DETAILED DESCRIPTION OF THE INVENTION

(38) Referring now to FIG. 1, the self contain in-ground geothermal generator comprises a slim cylindrical shape, which, positioned vertically, can be lowered with a system of cables deep into the ground in a pre-drilled well. The self contained in-ground geothermal generator 100 of the invention is shown in cross sectional view, with main segments. The main elements of the assembly 100 are: the boiler 120, the turbine compartment 130, the gear box, or converter 140, the electric generator 150, the condenser/distributor 160, and system of cables and tubes 170 which includes electric cable for transporting electric energy up to the ground surface.

(39) Referring now to FIG. 2, enlarged cross sectional view of the self contain in-ground geothermal generator 100 shown in FIG. 1, taken along line 2-2 of FIG. 3. The main elements of the assembly 100 are: the boiler 120, the turbine compartment 130, the gear box, or converter 140, the electric generator 150, the condenser 160 with distributor chamber 61 and peripheral chamber 68 with system of tubes 62 for returning exhausted condensed steam as a feed water back into the boiler, and system of cables and tubes 170.

(40) The System of cables and tubes 170 includes peripheral caring cables 74, main caring cable 75, control cable 76, boiler supply tubes 121, cooling system tubes 72, and main electric cable 77, for transporting electric energy up to the ground surface.

(41) The boiler 120 includes lower part having a water tank area 122 and upper part having a steam area 124. The assembly 100 has a hook eye 71 and can be attached by hook 73 and cable 75 or with system of pulleys and cables and then lowered into pre-drilled well deep in the ground to the level where rocks heated by magma deep below the Earth's surface boils the water in the water tank area 122 of the lower part of the boiler 120. The steam in the steam area 124 of the upper part of the boiler 120 is also heated by surrounding hot rocks producing superheated steam. High-pressured superheated steam passes through a set of steam control valve 88 into a turbines compartment 130, which has a set of blades 32 which are attached to a solid shaft 34 and spins it. The solid shaft 34 of the turbines is connected to a cylindrical shaft 52 of the electric generator 150 through a gear box or converter 140. Steam from the turbine compartment is stirred through a set of openings 36 and through the cylindrical shaft 52 of the generator 150 into the distributor chamber 61 of the condenser 160. Exhausted steam then starts condensing and is stirred through the set of openings 63 into a plurality of tubes 62 and back into the feed water tank 110 and then pumped into boiler 120 through boiler feed pump 112 and boiler feed pipe 114.

(42) Here are also illustrated a structural external cylinder 90 and structural internal cylinder 80. The peripheral chamber 68 of the condenser 160 is formed in space between external cylinder 90 and internal cylinder 80. The peripheral chamber 68 has plurality of tubes 62 within, as explained above. There are structural ribs 85 between internal and external cylinders to improve structural integrity of the assembly in high pressure environment. The ribs 85 have holes 87 for water circulation. (For clarity and simplicity of the illustration the ribs 85 are not shown in FIGS. 1 and 2).

(43) The cooling system is an independent close loop tube which has at least two heat exchangers; first one down in the well and second one on the ground surface. First one which absorbs heat from condenser by circulating cool water through the peripheral chamber of the condenser, formed between external and internal cylinders, and then transfers the heat up on ground surface through thermally insulated closed loop pipes where heat is exchanged through second heat exchanger, which is a coiled pipe, and then cooled water returned to the condenser again.

(44) The cooling system consists of a close loop thermally insulated tube 72, one heat exchanger deep underground, which is peripheral chamber 68 of the condenser 160 and second one the coiled pipe 182 on the ground surface. (The coiled pipe 182 on the ground surface is shown in FIG. 12).

(45) The close loop tube 72 is attached to the peripheral chamber 68 of the condenser 160 through cooling water pumps 172 and 174. The cooling water pump 172 injects cooled water through pipe 178 to the bottom of the peripheral chamber 68. Water cools condenser by circulating through the peripheral chamber 68 of the condenser 160. The hot water, which naturally rises to the upper part of the peripheral chamber 68, is then injected through water pump 174 into other end of the tube 72 and taken up to the ground surface where heat is exchanged through coil tube 182, which is part of heat exchanger 184, and then returns cooled water to peripheral chamber 68 of the condenser 160. The heat on ground surface is then used to produce additional electricity in a binary power plant through system of several heat exchangers (Explained in FIG. 12-19).

(46) The peripheral chamber 68, which is part of the condenser 160, is strategically positioned so that besides cooling condenser 160, also surrounds, cools and prevent from overheating turbines 130, gear box/converter 140, and electromagnetic generator 150.

(47) The close loop tube 72 have at least one water pump 172 in line (preferably several) to provide water circulation through the thermally insulated tube line and to reduce hydrostatic pressure at the lower part of the close loop system. If necessary several close loop tube 72 can be installed on unite to speed up cooling and heat exchange process. The ratio of speed and pressure inside closed loop line are constant. P (pressure)V (speed)=constant. More speed=less pressure.

(48) As an alternative solution; the peripheral chamber 68 of the condenser 160 can be supplied and cooled with an additional independent coiled metal pipe (heat exchanger) and close loop system similar to one shown in FIG. 13.

(49) The peripheral wall of the boiler 120 can have indentations to increase conductive surface and to increase conductivity of heat to the water inside boiler (For simplicity not shown).

(50) The boiler 120 is filled with water, after whole assembly of the self contained in-ground geothermal generator 100 is lowered to the bottom of the well, through set of tubes 121, to reduce weight of assembly during lowering process. Illustrated are two tubes 121 attached to the unitone to supply water into boiler 120 and other to let air escape during filling process. Also important purpose of the tubes 121 is to supply, maintain and regulate necessary level of water in boiler 120.

(51) All main elements of the assembly 100; the boiler 120, the turbine compartment 130, the gear box, or converter 140, the electric generator 150, and the condenser/distributor 160, can be assembled during lowering process by fusing multi sections of same kind to the desired length and capacity. The fusing process can be bolting or welding.

(52) There is a set of protruded holding pins 66 on each assembly segment so it can be carried with set of separate peripheral cables 74 to reduce tension on main cable 75 during lowering or lifting the assembly.

(53) The condenser 68, which is formed between structural external 90 and structural internal 80 cylinders, which surrounds and cools whole unit, except boiler 120, is insulated from external heat of hot rocks with tick layer of heat resistant insulation 92.

(54) The boiler 120 has a safety check valve 126 to release steam, if needed, in emergency such as if control valves malfunction, etc.

