduit  100  may be inserted into the bore  135  of the well system. The various catalytic reaction chambers, down hole tools, turbines, motors, recorders, weight bars, etc. may be connected to the conduit  100  as it is run through the lubricator (not shown). 
     If a reaction chamber  140  and/or orifice  155  is connected above the bottom or distal end of the conduit, this attachment can be performed through a work window  116  and using blow out preventors and hydraulic seals. Any length of conduit  100  previously disposed in the well system may be hung with a temporary hanger or slip assembly while the different devices that will be located above the distal end of the conduit  100  are connected, for example a reaction chamber  155 , using welding methods or mechanical ferruled fittings. Once the conduit  100  is lowered to a desired depth in the bore  135  of the well system, a fluid, for example an 80% hydrogen peroxide and methanol mixture, may be injected from a surface location into a reaction chamber  140  and react with a catalyst  175 , if present. The fluid may be a mixture of a first fluid that reacts and decomposes over the catalyst  175  and a second fluid that reacts with a product formed by the catalytic decomposition of the first fluid. 
     The decomposed reactant fluids or energy may then exit an orifice  155  on the reaction chamber  175 . The orifice  155  can be positioned in the well system to apply the energy down hole for jetting, cutting, welding, steam cleaning the pipe, or stimulating the reservoir. A recovery fluid, such as an acid, can be pumped from the surface location into contact with the catalyst  175  to enhance or recover a portion of the catalyst&#39;s catalytic characteristics and/or prepare the conduit for the transport of a reactant fluid which may include hydrogen peroxide. For example, when using silver oxide as a catalyst  175 , one can periodically pump a recovery fluid such as nitric acid into contact with the catalyst  175  every 30 minutes to enhance, maintain, and/or recover at least a portion of the catalytic nature of the silver oxide. 
     The conduit  100  may be extracted from the well system while pumping the fluid from the surface. This may cut slots in the reservoir and/or casing of the well system or simply clean the internal diameter of the well system. The conduit  100  may be displaced while in the well system, which may cause a reaction chamber  140  to be moved up and down in the well system as required while the fluid is being pumped down from surface and decomposed and exiting the reaction chamber as energy. The conduit  100  may also be stationary while the fluid is being injected and/or pumped. This can allow the energy from catalytic decomposition to be used to heat the well system and/or the reservoir. 
     The conduit  100  may then be position at a second desired location in the well system such that the reaction chamber  140  is at a different level in the same well system to allow for the perforating, stimulating, and/or cleaning of another location. As shown in  FIG. 1(   b ), surface tubing  170  can be opened to allow the well fluid and/or the exhausted injected fluid (reactant fluid) to flow to the surface. One may also leave the surface tubing  170  closed so that the exiting decomposed fluids and energy would be injected into the reservoir. One skilled in the art of well completions and stimulation may both inject the energy released down hole by this invention&#39;s catalytic decomposition of fluid into the reservoir for extended periods of time, like in a steam injection cycle or an acid stimulation treatment, and then later allow the decomposed fluid and well fluid, as well as the energy released down hole in the well system by this invention, to flow to the surface. 
     Furthermore, a second fluid such as an acid, solvent, or a gas can be injected down the bore  135  of the well system through the surface tubing  170  with a reaction chamber  140  disposed adjacent a first reservoir  160 , or later dispose the reaction chamber  140  adjacent the first reservoir  160 . When the second fluid is at the reservoir depth it can be continually pumped and injected into the reservoir while the fluid, for example hydrogen peroxide, and other chemicals blended in the fluid pass through this inventions conduit  100  and reaction chamber  140  are exhausted into the second fluid to heat and gasify said second fluid prior to it entering the formation. This gives the reservoir an additional stimulation effect from the heat and the gas exhausted as energy from this inventions catalytic reaction. 
     The energy released by the invention&#39;s apparatuses and methods may allow a reduction in the diameter of a conduit  100  used within a well system bore  135 , to drill or clean for example, as compared to the typically sized drill pipe utilized with surface rotary rigs or coiled tubing drilling with down hole hydraulic motors powered by surface pressurized drilling mud, as less of the energy required down hole for the drilling or cleaning need be generated hydraulically at a surface location. 
