- the present invention also generally relates to producing non-hydrocarbon materials from a formation prior to hydrocarbon material production to reduce generation of carbon dioxide, to increase permeability, to increase porosity, and/or to improve heat transfer characteristics in the formation
- Hydrocarbons obtained from subterranean (e.g., sedimentary) formations are often used as energy resources, as feedstocks, and as consumer products.
- Concerns over depletion of available hydrocarbon resources and declining overall quality of produced hydrocarbons have led to development of processes for more efficient recovery, processing and/or use of available hydrocarbon resources.
- In situ processes may be used to remove hydrocarbon materials from subterranean formations. Chemical and/or physical properties of hydrocarbon material within a subterranean formation may need to be changed to allow hydrocarbon material to be more easily removed from the subterranean formation.
- the chemical and physical changes may include in situ reactions that produce removable fluids, composition changes, solubility changes, density changes, phase changes, and/or viscosity changes of the hydrocarbon material within the formation.
- a fluid may be, but is not limited to, a gas, a liquid, an emulsion, a slurry, and/or a stream of solid particles that has flow characteristics similar to liquid flow.
- Hydrocarbons within a hydrocarbon containing formation may be converted in situ within the formation to yield a mixture of relatively high quality hydrocarbon products, hydrogen, and/or other products.
- One or more heaters may be used to heat a portion of the hydrocarbon containing formation to temperatures that allow pyrolysis of the hydrocarbons.
- Hydrocarbons, hydrogen, and other formation fluids may be removed from the formation through one or more production wells.
- formation fluids may be removed in a vapor phase.

- Treatment area 102 may be cooled to a temperature near the boiling point of water.
- Treatment area 102 may be further cooled to a temperature at which water will begin to condense within the formation (i.e., a temperature below a boiling temperature of water). Removing the water or other solvents from treatment area 102 may also remove any materials remaining in the treatment area that are soluble in water.
- the water may be pumped out of treatment area 102 through production well 108 and/or heater wells 110. Additional water and/or other solvents may be injected into treatment area 102. This injection and removal of water may be repeated until a sufficient water quality within treatment area 102 is reached. Water quality may be measured at injection wells 114, heater wells 110, and/or production wells 108.
- the sufficient water quality may be a water quality that substantially matches a water quality of treatment area 102 prior to treatment.

- Nahcolite within the formation may form an aqueous solution following the injection of water.
- the aqueous solution may be removed from the formation through a heater well, injection well, or production well.
- Removing the nahcolite removes material that would otherwise form carbon dioxide during heating of the formation to pyrolysis temperature.
- Removing the nahcolite may also inhibit the endothermic dissociation of nahcolite during an in situ conversion process.
- Removing the nahcolite may reduce mass within the formation and increase a permeability of the formation. Reducing the mass within the formation may reduce the heat required to heat to temperatures needed for the in situ conversion process. Reducing the mass within the formation may also increase a speed at which a heat front within the formation moves.
- Increasing the speed of the heat front may reduce a time needed for production to begin.
- slightly higher temperatures may be used in the formation (e.g., above about 120 °C) and the nahcolite may begin to decompose.
- nahcolite may be removed from the formation as a soda ash (Na 2 C0 3 ).
- Nahcolite removed from the formation may be heated in a surface facility to form sodium carbonate and/or sodium carbonate brine. Heating nahcolite will form sodium carbonate according to the equation:
- the sodium carbonate brine may be used to solution mine alumina.
- the carbon dioxide produced may be used to precipitate alumina.
- soda ash is produced from solution mining of nahcolite, the soda ash may be transported to a separate facility for treatment. The soda ash may be transported through a pipeline to the separate facility.
- the formation may be treated using an in situ conversion process to produce hydrocarbon fluids from the formation. Remaining water is drained from the solution mining area through dewatering wells prior to heating to in situ conversion process temperatures. During the in situ conversion process, a portion of the dawsonite within the formation may decompose. Dawsonite will typically decompose at temperatures above about 270 °C according to the reaction:
- the alumina formed from EQN.2 will tend to be in the form of chi alumina.