(55) The purpose of the gear box or converter 140, which is located between turbines 130 and the electric generator 150, is to neutralize momentum produced by the spinning turbines 33 by changing the direction of the rotor 54 of the generator 150. Thus the rotor 54 of the generator 150 spins in the opposite direction than the main turbines 33. If needed, several gear boxes or converters 140 can be installed into generator compartment to neutralize or balance momentum produced by the spinning turbines and generators.

(56) Referring now to FIG. 5-8, the upper end of turbines shaft 34 is solidly connected with disk/platform 35 which extend to the peripheral cylinder 41 of the gear box 140, with which is secured and engage with system of bearings 42 and gears wheels 43. Gear box is secured to the main structural cylinder 80. Disk/platform 35 has several openings 36 for steam to leave turbines compartment. Disk/platform 35 also extends upwardly in shape of funnel 39 for steam to be funneled into cylindrical shaft 52 of the electric generator 150. The cylindrical shaft 52 of the rotor 54 also functions as a secondary turbine. It has secondary set of small blades 58 attached to the inside wall and positioned so to increase rotation of the rotor when steam passes through.

(57) Disk/platform 35 is engage with upper disc/platform 37 through set of gear wheels 43, which are secured with peripheral cylinder 41 of the gear box 140 with their axles/pins 44. The upper disk/platform 37 is also engage with upper part 38 of the funnel 39 through bearing 46 and with peripheral cylinder 41 of the gear box 140 through bearing 47 and is also solidly connected to cylindrical shaft 52 of the generator 150.

(68) FIG. 12 is a schematic diagram of cross sectional view of the self contained in-ground geothermal generator, with main segments including heat exchanger on the ground surface. The self contained in-ground geothermal generator (SCI-GGG) uses three closed loop systems. The first closed loop system circulates working fluid through boiler, turbine, generator, condenser and back through boiler. The second closed loop system (self contained heat exchanger) circulates fluid through condenser, thermally insulated pipes and coil coupled to binary power unit on the ground surface. The self contained heat exchanger (SCHE) is integral part of the SCI-GGG apparatus and can be used separately as an independent heat exchanger. The third closed loop system circulates working fluid through binary power unit on the ground surface and produces additional electricity. FIG. 12 illustrates the boiler 120, the turbines 130, the gear box 140, the electric generator 150, and the condenser 160. Here is also shown peripheral chamber 68 of the condenser 160 which function as a heat exchanger by cooling tubes 62 which are spread within. (For simplicity and clarity tubes 62 are not shown here). Here is also shown coil tube 182 which exchanges heat in a heat exchanger 184 up on the ground surface, which is part of the binary geothermal power plant 180, which is explained in FIG. 14. The peripheral chamber 68 of the condenser 160, which function as a heat exchanger down in the unite and coiled pipe 182, which exchanges heat in a heat exchanger 184 up on the ground surface are connected with close loop tubes 72 which are thermally insolated to prevent lousing heat during fluid transport between heat exchangers. Here are also illustrated several water pumps 172 and 174 which circulate water through close loop system. An alternative in-line pump is later explained and illustrated in FIGS. 22 and 23. Also here is shown cable connector platform 176 which connects segments of tubes and cables. Also here is shown main cable 75, and insulation layer 92.

(69) FIG. 13 is a schematic diagram of cross sectional view of an alternative, independent, self contained heat exchange system. The self contained heat exchanger (SCHE) apparatus is integral part of the self contained in-ground geothermal generator (SCI-GGG) apparatus (illustrated in FIG. 12) and is used separately as an independent heat exchanger. Here in FIG. 13 is illustrated the self contained heat exchanger (SCHE) apparatus with two closed loop systems. The main segments of first closed loop system include; a close loop tube, first heat exchanger 168 deep in the ground at heat source and second heat exchanger 182 up on the ground surface which is part of the second closed loop system which is binary power unit 184. The second closed loop system circulates working fluid through binary power unit on the ground surface and produces additional electricity. The main segments of second closed loop system include; a boiler, a turbine, a generator and condenser (illustrated in FIG. 14). Here in FIG. 13 are illustrated the same elements of the cooling system shown in FIG. 12, namely; one heat exchanger deep in the ground at heat source and one up on the ground surface and one close loop thermally insulated tube with several in-line water pumps which circulates water through close loop system.

(70) In this embodiment, instead of peripheral chamber 68 which functions as a heat exchanger, a coiled pipe 188 is used which functions as a first heat exchanger 168. The heat exchanger 168 consists of; the strait pipe 189, the coiled pipe 188, the structural pipe 187 and the platform 186. The structural pipe 187 which provide strength to the unit is attached to the platform 186. The structural pipe 187 has one opening at the bottom for strait pipe 189 to exit and one opening at top for strait tube 189 to enter. The structural pipe 187, which prevent coiled pipe 188 from collapsing from its weight, may have more perforations if necessary to reduce its weight and to provide more heat to the strait pipe 189. The spacers which keep distances between coils in coiled pipe 188 and structural pipe 187 are not illustrated. Here is also shown base 185 of structural pipe 187 on which whole assembly rest. Alternatively, structural pipe 187 can be adapted to perform the function of the strait pipe 189.

(71) The coiled pipe 188 which functions as first heat exchanger 168 down in the ground and coiled pipe 182 which functions as second heat exchanger 184 up on the ground surface are connected with close loop tube 72. Here are also illustrated several in-line water pumps 172 and 174 which circulate water through close loop system. The heat from hot rocks deep in the well is absorbed through first heat exchanger 168 and transported with thermally insulated pipe 72 up to the ground surface to the second heat exchanger 184 where its heat is transferred into a binary power unit which uses working fluids, such as isopentane, that boils at a lower temperature than water. The heat exchanger 184 is part of the binary geothermal power plant 180, which is explained in FIG. 14.

(72) Also here is shown cable connector platform 176 which connects segments of tubes 72 and cable 75. Connector platform 176 or a plurality of platforms 176 may also function as a barrier(s) or a plug(s) to reduce the amount of heat escaping from the well bore.

(73) The heat exchange system explained here in FIG. 13. is an alternative cooling system for a self-contained in-ground geothermal generator can also function as an alternative, independent, heat exchange system, which would be substantial improvement to experimental process so called hot dry rock technology.