     In  FIG. 2 , another embodiment of a conduit  200  is shown with multiple reaction chambers ( 240 ,  241 ,  242 ). A proximal end of the conduit  200  is connected to a reel  210  which can allow deployment and retrieval of the conduit  200 . A first  242  and second  241  reaction chamber may include a bypass  251  to allow the fluid to flow past a respective reaction chamber. The bypass  251  is not present, but may be included, on the reaction chamber  240  disposed on the distal end of the conduit  200 . A bypass  251  can allow a portion of the fluid pumped into the conduit  200  to by pass at least one reaction chamber ( 241 , 242 ) thereby not decomposing a portion of the reactant fluid across the catalyst  275  of said reaction chamber ( 241 , 242 ) while a portion of the reactant fluid may flow into at least one subsequent reaction chamber  240  and be decomposed across at least one catalyst  275  therein. Optional check valves  233  are shown in the conduit  200  upstream of each reaction chamber ( 240 - 242 ). 
     A fluid, for example hydrogen peroxide or other reactant fluid, is injected through the conduit  200  from the tank  250  by the pump  245  to an entry port of a reaction chamber ( 240 - 242 ). If present in a reaction chamber ( 240 - 242 ), a catalyst  275  may react with the fluid to release energy. The energy may be released from an orifice or exit port ( 255 ,  256 ) on the reaction chamber ( 240 - 242 ). The orifice  256  may be angled, for example angled upward to aid in the lifting of a well system bore fluid. Although a single orifice ( 255 ,  256 ) is shown on each reaction chamber ( 240 - 242 ), a plurality of orifices may be used.  FIG. 2  further shows two zones of interest ( 260 ,  265 ) with perforations ( 285 ,  290 ) which may have been formed by a previous release of energy. The conduit  200  may be rotated to allow different areas to be perforated or otherwise be contacted by the energy. The reaction chambers ( 240 - 242 ) may allow rotation by adding a swivel joint assembly (not shown) between the conduit  200  and reaction chambers ( 240 - 242 ) to allow the energy released from an orifice ( 255 ,  256 ) to rotate the reaction chambers ( 240 - 242 ). 
     An inner surface of a well system may be cleaned by releasing a small amount of small amount of energy, which may include a small amount of decomposed fluid, onto the well system bore  235 . The release of energy may also have the added effect of lifting any well system bore  235  fluid due to the energy added to said fluid from the catalyst, fluid, and/or fuel reaction. This may allow heavy oil to be moved up the well system bore  235  and optionally out the surface tubing  270  with less viscosity, a gas to be lifted with the energized reactant products (energy), a gas to be heated to eliminate or melt hydrates, or paraffin to be continually avoided or removed from the well system. The pump  245  can be adjusted to optimize the amount of fluids injected, the blends of the fluids pumped can be altered using additional tanks and a proportioner, and thus optimize the energy released, in the well system. One skilled in the art may use a timer or other controller to further optimize the fluid pumping rate and amount of time the fluid, for example hydrogen peroxide, is injected in a well system. It is further understood that this invention teaches the application of heating risers of offshore wells and/or pipelines with the use of single or multiple reaction chambers ( 240 - 242 ) disposed in or on the conduit  200 . 
     An optional second conduit  224  is shown extending from the surface location to an area adjacent the distal reaction chamber  240  and housing an electrical conductor  225 . The electrical conductor can be connected to an ignition source disposed within the conduit and/or reaction chamber. The electrical conductor can be replaced or accompanied by an optical wave guide like an optical fiber. The optional second conduit  224  can house an electrical conductor, an optical fiber, and/or other energy wave guide. The data transmission, receiving, and collection apparatus  280  can be a laser distributed temperature survey (DTS) machine. As is known in the art, an optical fiber  225  can act as a distributive temperature sensor by using optical time domain reflectometry (OTDR) backscattering of light interrogation methods with the DTS machine. OTDR and DTS are discussed in U.S. Pat. No. 5,163,321, hereby incorporated by reference. OTDR and/or DTS can be used to determine a temperature profile along a length of optical fiber  225 . The optical fiber  225  is used as a sensor to log the temperature along a length of the optical fiber, thus giving a surface indication of the reaction temperatures down hole and allowing the well system fluid heated by the exothermic reaction of the decomposition of hydrogen peroxide across the catalyst  275  to be tracked for velocity. By interrogating by light pulse, a temperature profile can be created for the bore  235  of the well system as the first conduit  200  is lowered or raised. By correlating the velocity of the heated fluid as it flows in the well system, and knowing the volume of the well system tubular the well fluid is flowing in, this method then becomes a flow meter with measurements at all points along the well. This allows one to discern the flow rates from different commingled reservoirs. The optical fiber  225  may also be run inside of the conduit carrying the fluid to be injected, as shown in  FIGS. 1(   a )- 1 ( c ). 