- Chi alumina is relatively soluble in basic fluids.
- Alumina within the formation may be solution mined using a relatively basic fluid following reaching pyrolysis temperatures of hydrocarbons within the formation.
- a dilute sodium carbonate brine such as 0.5 Normal Na 2 C0 3
- the sodium carbonate brine may be obtained from solution mining the nahcolite.
- Obtaining the basic fluid by solution mining the nahcolite may significantly reduce costs associated with obtaining the basic fluid.
- the basic fluid may be injected into the formation through a heater well and/or an injection well.
- the basic fluid may form an alumina solution that may be removed from the formation.
- the alumina solution may be removed through a heater well, injection well, or production well. An excess of basic fluid may have to be maintained throughout an alumina solution mining process.
- Alumina may be extracted from the alumina solution in a surface facility.
- carbon dioxide may be bubbled through the alumina solution to precipitate the alumina from the basic fluid.
- Carbon dioxide may be obtained from the in situ conversion process or from decomposition of the dawsonite during the in situ conversion process.
- a formation may include portions that are significantly rich in either nahcolite or dawsonite only.
- a formation may contain significant amounts of nahcolite (e.g., greater than about 20 weight %) in a depocenter of the formation.
- the depocenter may contain only about 5 weight % or less dawsonite on average.
- a weight percent of dawsonite may be about 10 weight % or even as high as about 25 weight %.
- it may be advantageous to solution mine for nahcolite only in nahcolite-rich areas, such as the depocenter, and solution mine for dawsonite only in the dawsonite-rich areas, such as the bottom layers.
- This selective solution mining may significantly reduce a fluid cost, heating cost, and/or equipment cost associated with operating a solution mining process.
- Nordstrandite (Al(OH) 3 ) is another aluminum bearing mineral that may be found in a formation.
- Nordstrandite is typically found in formations that also contain dawsonite and may be solution mined simultaneously with the dawsonite. ⁇
- Solution mining dawsonite and nahcolite may be a simple process that produces only aluminum and soda ash from a formation. It may be possible to use some or all hydrocarbons produced from an in situ conversion process to produce direct current (DC) electricity on a site of the formation.
- the produced DC electricity may be used on the site to produce aluminum metal from the alumina using the Hall process.
- Aluminum metal may be produced from the alumina by melting the alumina in a surface facility on the site. Generating the DC electricity at the site may save on costs associated with using hydrotreaters, pipelines, or other surface facilities associated with transporting and/or treating hydrocarbons produced from the formation using the in situ conversion process.
- Some formations may also contain amounts of trona.
- Trona is a sodium sesquicarbonate
- Treatments for solution mining of trona may be substantially similar to treatments used for solution mining of nahcolite.
- Trona may typically be found in kerogen formations such as oil shale formations in Wyoming.
- solution mining may be used to recover non-hydrocarbon materials prior ⁇ to heating the formation to hydrocarbon pyrolysis temperatures. Examples of such materials and formations may include nahcolite and dawsonite in Green River oil shale, trona in Wyoming oil shale, or ammonia from buddingtonite in the Condor deposit in Queensland, Australia.
- non-hydrocarbon materials that may be solution mined include carbonates (e.g., trona, eitelite, burbankite, shortite, pirssonite, gaylussite, norsethite, thermonatrite), phosphates, carbonate-phosphates (e.g., bradleyite), carbonate chlorides (e.g., northupite), silicates
- carbonates e.g., trona, eitelite, burbankite, shortite, pirssonite, gaylussite, norsethite, thermonatrite
- phosphates e.g., carbonate-phosphates (e.g., bradleyite)
- carbonate chlorides e.g., northupite
- silicates e.g., silicates
- Solution mining prior to hydrocarbon pyrolysis may increase a permeability of the formation and or improve other features (e.g., porosity) of the formation for the in situ process. Solution mining may also remove significant portions of compounds that will tend to endothermically dissociate at increased temperatures. Removing these endothermically dissociating compounds from the formation tends to decrease an amount of heat input required to heat the formation.