(74) The simplest hot dry rock technology power plant comprises one injection well and two production wells. Scientist are trying to drill down injection well into the rocks and then inject down into well, under pressure, what ever water source they have happen to have on the surface hoping that water will travel through cracks and fissures of the hot rocks and form underground reservoir, and then they intend to drill production wells around perimeter and try to recover that water and steam by pumping it back to surface and then use it in a conventional or in a binary power plant.

(75) Binary plants use lower-temperature, but much more common, hot water resources (100 F.-300 F.). The hot water is passed through a heat exchanger in conjunction with a secondary (hence, binary plant) fluid with a lower boiling point (usually a hydrocarbon such as isobutane or isopentane). The secondary fluid vaporizes, which turns the turbines, which drive the generators. The remaining secondary fluid is simply recycled through the heat exchanger. The geothermal fluid is condensed and returned to the reservoir.

(76) It remains to be seen if presently experimental hot dry rock technology can function as expected and answer special challenges: 1. It requires a huge amount of water to form, deep down, man made, hydrothermal reservoir in a place where water has not been naturally accumulated. 2. Would a huge amount of water be lost, absorbed into rocks in different directions? 3. How much of water, if any, could reach production well through cracks and fissures in the hot rocks? 4. How mach water, if any can be recovered and pumped back on ground surface to be used in a conventional or in a binary power plant? 5. Also, during pumping up water to the surface through production well water will pass through layers of gradually less hot rocks and eventually through cold rocks close to the surfacehow much of the heat will be lost and how much of water will be lostabsorbed into rocks during trip up? 6. There is strong indications that experimental Enhanced Geothermal System (EGS) can induce seismicity because injected water can find underground pockets (caves) and with high pressure and temperature can induce explosion.

(77) The heat exchange system explained here in FIG. 13 is a simple system which uses the same amount of water all the time because it is literally close loop system, not just binary part on the ground surface but also part down in the ground. It doesn't deal with removing silica and minerals in a separator from the geothermal fluid.

(78) It doesn't lose water into cracks and fissures of the hot rocks because water circulates through coiled pipe and houses. The lost of heat on the trip up is limited because pipes are thermally insolated. It doesn't require several wells to function (injection well and several production wells) it rather uses single well for each unit. The heat exchange system explained herein in FIG. 13 as well the apparatus explained in FIG. 12 can operate, not just in dry hot rocks areas but also, in areas with hydrothermal reservoirs and many other applications including cooling dysfunctional nuclear reactors or in reverse process warming surroundings if needed.

(79) FIG. 14 is a schematic diagram of cross sectional view of the binary geothermal power plant 180. Here are illustrated; the heat exchanger 184, the turbines 230, the condenser 260 and electric generator 250. Hot water from deep underground passes through close loop tube 72 into coil 182 inside heat exchanger 184 where its heat is transferred into a second (binary) liquid, such as isopentane, that boils at a lower temperature than water. When heated, the binary liquid flashes to vapor, which, like steam, expands across, passes through steam pipe 222 and control valve 288 and then spins the turbine 230. Exhausted vapor is then condensed to a liquid in the condenser 260 and then is pumped back into boiler 220 through feed pipe 214 and boiler feed pump 212. In this closed loop cycle, vapor is reused repeatedly and there are no emissions to the air. The shaft of the turbines 230 is connected with shaft of the electric generator 250 which spins and produces electricity, which is then transported through electric cable 277 to transformer and grid line to the users. (Transformer and grid line are not illustrated). The binary power unit 180 can be produced as portable unit on wheels (on chase of truck 18 wheeler). The condenser 260 is elongated to reduce back pressure which exists after steam passes through turbine compartment 230. The length of the condenser 260 can be increased if needed.

(80) FIG. 15 is a schematic diagram of cross sectional view of a geothermal power plant 190 (not a binary power plant), as an alternative solution for cases where water coming from tube 72 is hot enough to produce steam. (It may be applicable in an alternative, independent, heat exchange system shown in FIG. 13). Here are illustrated; the boiler 220, the turbines 230, the condenser 260 and electric generator 250. Hot water from deep underground passes through close loop tube 72 into boiler 220 where evaporates. The steam then passes through steam pipe 222 and control valve 288 and then spins the turbine 230. Exhausted vapor is then condensed to a liquid in the condenser 260, which can be air or water cooled, and then is pumped back into close loop tube 72 which leads into well as explain earlier. Here is also shown feed pipe 214 and water pump 212 which are part of close loop system. Here is also shown shaft of the turbines 230 which is connected with shaft of the electric generator 250 which spins and produces electricity. Electricity is then transported through electric cable 277 to transformer and grid line to the users. (Transformer and grid line are not illustrated).

(81) FIGS. 16 and 17 illustrate plain view of the geothermal power plant 300 with 24 wells and control center 200 in accordance with the invention. For clarity and simplicity, here is shown schematic diagram only of one quarter of the plant, 6 wells 19-24, and three binary power units 132, 142 and 152. The other three quarters of the power plant are identical.

(82) As explained earlier the cooling system of the self contained in-ground geothermal generator 100, is a close loop tube system which cools condenser by circulating water through the peripheral chamber 68 of the condenser 160, formed between external and internal cylinders 90 and 80, and then transfers the heat up on ground surface. The heat on the ground surface is then used to produce additional electricity in a binary power plant through system of several heat exchangers and then returned as cooled water to the relevant peripheral chamber 68 of the condenser 160.

(83) Here are illustrated three binary power units 132, 142 and 152 which are connected with six self contained in-ground geothermal generators inside wells 19-24.

(84) Each of those three binary power units 132, 142 and 152 consist of: the boilers 133, 143 and 153, the turbines 134, 144 and 154 and the electric generators 135, 145 and 155.

(85) The boiler 133 of the binary production unit 132 has six heat exchange coils 319, 320, 321, 322, 323 and 324, which are connected to the condensers 160 of the relevant self contained in-ground geothermal generators, inside wells 19, 20, 21, 22, 23 and 24 with one end of the tube of close loop system.

(86) Before other end of the tube of close loop system reaches the condensers 160 of the relevant self contained in-ground geothermal generators inside wells 19, 20, 21, 22, 23 and 24 and complete close loop cycle, it also passes through boilers 143 and 153 of the binary production units 142 and 152. The purpose of it is to exchange heat and use it on the ground surface in the binary production units as much as possible and to send back cooled water to the condensers 160. For clarity and simplicity, any radiant tubing is not shown and directions of the flow through line are marked with arrow sign.

(87) The boiler 143 of the binary production unit 142 has also six heat exchange coils 419, 420, 421, 422, 423 and 424.