     Releasing energy at multiple points along a heavy oil well system may aid in steam and/or heat treating a well system as there can be a tremendous loss of energy when pumping steam in steam floods to the shallower depths. In the special case of Steam Assisted Gravity Drainage (SAGD), two parallel bore holes are drilled. One bore has steam pumped into it and the other allows the heavy oil to flow therein. This invention can be used in SAGD. A reaction chamber ( 240 - 242 ) can be run into either or both bores and using a first set of reaction chambers ( 240 - 242 ) disposed on a conduit  200  in the first bore to heat the reservoir and form the “steam chamber” in the reservoir where the heavy oil seeps into, and a second set of multiple reaction chambers ( 240 - 242 ) disposed into the second bore on its respective conduit (not shown) to lift the heavy oil from the second parallel bore, typically below the first bore, by gas lift type application with the added benefit of the heat reducing the viscosity of the heavy oil. 
       FIG. 3  is another embodiment for selectively releasing energy in a well system.  FIG. 4  is a sectional view of the sand screen  304  of  FIG. 3  along the line  4 - 4 . In this embodiment, the catalyst  375  is disposed inside the sand screen  304 . This sand screen  304  can be run off a drilling or work over rig as is common practice in the oil and gas industry, with a reel  310  of conduits ( 300 ,  301 ) shown banded to the outside diameter of the production tubing  370 . Additionally, the sand screen  304  may be constructed from and/or plated with a catalyst. 
     Although three sections of conduit ( 300 ,  301 ) are shown here, the invention can include one of more conduits. The conduits ( 300 ,  301 ) in this embodiment are connected on a distal end to the sand screen  304  by a wire wrap  306  and on a proximal end to a reel  310 , pump  345 , and a fluid tank  350 , which may include hydrogen peroxide. One conduit  300  includes an optical fiber  325  disposed therein. Optionally, a packer  302  may be used to help retain any fluid and/or energy below said packer  302  in the bore  335  of the well system. 
     In use, a fluid is pumped from the fluid tank  350  down at least one conduit ( 300 ,  301 ) from the surface into contact with the catalyst  375  in the well system. This energy release may occur anytime it is desired to cause the sand screen environment to heat up. The energy release may remove solids, heat heavy oil, or consolidate solids. The fluid, for example hydrogen peroxide, may be pumped from the surface down any conduit or a plurality of conduits ( 300 ,  301 ) and into contact with the catalyst  375  disposed in the sand screen  304 . A conduit ( 300 ,  301 ) can have at least one orifice  305  such that the fluid contacts the catalyst  375  disposed in the sand screen  304 , and not in the conduit ( 300 ,  301 ). As discussed in relation to  FIG. 2 , a flow meter may be formed by placing an optical fiber  325  in any conduit  300  such that the energy from the decomposition of the reactant across the catalyst is traced in the optical fiber  325  as heat. 
     Furthermore, a gravel pack may be used in the well system of bore  335 . The gravel pack may be created by the well known methods of pumping gravel. The gravel may be a gravel sized catalyst or a catalyst mixed with traditional gravel. 