(88) The boiler 153 of the binary production unit 152 has also six heat exchange coils 519, 520, 521, 522, 523 and 524.

(89) The boiler 133 of the binary production unit 132 produces the hottest steam because it is the first station where heat is exchanged through coils 319, 320, 321, 322, 323 and 324.

(90) The boiler 143 of the binary production unit 142 is the second station where heat is exchanged through coils 419, 420, 421, 422, 423 and 424, and steam temperature is lesser than in boiler 133.

(91) The boiler 153 of the binary production unit 152 is the third station where heat is exchanged through coils 519, 520, 521, 522, 523 and 524, and steam temperature is lesser than in boiler 143.

(92) The binary power units 132, 142 and 152 are designed to operate at different steam temperature and presser.

(93) As an alternative solution; the steam from boilers 133, 143 and 153, which deal with different temperature and pressure, can be funneled to a single binary power unit with single turbine and generator.

(94) As an alternative solution; after leaving coils 519, 520, 521, 522, 523 and 524 of the binary production unit 152, if water is still hot, the tube 72 can be cooled with running water, if available, or can be used for heating building.

(95) FIG. 17 is enlarged schematic diagram of the one section of the geothermal power plant 300 shown in FIG. 16.

(96) FIG. 18 is enlarged plain view of the boiler 133 of the binary production unit 132 illustrated in FIGS. 16 and 17. Here are shown heat exchange coils 319, 320, 321, 322, 323, 324 and main steam pipe 222.

(97) FIG. 19 is an enlarged cross sectional view of the boiler 133 of the binary production unit 132 taken along line 19-19 of FIG. 18. Here are also shown heat exchange coils 322, 323, and 324 from which its heat is transferred into a second (binary) liquid, such as isopentane, that boils at a lower temperature than water. When heated, the binary liquid flashes to vapor, which, like steam, expands across, passes through steam pipe 222. (The process is explained in binary power plant earlier in FIG. 14). Here is also shown feed pipe 214 through which exhausted vapor are returned into boiler 133 for reheating.

(98) FIG. 20 illustrate a cross sectional view of an alternative tower 240 for assembling, lowering or lifting the self contained in-ground geothermal generator 100. Here are shown structural frame 249 of the tower 240. Also shown here are well 19, lining of the well 247, foundation platform 248, and system of ratchets 242 and 246 for main cable 75 and peripheral cables 74. (Cables are not shown).

(99) FIG. 21 illustrate a cross sectional view of an alternative tower 241 for assembling, lowering or lifting the self contained in-ground geothermal generator 100, with wind mill 245 installed on it, as an additional source of energy if geothermal power plant is located in windy area. The tower 241 is similar as tower 240 illustrated in FIG. 20 with addition of extension element 235. Here are also shown structural frame 249, well 19, lining of the well 247, foundation platform 248, and system of ratchets 242 and 246 for main cable 75 and peripheral cables 74. (Cables are not shown). Also illustrated here are conventional generator with gear box 244 and blades 243. The objective of this addition is to use assembling tower also as a platform for wind mill. It will be understood that the tower 241 may be permanent or temporary.

(100) FIGS. 22 and 23 show an in-line pump 172 which is part of the heat exchange systems of the apparatuses illustrated in FIGS. 12 and 13. The in-line pump 172 also illustrated (numbered) as 174 is a replaceable segment in closed loop line 72 of the heat exchange system of the apparatuses illustrated in FIGS. 12 and 13. In-line pump 172 is an electric motor 91 consisting of a rotor 102 and a stator 104. The rotor 102 consists of a hollow shaft 50 which is fixedly surrounded with an electromagnetic coil 93. The stator 104 consists of a cylinder 105 which is housing of the motor 91 and is fixedly engaged with electromagnetic coil 95. Stator 104 and rotor 102 are engaged through two sets of ball bearings 97 and additional set of sealant bearings 98. The cylinder 105 of the motor 91 has diameter reduction on each end and is coupled with the connector platform 176 which connects segments of the closed loop line 72. The hollow shaft 50 has continuous spiral blades 51 formed on the inner side of the hollow shaft 50. When electro motor 91 is activated the hollow shaft 50 which is central element of the rotor 102 rotates with the continuous spiral blade 51 which is coupled within the hollow central shaft 50 of the rotor 102 creating a force to move fluid through the closed loop line 72. The spiral blade(s) 51 can also be fixed within the hollow central shaft 50. The shape of the inline pump 172 is cylindrical and slim, thus suitable to fit in limited spaces such as well bore. The slim cylindrical shape of the inline pump 172 has no limitation on length therefore power of the electromotor can be increased to provided substantial pumping force as needed for fluid to circulate at certain speed.

(101) The in-line pump 172 can be used in many applications wherever substantial pumping force is needed. For example with minor additions (not shown) like forming extra space by adding an additional peripheral cylinder filled with oil to provide buoyancy to this in-line pump 172 can be used in deep water drilling as a segment of raiser pipe. Further, the closed loop line 72 may be, but is not limited to, a closed loop system line. Alternatively, the in-line pump 172 can be used for pumping up fluid from a reservoir in which underground pressure is low (geo-pressure). For example the in-line pump 172 can be used for pumping up oil from oil wells (reservoirs) in which underground pressure (geo-pressure) is low, or any other type of fluid from a reservoir, such as, but not limited to, water or natural gas. The in-line pump 172 can be inserted as a repetitive segment of the raiser pipe through which oil is pumped up to the ground surface. The in-line pump can be programmed or equipped with sensors so the pump can be activated when submerged or filled with fluid. The hollow shaft 50 with continuous spiral blades 51 formed on the inner side of the hollow shaft can be produced by aligning and welding pre-machined two halves. Alternatively, the shaft can be produced by aligning and welding prefabricated several segments of spiral blade with section of the wall of the hollow shaft (cylinder).

(102) The in-line pump 172 is an electromotor cylindrical shape and can be inserted as a repetitive segment in line and has no limitation on length therefore the power of the electromotor can be increased to impart needed pumping force for fluid to circulate at desired speed. For example the in-line pump 172 can be used in cross country pipe line for oil, gas, water, etc. as a repetitive segment. In downhill route it can function as a generator and produce electricity which can be used to supplement power to the electromotor In-Line Pump in horizontal and uphill route.

(103) FIG. 24 illustrate an alternative schematic cross sectional diagram of an universal heat exchange system 210 shown in FIG. 13, with main segments including a thermally insulated close loop line 72 with an in-line pump 172, first heat exchanger 168 positioned in heat source environment A and the second heat exchanger 182 positioned in preferred environment B. By circulating heat exchanging fluid through closed loop system heat is extracted from heat source through the first heat exchanger 168 and transferred through thermally insulated line 72 to the second heat exchanger 182 for external use including production of electricity. The heat exchange system 210 is portable and can be used in many applications. This illustration is only a schematic diagram of the heat exchange system so details such as fluid expansion reservoir and safety valves are not illustrated.

(104) FIG. 25 illustrates a schematic plain view diagram of the heat exchange system 210 shown in FIG. 24 to be used in dysfunctional nuclear power complex, such as, but not limited to Fukushima Daiichi Nuclear Power Complex, to improve issues with heat transfer and Ocean contamination. It has been reported these days that dysfunctional nuclear reactor is cooled by pouring salty water over it and then collecting that radioactive water into reservoirs and repeating the process. Leakage of radioactive water has been detected on the ground and in the Ocean. Here in FIG. 25 is illustrated dysfunctional nuclear reactor 163, Ocean 165 and closed loop heat exchanger system 210. The first heat exchanger 168 is lowered into dysfunctional nuclear reactor 163 and the second heat exchanger 182 is lowered into nearby Ocean 165. By circulating heat exchanging fluid through closed loop system 210 heat is extracted from dysfunctional nuclear reactor 163 and transferred through the first heat exchanger 168 and through thermally insulated line 72, which is formed from repetitive segments, to the second heat exchanger 182 and dispersed safely into the Ocean 165. Multiple units of the closed loop system 210 can be deployed with additional insulations if needed. Heat exchange fluid in closed loop system 210 is not in direct contact with radioactive material in dysfunctional nuclear reactor 163 or the Ocean 165. Although here in FIG. 25 is shown method how to extract heat from dysfunctional reactor(s) and disperse it safely into the Ocean, as a first task to improve desperate emergency situation, if needed, additional elements such as mobile power units can be implemented nearby to produce needed electricity in the process as shown in FIG. 26 and others illustrations of this invention.

(105) FIG. 26 illustrates a schematic diagram of the heat exchange system 210 shown in FIG. 24 to be used for production of electricity in location where lava is accessible, such as, but not limited to Hawaii. Here in FIG. 26 are illustrated two posts/towers 192 and 194 erected on either side of a lava flow/tube 196 with cable 193 suspended between them. The first heat exchanger 168 is lowered at safe distance closed to lava flow 196 and the second heat exchanger 182 is coupled into boiler/evaporator 220 of the binary power unit 180 which is explained in FIGS. 14 and 15. Here are also illustrated turbines 230, generator 250 and condenser 260. Here is also illustrated cooling system for the condenser 260 consisting of additional closed loop system 270 which consist of several interconnected back pressure reducing cylinders 262, with coiled heat exchangers 268 inside, thermally insulating lines 272 and heat exchanger 282 submerged into Ocean 165. There is also an in-line pump 172 to circulate heat exchanging fluid through closed loop system 270. The condenser 260 is elongated with back pressure reducing cylinders 262 to reduce back pressure which exists after steam passes through turbine compartment 230. By implementing this methodology, for example, the State Hawaii could save around one billion dollars which they are spending yearly for purchase of oil for production of electricity.

(106) FIG. 27 illustrate a schematic cross sectional diagram of the heat exchange system 210 shown in FIG. 24 to be used for production of electricity from heat source such as oil well flare stacks. A gas flare, alternatively known as a flare stack, is a gas combustion device used in industrial plants such as petroleum refineries, chemical plants, natural gas processing plants as well as at oil or gas production sites having oil wells, gas wells, offshore oil and gas rigs and landfills. Whenever industrial plant equipment items are over-pressured, the pressure relief valve provided as essential safety device on the equipment automatically release gases which are ignited and burned. Here in FIG. 27 are illustrated oil well flare stack 137, support structure 138, the heat exchange system 210 with first heat exchanger 168 positioned on top of supporting structure 138 and second heat exchanger 182 coupled into boiler/evaporator 220 of the binary power unit 180. By circulating heat exchanging fluid through closed loop system 210 heat from flame 139 is extracted through the first heat exchanger 168 and transferred through thermally insulated line 72 to the second heat exchanger 182 which heats working fluid or water, depending on size and temperature, in the boiler/evaporator 220 of the binary power unit 180. Here are also illustrated main elements of the binary power unit 180, turbines 230, generator 250 and condenser 260. In this illustration the condenser 260 is cooled with additional closed loop system 270 consisting of the first heat exchanger 268, closed loop line 272 and the second heat exchanger 282 which can be submerged into nearby source of cold water 166 such as pool, lake, river, etc. By implementing this methodology worldwide in industrial plants a lot of electricity can be produced from sources considered at this time as a waste.

(107) FIG. 28 illustrates a schematic cross sectional diagram of an alternative heat exchange system to one shown and explained in FIG. 27. The assembly illustrated in FIG. 28 is essentially the same as assembly illustrated in FIG. 27; only difference is that instead of boiler 220 in FIG. 27 there is heat exchanger unit 221 which contains two heat exchangers 182 and 183. The heat exchanger unit 221 is filled with heat exchange medium fluid. There is also relief valve 224 and valve 225 for controlling the heat exchange medium fluid.

(108) FIG. 29 illustrates a plain view of the geothermal facility using the heat exchange system 210 shown in FIG. 24 for production of electricity and desalinization of water from a salty body of water. By way of example only, a salty body of water may include the Salton Sea in California. The following example using the Salton Sea as the salty body of water is for illustration purposes and it is understood that this invention is not limited to only functioning with regard to the Salton Sea, but rather the same principles are applicable to any salty body of water. The Salton Sea is California's largest lake and is presently 25 percent saltier than the ocean. The Salton Sea is a terminal lake, meaning that it has no outlets. Water flows into it from several limited sources but the only way water leaves the sea is by evaporation. The Salton Sea Geothermal Field (SSGF) is a high salinity and high-temperature resource. The earth crust at south end of the Salton Sea is relatively thin. Temperatures in the Salton Sea Geothermal Field can reach 680 degrees less than a mile below the surface. There are already several conventional geothermal power plants in the area. The lake is shrinking exposing lake bed and salinity level is increasing which is pending environmental disaster and a serious threat to multi-billion-dollar tourism.