     Similarly, a solid like sand, or in this case a catalyst ( 376 ,  377 ), may be blended into a slurry at the surface, pumped down a bore  335  of the well system through a crossover tool (not shown) such that the slurry circulates around the outer diameter of the sand screen  304  and the bore  335  of the well system. The fluid is then returned up the crossover tool (not shown) and bore  335  to the surface in a circulation such that the solid, in this case a catalyst  376 , filters out on the outside of the sand screen  304  and in the formation  360 . Then any one or all of the conduits ( 300 ,  301 ) may be used to inject a fluid, for example hydrogen peroxide, into the catalyst  376  disposed in the bore  335 . The slurry can further be used to pump the catalyst  376  out into the formation  360  under hydraulic fracture pressures disposing the catalyst  377 , as solids, into the fractures  303  as a proppant. The fluid, for example hydrogen peroxide, can also be pumped from an orifice  305  through the sand screen  304  and wire wrap mesh  306  out into the catalyst  377  in the fractures  303  to create energy. 
     The fluid may also be pumped into contact with the catalyst  375  disposed inside the sand screen  304  such that from time to time steam and/or heat can be generated from the catalytic reaction within the sand screen  304  to enhance cleaning of paraffin, scale, or other well residues from the sand screen  304 , gravel pack, and reservoir  360 . These escaping gases from the catalytic reaction in the sand screen  304  can also assist in lifting well system fluids to the surface, thereby enhancing the well system production while cleaning the well system for many years after the gravel pack completion has been deployed in the well system. This invention may aid in the mobilization of heavy oil reservoir fluids and lessen the need to go into gravel packed well systems to remedially clean them of scale, solids, and paraffin. 
     Referring now to  FIG. 5 , a schematic view of another embodiment is shown. The conduit  500  and a plurality of reaction chambers  540  are disposed inside the bore  535  of a larger well system tubular. Here, the energy released by the reaction of the injected fluid and catalyst  575  is exhausted and returned to the surface from an exit port  555  through a venturi or jet pump  556 . The jet pump  556  can aid the energy released to lift a solid and/or fluid to a surface location. A jet pump embodiment can be used to clean sand from a fracture job or unconsolidated sand from wells including horizontal wells as it robustly transduces solids as well as liquids. The jet pump embodiment can also be used to recover solids from great depths in well systems, such as in a riser extending from the sea floor. The venturi or jet pump  556  powered by the release of energy from the decomposition of the catalyst  575  and fluid may be replaced with a turbine or hydraulic motor, which may be at each reaction chamber, so that these machines extract work from the injected fluid and/or energy released from the catalytic decomposition of the fluid and any reaction thereafter of the reaction products with other fuels. The machines may be further used to power either a compressor or pump, allowing a reaction chamber&#39;s  540  energy to be converted into work and used to power down hole pumps and compressors, making this a multi-stage compressor or pump system without departing from the spirit of this invention. 
       FIG. 6  is another embodiment for using energy in a well system. Here a turbine drill bit  699  is disposed on a distal end of the conduit  600 . The bore  635  of the well system may be, for example, casing. The well system contains a plug  661 , which may be a drillable fracture, or frac, plug as known to those in the art. 
     The conduit  600  can be inserted from a reel  610  through well head devices  615  and a hydraulic seal  620  into the bore  635  of the well system. The turbine drill bit  699  is lowered into contact with the plug  661  via the conduit  600 . A fluid can be injected from the tank  650  with a pump  645  and into the conduit  600 . A single or plurality of reaction chambers  641  can be present. In the illustrated embodiment, the fluid passes a unidirectional fluid check valve  633  and may flow into a reaction chamber  641  and contact a catalyst  675 , if present. The fluid may also flow down the conduit  600  via a bypass  651 . The energy released by the fluid and catalyst reaction may be released from an orifice  655  on each reaction chamber  641  or released in the conduit  600  and into contact with the turbine drill bit  699 . Both reaction chambers  641  illustrate that an orifice  655  may be oriented in any direction, here angled upward to provide additional thrust for the turbine drill bit. The reaction chamber orifices  655  are not required to be similarly oriented as shown. 
     Work can be extracted from the energy released from a reaction chamber  641  to drive the turbine drill bit  699  or other motor. Optionally a weight tube  698  may be added to aid in drilling and/or disposition of the turbine drill bit  699 . The turbine drill bit  699  is shown after partially drilling the plug  661 . This embodiment can also utilize the heat from the energy exhaust products of the reaction chamber  641  to reduce the resistance to drilling out items in the well system bore  635 . 
     Similarly, energy released from an orifice  655  can aid the removal of solids generated by drilling to be lifted to a surface location. Additional energy may be added at various positions along the conduit  600  by including more reaction chambers  641 . Multiple exhaust orifices  655  from the more than one reaction chamber  641  may be advantageous in horizontal wells and in drilling in under balanced conditions. When one stops pumping during those drilling conditions, solids can be deposited around the drilling tube, in this case the conduit  600 , thereby causing the conduit to stick. This method of using various energy releasing orifices  655  to aid in the movement of fluids and solids can help reduce sticking. 
     The plug  661  may be drilled as discussed above or, if constructed so as to be meltable, removed by deforming the plug  661  or packer with energy. A plug  661  or packer may be a tin, brass, lead, or a plastic composite. The energy can be used to reduce the mechanical strength of drillable and/or retrievable devices for use in a well system bore  635  such as, but not limited to, plugs, packers, whipstocks, casing junctions, devices made with gas or fluid expansion chambers. Any of these well system devices may be constructed from metal, plastic, ceramic, or combinations thereof. The energy can be used to heat, melt, and/or expand well system devices, which may aid in retrieving or repositioning the devices in a well system bore  635 . 
     The level of energy released, which may only be partially released from a reaction chamber housing the “released energy”, is dependant on the decomposition of the fluid, which can be hydrogen peroxide, across a catalyst, and if any other fluids are added, a fuel for example. The energy can be released onto said plug  661  from an orifice (not shown) that is angled towards the plug  661  or no energy or decomposed fluid may be released from an orifice, but the heat from the energy may radiate through a reaction chamber  641  to melt or deform the plug  661 . A plug  661  may be constructed with fluid encapsulation chamber in the plug  661  such that the heat developed by the catalytic reaction of this invention causes expansion in the plug  661  which may unset a mechanical device and/or cause the plug  661  to self destruct due to the expansion. The plug  661  may be suitable for use during the hydraulic fracturing of multiple ( 660 ,  665 ) zones. Each zone ( 660 ,  665 ) can be perforated ( 685 ,  690 ), fractured, and/or have a plug  661  set across the zone with this invention without departing from its spirit. 
     Energy can aid in the lifting of a formation or well fluid, for example a gas.  FIG. 7  shows an embodiment of the invention whereby a fluid, for example hydrogen peroxide or a mixture thereof, can be injected from a tank  750  by a pump  745  through a reel  710  from which a length of conduit  700  extends. From the surface location, the conduit  700  enters a well system through well head devices  715  and into the bore  735  of the well system. The fluid is pumped into a reaction chamber  740  through an entry port. The aforementioned reaction chamber contains an exit port or orifice  755  attached to, and in fluid communication with, the inner bore of a length of production tubing  770 . The reaction chamber  740  can be a side pocket mandrel. A catalyst  775  can be added to the reaction chamber  740  during insertion of the reaction chamber  740  or after attachment to the production tubing  770 . 
     To use the embodiment shown, an optional gas lift or side pocket mandrel  730  may be present. If a gas lift mandrel  730  is present, a compressor  772  may be attached to a source of a gas  773  and injected into the well system bore  735  through a length of surface tubing  771 . The gas is sealed from contacting a reservoir  760 , shown with optional perforations  703 , by a packer  702 . The gas can be sealed from escaping the bore  735  by a hydraulic seal  720  on a proximal end of the well system and the packer  702 , thus the only outlet being the gas lift mandrel  730 . To aid in the lifting of a well system gas, the reactant fluid can be injected into the reaction chamber  740  into contact with a catalyst  775 , with the released energy flowing into the production tubing  770  through an exit port or orifice  755 . A plurality of reaction chambers  740  may be utilized. The energy can aid the movement of fluid upward though a jetting action and/or the decrease in density of the produced fluid when the reaction products are added. A catalyst  775  and/or reaction chamber  740  can be deployed into the gas lift mandrel  730  section of conduit  700  with standard wire line equipment or kick over tools. Although illustrated with a gas, the invention may be used with any fluid. 