(109) In this application the heat exchange system 210 extracts heat from geothermal sources; transfers that heat up to the ground surface; produces electricity for commercial use; and at same time, desalinize salty water and returns produced freshwater into Salton Sea; and in process produces salt which has commercial value.

(110) Here is illustrated the heat exchange system 210 with first heat exchanger 168 lowered into well-bore 30 at source of heat (see FIG. 30), thermally insulated line 72, and second heat exchanger 182 coupled into boiler/evaporator 217 of the power unit 280. By circulating heat exchanging fluid through closed loop system 210 heat from hot rocks or hydrothermal reservoir is extracted through the first heat exchanger 168 and transferred through thermally insulated line 72 to the second heat exchanger 182 which is coupled into boiler/evaporator/distiller 217 of the power unit 280. Salty water from Salton Sea is injected into boiler/evaporator 217 through pipe line 264 and valve 267 to the level H (see FIGS. 30 and 31). The second heat exchanger 182 which is coupled into boiler/evaporator 217 heats salty water and steam is produced which turns turbine 230 which is connected to and spins generator 250 which produces electricity which is then transmitted though electric grid. The power unit 280 has the condenser 260 which is cooled with additional closed loop system 270 consisting of the first heat exchanger 268, closed loop line 272 and the second heat exchanger 282 which is submerged into Salton Sea for cooling or if necessary nearby pool build for that purpose. Condensed steam from condenser 260 exits power plant 280 through pipe 256 to join pipe line 266 returning fresh water into Salton Sea. Alternatively, fresh water can be collected into big thanks (not illustrated) for use when needed in nearby agricultural fields. The pipe line 272 exiting condenser 260 enters heat exchanger containers 254 which are positioned underneath removable pans 252 located in nearby desalinization processing building 290 (see FIG. 31) which is closed and incites a greenhouse effect.

(111) Alternatively, if situation regarding desalinization of the Salton Sea changes, the boiler/evaporator 217 and cooling system of the condenser 260 of the power unit 280 can be modified to function solely as binary power unit to produce only electricity.

(112) The pipe line 72 after exiting boiler/evaporator 217 branches into pipe line 78 which also enters the heat exchanger containers 254 which are positioned underneath removable pans 252 located in nearby desalinization processing building 290 (see FIG. 31).

(113) When salty water in boiler 217 reaches level L the salinity level is high and is released through valve 269 and pipe line 265 into collector pools 263 at nearby desalinization processing building 290 in which salt and clean water is produced.

(114) Salty water from collector pools 263 is distributed into removable pans 252 which sit on the heat exchanger containers 254 which are filled with heat exchange fluid and accommodates three pipe lines, 78, 272 and 108 which heats heat exchange fluid in containers 254 and indirectly heats salty water in pans 252. Salty water evaporates from heated pans 252 and condenses around condensers panels 289 which are positioned under roof structure 292 of the desalinization processing building 290. The pipe line 278 after branching from pipe line 272 enters roof section 292 of the desalinization processing building 290 and function as a condenser. Condensed fresh water 293 drops, as a rain, into channels 294 from which is then collected into containers 271 and returned into Salton Sea through pipe line 266 (see FIGS. 31 and 32). After heated water evaporates from pans 252 layer of salt will form on the bottom of the pans 252. The pans 252 with salt in it can be raised with cable and ratchets or hydraulic system so that one end of the pans 252 is higher than other (illustrated with dash line in FIG. 31) and then slightly jerked and unloaded salt on vehicle or platform for transport. The profile of the removable pan 252 on lower end is slightly larger for smoother unload and can have closing and opening mechanism (not shown at this illustration). Here is also illustrated a well 30 with Blow Out Preventer 31 and derrick 240 above it.

(115) Here are also illustrated two sections of the desalinization processing building 290. The building can have many such sections to allow continues process of loading and unloading in harmony.

(116) FIG. 30 is a cross sectional view taken along line 30-30 of FIG. 29. Beside already explained elements and its functions in FIG. 29 here are better illustrated well-bore 30 with casing 247 and the first heat exchanger 168 in it, and rest of elements of the power plant 280. Here is also illustrated, as an alternative option, at the bottom of the well-bore 30, an in-line pump 172 which can be attached, if needed, to the first heat exchanger 168 to circulate geothermal fluids upward and around first heat exchanger 168 for more efficient heat exchange. Here is illustrated an in-line pump 172 having two fluid stirring elements 173 on each end. The fluid stirring elements 173 are simple structural pipe sections with openings on side wall preferably in an angel (not illustrated). The purpose of the fluid stirring elements 173 on the lower end of the in-line pump 172 is to direct surrounding geothermal fluid into in-line pump 172 and purpose of the fluid stirring elements 173 on the upper end of the in-line pump 172 is to direct geothermal fluid from the in-line pump up and around first heat exchanger 168. Here is also illustrated base of structural pipe 185.

(117) FIG. 31 is a cross sectional view taken along line 31-31 of FIG. 29. In this illustration are shown removable pans 252 which sits on the heat exchanger containers 254 which are filled with heat exchange fluid and accommodates three pipe lines, 78, 272 and 108 which heats heat exchange fluid in containers 254 and indirectly heats salty water in pans 252. Here is also shown thermal insulator and supporting structure 255 under containers 254.

(118) In this illustration, there are also shown roof structures 292 of the closed desalinization processing building 290 with pipe lines 278 which supply cold water to the condenser panels 279. Condenser panels are illustrated in two alternative positions on left and right side of the building 290. Here are also shown collecting pans 284 positioned underneath condenser panels 279 (illustrated in FIG. 32). Here are also illustrated plastic curtains 276 with vertical tubes 296, which collect and funnel condensed droplets 293 into provided channels 294. The plastic curtains 276 are preferably inflatable to provide thermal insulation between warm lower section and cold upper section of the building 290. If necessary upper section can be additionally cooled with air-condition system. Here is also shown raised removable pans 252 (in dash line). Here are also shown thermo-solar panel 106 on the roof of the desalinization processing building 290 and corresponding heat exchange line 108 inside the heat exchanger containers 254 which is illustrated and explained in FIG. 32.

(119) FIG. 32 illustrates a perspective cross sectional diagram of an alternative thermo-solar heat exchange system 70 to be used in desalinization plant shown in FIGS. 29-31. Here is illustrated, an optional solution, thermo-solar panel 106 positioned on the roof of the desalinization processing building 290 to be used for heating heat exchange fluid in the containers 254 and indirectly heating salty water in pans 252 to induce evaporation. Here is also illustrated a plate 283 at the bottom of condenser 279 which function as a frame for the condenser 279 and also as an electrode positively (+) charged. The condenser 279 is coated with super hydrophobic material to induce release of tiny water droplets from condenser and subsequently to improve condensation process. Here is also illustrated a pan 284 positioned underneath condenser 279. The pan 284 has Y shape profile and collects condensed droplets 293 from the condenser 279 and delivers fresh water 295 into containers 271 (shown in FIG. 29). The fresh water 295 is then pumped into sea. The pan 284 is negatively charged to improve condensation process.

(120) Recent study done by MIT researchers have discovered that tiny water droplets that form on a superhydrophobic surface and then jump away from that surface, carry positive (+) electric charge. By adding negative () charges to nearby surface can prevent returning of the tiny water droplets back to the condenser surface and improve condensation process.

(121) Alternatively, if needed, thermo-solar panel 106 positioned on the roof of the desalinization processing building 290 used for heating heat exchange fluid in the containers 254 and indirectly heating salty water in pans 252 to induce evaporation, could function independently without geothermal support.

(122) FIGS. 33-36 illustrate a cross sectional views of the load carrying system 60 and the cable and tube connector assembly 175 also illustrated in FIG. 13. By lowering the SCI-GGG and/or SCI-GHE apparatus by adding repetitive segments of tubes and cables, the length of the apparatus increases and subsequently its weight. Therefore load carrying structure such as cables or pipe, in these illustrations cables, is designed so that additional cables can be added to accommodate increased weight when additional segments of the apparatus are added. The length of segments of the apparatus depends of the size of derrick.

(123) FIG. 33 is a schematic diagram of cross sectional view of the load carrying cable system 60. The load carrying system 60 consist of derrick with pulley system on the surface (not shown in this illustration), repetitive cable segments 75 which are connected through the cable and tube connector platforms 176. Here are also illustrated transferring cables 83 which are inserted as periodic segments when load from one cable needs to be transferred on two cables of the subsequent segment. The transferring cables 83 consist of a sling cable 89, an oblong master link 99, which connects two legs 81 ending with standard latched sling hooks 55 (not shown in this illustration). This load carrying system 60 provides overall weight reduction and efficient load distribution of the apparatus and subsequently extends the operating depth of the apparatus and increases load capacity of the derrick.

(124) FIG. 34 illustrate a cross sectional views of the cable and tube connector assembly 175 taken along line 34-34 of FIG. 35. The cable and tube connector assembly 175 consist of the cable and tube connector platform 176, on which are permanently fastened two hose and socket assembly 177 (illustrated on FIG. 35) and multiple steel cable loop assembles 179. The hose and socket assembly 177 is device permanently fastened on connector platform 176 to accommodate respective connecting element permanently fastened on each end of repetitive segments of the thermally insulated tubes 72 of closed loop system of the apparatus. The tube and socket assembly 177 can operate as pull-back sleeve (quick connect and disconnect system) and can be additionally secured with safety pin to prevent accidental disconnect. The steel cable loop assembly 179 consists of two sets of eyelets 202 with thimbles formed at each end of the fastening block 171. The two sets of eyelets 202 of the fastening block 171 protrude on upper and lower portion of the connector platform 176. Each leg of each segment of the main steel cable 75 has standard latched sling hooks 55 (not shown in this illustration) on each end and is hooked to the eyelets 202 of the cable and tube connector platform 176. All parts including steel cable 75 can be thermally insulated and coated with anti-corrosion material.

(125) This design of cable and tube connector assembly 175 provides flexibility for repetitive segments of tubes and cables to be added as needed, preferably in pairs for balance and proper distribution of load. This load carrying system 60 provides efficient weight distribution and increases load capacity as length and weight of the apparatus increases.

(126) FIG. 35 is a cross sectional view taken along line 35-35 of FIG. 34. Here are illustrated all elements described in FIG. 34 including the cable and tube connector platform 176, thermally insulated tubes 72 of closed loop system of the apparatus, steel cable loop assembly 179 with fastening blocks 171 and two set of eyelets 202 protruding on upper and lower portion of the connector platform 176. Also, here is illustrated a pair of latched sling hooks 55 which are permanent ending parts on each segment of the main steel cable 75. Here are also illustrated fasteners 57 used also for support of the structure during assembly and disassembly process of the segments.

(127) FIG. 36 is a cross sectional view taken along line 36-36 of FIG. 34, with all elements already explained in FIGS. 33 and 35. This illustration of the cable and tube connector assembly 175 with diameter about 15 inches contains 8 steel cable loop assembly 179 which accommodate 16 steel cables 75 with diameter about 1 inch. Larger diameter of the connector assembly 175 can contain more steel cable loop assembly 179 which would increase load potential and subsequently length of the apparatus.

(128) This invention explains a method of how to use unlimited sources of geothermal energy which has not been used in this way today. This invention explains how to use internal heat of our planet and produce electricity deep down and transmit it to the surface by cable. This invention explains self contained geothermal generator with its basic elements, their shape, form, interactions, their functions and possible applications.

(129) In this presentation, turbines, generator, pumps, control valves, safety relief valves, sensors, lubrication line, wiring and cameras are not illustrated in details but there are many reliable, heat resistant, automatic, fast action pumps and control valves, turbines and generators used in power plants, steam engines, marines industry, and the like that may be applicable in embodiments of the present invention. Further, according to particular embodiments of the present invention, the length of the chambers are not limited to the respective size as represented in the drawing figures of this disclosure, but rather they may be of any desired length. In this presentation are explained and illustrated only new elements and function of the invention. All necessary elements and tools that are used in contemporary drilling technology for drilling wellbores including safety requirements casings and blow out preventer (BOP) should be used if necessary. The present invention can be used in many different applications and environments.

(130) The sizes of elements of this invention, such as the diameter, are limited to drilling technology at the time, diameter of the wells and practical weight of the assembly.

(131) Additionally, particular embodiments of the present invention may use a cable, chain or other suitable means for lowering the geothermal generator into pre-drilled hole. The apparatus can be lowered into the well by filling the well first with water and then lowering the apparatus by gradually emptying the well or controlling buoyancy by filling or emptying the boiler of the apparatus with fluids. Apparatuses of the present invention (SC-GGG and SCI-GHE) during lowering and raising process will be emptied from fluids to reduce weight of the apparatuses and to increase load capacity of the derrick.