       FIG. 8  illustrates another apparatus and method of the invention. Here, the energy can be used to heat, consolidate, or fuse a media or resin to the formation  860  to create a low permeability or impermeable barrier  861 . The media can be a solid such as tin or lead, for example. Exothermic heat from the catalytic reaction can be utilized by moving the reaction chamber  840  adjacent a portion of unconsolidated bore and allowing the energy, which may or may not include releasing any fluids from an orifice  855 , to exothermically melt and/or fuse reservoir  860  solids and/or fluids together. This can be achieved in an open hole section as shown in  FIG. 8  or through a cased section of the well system, as in the section adjacent a second reservoir  865 . 
     This invention&#39;s ability to control the down hole energy applied within a well system by changing the mixture of fluids and catalyst and/or moving the placement of the reaction chamber(s) allows for a plurality of fluids, solids, suspended solids in fluids to be injected into the reservoir and heated with this inventions down hole energy release methods yielding varying degrees of consolidation as a function of their melting and sublimation temperatures. The solids or suspended solids may be injected from a supply tank  872 , through a pump  871  and into the bore  835  through a well system connection conduit  870 . 
     As the invention allows the fluid, for example hydrogen peroxide, to be injected through a conduit  800  which can be located at any position in the well system while simultaneously moving the reaction chamber, or chambers,  840  connected thereto and releasing the energy from an orifice  855 , large sections of the well system can be consolidated rapidly even in horizontal wells. The energy liberated by the methods of this invention is not restricted to flowing in hydraulic fluid pathways in the reservoir  860 , often referred to as primary permeability. The liberated energy generated by this invention can radiate and be conducted in a homogenous front proceeding from the well system bore  835  outward. The conduit  800  can be moved, for example up and down within the well system bore  835 , at any step of the process or any time period. 
     The energy can be used to reduce or remove a reservoir&#39;s capacity to flow fluid by heating the reservoir and/or any injected fluid and solids artificially placed in and/or naturally occurring in said reservoir  860 . For example, drilling fluid or “mud” can have media in it that can form a wall cake  861  depending on the permeability and porosity of the formation in the well system. This wall cake  861  can be formed with materials that can be hardened and baked with the energy released by this invention&#39;s methods, thus forming a ceramic or impermeable well bore that restricts fluid flow. A wall cake  861  can be formed by using a catalyst  875  that reacts with a fluid, for example hydrogen peroxide, to cause energy to be released from the decomposition of the reactant. The energy can be used to cause materials, either natural or artificially placed in the reservoir, to reduce the permeability of the reservoir  860  and/or consolidate the reservoir. Furthermore, if the artificially placed media can be melted, like tin or lead, it can be used to form a consolidation or cementation effect on the reservoir once the material cools down after being melted by the exothermic heat release. Reducing a reservoir&#39;s  860  ability to conduct fluids to the bore  835  may be desirable to those skilled in the art. Reduced permeability can be used to seal off unwanted water encroachment, form barriers in the bottom of hydrocarbon barriers, seal of gas cap encroachment in a oil reservoir, or facilitate the placement of what is know as “frac pack” treatments. Similarly, a non-permeable and permanent hydraulic seal can be formed on the wall of the uncased portion of the well system bore  835  by applying energy from the reaction chamber  840 , and then fracturing the impermeable area with a sand laden fluid creating a fluid path to the reservoir  860  through the impermeable skin placed along the bore such that the sand in the hydraulically created fracture serves the purpose of filtering out sand and/or solids that may move with reservoir fluids as the well system is produced into the bore  835 . 
     The capability of the invention to control the down hole energy released within the well system by changing the mixture of at least one fluid and/or catalyst and/or moving the placement of the reaction chamber(s) allows for a plurality of fluids, solids, and/or solids suspended in fluids to be injected into the reservoir and heated with this inventions down hole energy release methods yielding varying degrees of consolidation as a function of their melting and sublimation temperatures. The solids or suspended solids may be injected from a supply tank  872 , through a pump  871  and into the bore  835  through a well system connection conduit  870  or any other means known in the art. 
       FIG. 8  illustrates one method of changing the ratio of a mixture of fluids ( 850 ,  851 ,  852 ) and/or a catalyst. A catalyst  875  is shown predisposed in the reaction chamber  840 , but is not so required, and may be injected. The ratio change, or mixing, can occur at a surface location or down hole. Although the injected mixture can include a catalyst, a fluid, for example hydrogen peroxide or other reactant fluid, can be injected through a conduit (not shown) disposed within the well system and into contact with a naturally occurring catalyst (not shown) without departing from the spirit of the invention. The invention does not require the step of artificially depositing the catalyst in the well system or reaction chamber  840 . For example, a well system may include naturally occurring oxides or metal impurities such as hematite and bauxite that may react with the fluid, for example hydrogen peroxide, to release energy. 
     A proportioning apparatus  853  can be connected to at least one pump  845  and tank ( 850 ,  851 ,  852 ). The proportioning apparatus  853  may include a valve or a pump and may be manually or electrically operated. Although three tanks ( 850 - 852 ) are shown, the invention is not so limited and can be a single tank or other type of fluid supply. The proportioning apparatus  853  may be directly connected to the pump  845  and/or reel  810  in fluid combination with the conduit  800 . The proportioning apparatus  853  can allow any mixture of fluid, solid, and/or catalyst to be provided for injection into the conduit  800  or well system bore  835 . The schematic details in the drawing and text of how the individual components are connected are for illustrative purposes only. Any mixing means can be used to create a mixture of fluids and/or catalyst and/or fuel for injection into the well system and/or reaction chamber  840 . The injection can occur through more than one conduit. The mixing step can occur in the reaction chamber  840 . 
     The mixture, and thus the energy released from the catalytic reaction, can be controlled from a surface location by changing the percentage of a first fluid, for example hydrogen peroxide, from a first tank  850  and a second fluid, for example water, from a second tank  851  through the proportioning apparatus  853 . The amount of energy released during the catalytic reaction can also be modified by adding different percentages of fuel, for example methanol, from a third tank  852  and/or catalyst at a surface location by blending them into the mixture to be injected through the conduit  800 . As discussed above, a solid or suspended solid or other media may be injected from a supply tank  872 , through a pump  871  and into the bore  835  through a well system connection conduit  870 . However, a solid, for example an abrasive solid, can also be added to the mixture via the proportioning apparatus  853  to give the energy exhausted down hole from an orifice  855  the ability to cut, jet, and/or drill the well system bore  835  or items in the well system. This may includes perforating the casing and/or formation with this energy and abrasive mixture. The abrasive can be sand or garnet, for example. Abrasive material may be added down a second conduit (not shown) and mixed at the exit port of a reaction chamber with the released energy that is selectively released. 
     Although the proportioning apparatus  853  is described in reference to  FIG. 8 , it can be used with any embodiment herein without departing from the spirit of the invention, for example with the catalyst used as a proppant. 
       FIG. 9  discloses another apparatus and method for selectively releasing energy in a well system. A first conduit  970  is shown disposed with the bore  935  of the well system and extending into the reservoir  960  from a tubing hanger  921  adjacent the well head devices  915 , which can for example include a blow out preventor or annular ram. The first conduit  970  has reaction chambers  940  which are shown absent a catalyst. Although no orifices are shown, they have formerly been present but now closed. A conduit  970 , which may have been previously used to release energy in a well system, may be used as a production conduit. 
     The second conduit  900  is shown attached to a reel  910  providing fluid communication with a pump  945  in fluid communication with a tank  950 , which can contain hydrogen peroxide, for example. The second conduit  900  is shown including optional unidirectional fluid check valves  933  and sealed to the well system with hydraulic seal  920 . 
     In use, the fluid, for example hydrogen peroxide, is injected past a unidirectional fluid check valve  933  and into contact with a catalyst  975  which may be present in a reaction chamber ( 941 ,  942 ). The fluid may then be used to power a turbine drill bit  999  on a distal end of the second conduit  900 . The fluid may react with the catalyst  975 , if present, to release energy. The “released energy” may be released from the first reaction chamber  941  out of an orifice  955  on the first reaction chamber  941 . The energy and/or fluid may be further injected into the second reaction chamber  942  where additional energy may be released from a second catalyst  975  and fluid reaction. The energy may be released from a reverse thrust jet  956 , as shown on the second reaction chamber  942 , to aid in the drilling by creating additional downward force. A portion or all of the energy may be released into the turbine drill bit  999  to provide power to drill the reservoir  960 . A portion of energy may be released from a downward facing jet  957  on a distal end of the conduit  900  to drill a formation, as is known to those skilled in the art. This method fluidizes the surrounding earth with the downward facing jet  957 . The conduit  900  can then become casing, and production can be achieved by cutting the conduit  900  at the surface, hanging it from a well head device  915 , and producing therethrough. The energy may further aid in the production of formation or well fluids from surface tubing  970  by adding energy to a fluid in the well system bore  935 . 