(132) Seismicity

(133) Also, the possibility of inducing seismicity is a serious factor to consider during the installation and operation of enhanced geothermal systems. For example, in enhanced geothermal systems that inject water underground, the injected water can accumulate into underground pre-existing pockets (caves) and when critical mass and temperature is reached can induce an explosion which can trigger earthquakes, especially if seismic tension already exists at that area. Embodiments of the present invention do not have the same concern since the working fluid is in a closed loop and would not suffer the same effects of injecting water into underground pre-existing pockets.

(134) Calculations

(135) The SCI-GGG system according to embodiments of the present invention incorporates already proven technology (Boiler, Turbine, Generator, and Condenser). An Organic Rankine Cycle (ORC) has already been in use over the last 30 years. Basically, an ORC operates on two separate flows of hot and cool liquid. The final numbers of the production and operation of the ORC depends of selected location and accessible temperature. In general, in order to operate the system, the ORC needs a minimum necessary heat of the evaporator within the range of 80 C.-140 C. (176 F.-284 F.). The Condenser needs three times the input heat flow and further needs the necessary heat to be less than 30 C. (86 F.). The Differential in temperature needs to be 65 C. (125 F.) less than input heat flow temperature.

(136) Maintenance

(137) The basic maintenance of embodiments of the present invention can be managed from a ground surface through maintenance lines which comprise electrical lines used for controlling automation (valves), sensors, cameras, and the like; and an oil cooling and lubrication line for lubricating moving parts (bearings) with oil filters on the ground surface for easier access. There is also a service line for controlling and maintaining levels of fluids in the boiler and condenser. For general maintenance such as replacement of bearings, turbines or generator, apparatus may be pulled up from the well-bore and refurnished or trashed or replace it with a new apparatus.

(138) Vertical Approach

(139) Embodiments of the system of the present invention promote a progressive vertical approach to reach and utilize heat from hot rocks or other heated surrounding environment rather than horizontal approach used in Enhanced Geothermal System (EGS). EGS is based on exploring certain locations (nests) and injecting water in those locations until heat from hot rocks is depleted (about 4-5 years) and then moving to another (preferably nearby) location and then repeating the process and after 3-5 years returning to previous location which would by that time replenish heat generated from radioactive decay and internal heat.

(140) Because SCI-GGG and Self-Contained In-Ground Heat Exchanger (SCI-GHE) systems use a completely closed loop system, permeability of the rocks, horizontal rock formations and substantial amount of underground water is of lessen concern, but rather these systems can operate in a vertical approach. When cooling of surrounding rocks or environment eventually occurs, it would only be necessary to pull out the apparatus from the well-bore, drill an additional distance to reach hot rocks or surrounding environment and then lower the apparatus at the new depth. The extended depth will result in hotter rock formations and higher heat flux. Eventually, a point will be reached where heat extraction and heat replenishment will be in balance or equilibrium.

(141) Lava Flow/Tube

(142) In certain locations, such as Hawaii, drilling may not be necessary. Two posts on either side of a lava flow/tube can be erected with cable extended between them, like a bridge, and either of apparatuses SCI-GGG and/or SCI-GHE can be lowered close to lava with binary power unit nearby on the ground and electricity can be produced.

(143) Dry Rock & Hydrothermal Reservoir

(144) Although main purpose of the Scientific Geothermal Systems (SCI-GGG & SCI-GHE) is to use limitless dry hot rocks for production of electricity, is not limited to dry hot rocksit can be lowered into existing hydrothermal reservoir.

(145) In another embodiment, the SCI-GHE could be also easily used in reverse order to heat (warm) the ground (or surroundings) if needed. For example, and without limitation, to extract oil, which is in solid state, the oil needs warming in order to be liquefied. Today they are injecting hot water or other necessary fluid or gas (such as CO2) into ground that warms the solidified oil. That water loses a lot of heat on the way down and also gets mixed with the oil and later, when pumped out to the surface, has to be separated from the oil. With a SCI-GHE the ground can be warmed effectively by heating water (fluids) on the ground surface in boiler 220 and circulating it to heat exchanger 168 deep down through thermally insulated pipes 72 so that heat is not lost during fluid circulation. Alternatively, if needed, additional open loop line can be installed to deliver necessary substance, fluid, CO2, etc. to be dispersed through cracks, fissures into surrounded solidify oil formation and be heated by heat exchanger 168 to liquefy oil for easier extraction. The boiler 220 on the ground surface for this purpose can be heated with different source of heat including geothermal if accessible.

(146) Other embodiments include cooling a dysfunctional nuclear reactor after a possible accident. A first coiled pipe (Heat Exchanger 168) may be lowered into a damaged nuclear reactor and a second coiled pipe (Heat Exchanger 182) into nearby cold reservoir, or if nearby an ocean. This can be repeated with many such apparatuses. Several SCI-GHEs may be used to cool the reactor and surrounding area with a closed loop system. This is better than the current approach of pouring water on the reactor with fire truck equipment (or alike) and then collecting runaway water into reservoirs on nearby sites. That is an open loop system and it contaminates the ground as well as possible ground water. Also, water used for it is contaminated and requires careful disposal.

(147) Another embodiment may be used for cooling mines. In some deep mines, miners have problem with heat reaching temperatures over 100 F. A SCI-GHE could operate to cool the surrounding environment within a deep mine. A first coiled pipe (Heat Exchanger 168) could be laid on a walkway or any appropriate locations inside the mine, and a second coiled pipe (Heat Exchanger 182) may be placed up on the ground surface preferably in a cool environment, such as a shaded area or a body of water. The first and second coiled pipes (Heat Exchangers) are connected with thermally insulated pipes 72 to prevent heat/cold exchange in long lines between the Heat Exchangers. Several inline pumps may be required to force fluid flow quickly through the system. It would absorb heat from mine and exchange it outside in the colder environment.

(148) Further, another embodiment includes utilizing oil wells that are abandoned or about to be abandoned. These wells are typically referred to as Stripper Wells or Marginal Wells. These wells are determined to be in this state if they produce less than 10 barrels of oil per day. Most of these wells are very hot and at a depth of several miles. The heat in these wells may be utilized by implementing SCI-GGG and/or SCI-GHE systems. The system may be sized and shaped to fit within the diameter of the well and lowered in to function as described above. A slim, powerful, in-line pump will make fluid flow fast and minimize heat lost during the operation of the system. Additionally, the in-line pump design could be used for pumping oil up on surface from oil wells without underground pressure.