       FIG. 10  is another embodiment of a reaction chamber  1040 , shown threadably connected at a proximal end to a conduit  1000  which may be coiled tubing, for example. A catalyst  1075  is shown disposed in the bore of the reaction chamber  1040 . The distal end of the reaction chamber  1040  is shown threadably engaged to an optional sub  1010 . The sub  1010  contains a reverse thrust jet  1055 , but the sub may include any orifice or jet as desired, or no orifice or jet. The entire assembly may also be referred to as a reaction chamber. 
       FIG. 11  discloses another apparatus and method for selectively releasing energy in a well system. Multiple reaction chambers ( 1140 ,  1141 ) are shown with a catalyst  1175  disposed in each. A conduit  1100  is provided for injecting a reactant fluid into each reaction chamber ( 1140 ,  1141 ). Although not shown, each reaction chamber ( 1140 ,  1141 ) can have its own fluid supply conduit  1100 . The reaction chambers ( 1140 ,  1141 ) are disposed in side pocket mandrels of a second conduit  1170 . The second conduit  1170  is sealed to the bore  1135  of a well system by a packer  1102 . A fluid transducer  1199  is shown disposed in the bore of the second conduit  1170  with a turbine exhaust conduit  1171  extending into the well system bore  1135  and to a surface location. The fluid transducer  1199  may be a turbine pump or compressor which is powered by the first reaction chamber  1140  with the exhaust released from the exhaust conduit  1171  (shown) or into the bore of the second conduit  1170  to aid in lifting any fluid therein. 
     To use, a gas may be injected through the gas lift valve  1130  from the bore  1135  of the well system and into the bore of the second conduit  1170 . A reactant fluid may be pumped into either or both reaction chambers ( 1140 ,  1141 ) and into contact with the catalyst  1175 . The energy released from the catalytic reaction in the second reaction chamber can be selectively released into the bore of the second conduit  1170  to produce lift. If present, a turbine fluid transducer  1199  can be powered by selectively releasing the released energy from the first reaction chamber  1140  to power the turbine. The turbine can then pull a fluid through an intake port  1198  and up the bore of the second conduit  1170  to aid the lifting of any fluid in the bore, for example a hydrocarbon. A reaction chamber  1140  can be disposed into an existing side pocket mandrel of the second conduit  1170  from the surface as is known in the art. The reaction chamber  1140  can allow for connection with a first conduit  1100  extending to the surface during the disposition step. A reaction chamber may be removed when desired. This may include retrieving a reaction chamber  1140  from the bore of the second conduit  1170  by disposing a side pocket kick over into the side pocket mandrel, latching to a fishing neck (not shown) on the reaction chamber  1140 , jarring the reaction chamber  1140  from the side pocket mandrel, and removing the reaction chamber from the bore  1135  of the well system. 
     Although the reaction chamber is shown in each of the figures with a larger external diameter than the internal diameter of the conduit, the invention is not so limited. The reaction chamber can be sized so as to be removable from inside the conduit, for example from the surface with a fishing tool, without removing the conduit from a well system. A fishing tool may also be used to close an orifice on the conduit, for example to use the conduit as production tubing. Some orifices may be left open adjacent a reservoir to allow production therethrough. A reaction chamber may also be drilled out from a surface location by a drill bit disposed in the conduit. A reaction chamber can be used on any conduit, for example drill pipe. 
     Many other applications may be suggested which use the heat and/or energy associated with the chemical reaction described herein without departing from the spirit or intent of this disclosure. While the invention has been described with respect to a limited number of embodiments, those skilled in the art will appreciate numerous modifications and variations therefrom. It is intended that the appended claims cover all such modifications and variations as fall within the true spirit and scope of the invention.