- phosphate may be removed from marine oil shale formations such as the Phosphoria formation in Idaho. Phosphate may have a weight percentage up to about 20 weight % or about 30 weight % in these formations. Recovered phosphate may be used in combination with ammonia and/or sulfur produced during the in situ conversion process to produce useable materials such as fertilizer.
- Metals may also be recoverable from marine oil shale deposits. Metals such as uranium, chromium, cobalt, nickel, gold, zinc, etc. may be recovered from marine oil shale formations. Metals may also be found in certain bitumen deposits. For example, bitumen deposits may contain amounts of vanadium, nickel, uranium, platinum, or gold.
- a simulation was used to predict the effects of solution mining nahcolite and dawsonite from an oil shale formation.
- the simulation predicts the effect on oil production and energy requirements for producing hydrocarbons from the oil shale formation using an in situ conversion process.
- the kinetics of decomposition of nahcolite and dawsonite were used in the simulation.
- Nahcolite decomposed into soda ash, carbon dioxide, and water The frequency factor for the decomposition was 7.83 x 10 15 (L/days).
- the activation energy was 1.015 x 10 5 joules per gram mole (J/gmol).
- the heat of reaction was -62,072 J/gmol.
- the frequency factor for the decomposition was 1.0 x 10 20 (L/days).
- the activation energy was 2.039 x 10 5 J/gmol.
- the heat of reaction was -151,084 J/gmol.
- FIG. 2 illustrates cumulative oil production (m 3 ) and cumulative heat input (kilojoules) versus time (years) using an in situ conversion process for solution mined oil shale and for pre-solution mined oil shale.
- Curve 112 illustrates cumulative oil production for non-solution mined oil shale.
- Curve 114 illustrates cumulative heat input for non-solution mined oil shale.
- Curve 116 illustrates cumulative oil shale production for solution mined oil shale.
- Curve 118 illustrates cumulative heat input for solution mined oil shale.
- the non-solution mined oil shale was assumed to have a 0.125 liters per kilogram (L/kg) Fischer Assay with 5% dawsonite and 20% nahcolite, a 1.9% fracture porosity, and a 65% water saturation.
- the solution mined oil shale was found to have a 0.125 L/kg Fischer Assay with 5% dawsonite and 0% nahcolite, a 29% porosity (created from removal of the nahcolite), and a 1.5 % water saturation.
- the solution mined oil shale was assumed to have a relatively high permeability, which reduces the water saturation to 1.5%.
- the simulation predicts that oil production in solution mined oil shale 116 begins sooner and is faster than oil production in the non-solution mined oil shale 112. For example, after about 9 years, solution mined oil shale has produced about 9500 m 3 of oil, while non-solution mined oil shale has only produced about 1500 m 3 of oil. Non-solution mined oil shale will produce about 9500 m 3 of oil in about 12 years, 3 years later than solution mined oil shale.
- the simulation predicts that less heat is needed to produce oil from solution mined oil shale 118 than from non-solution mined oil shale 114. For example, after about 9 years, solution mined oil shale has required about 9 x 10 10 kJ of heat input, while non-solution mined oil shale has required about 1.1 x 10 11 kJ of heat input.
- a soluble compound e.g., phosphates, bicarbonates, alumina, metals, minerals, etc.

Heat may be provided in the form of hot water or steam produced from the formation. In other embodiments, heat may be transferred by heat exchangers to the first fluid. In other embodiments, a heated portion or component from the mixture may be mixed with the first fluid to heat the fluid.
- a component from the mixture produced from the hydrocarbon containing formation may be used to adjust a quality of a first fluid.
- acidic compounds e.g., carbonic acid, organic acids
- basic compounds e.g., ammonium, carbonate, or hydroxide compounds

- the soluble compound may be separated from the second fluid stream and treated or processed. Portions of the second fluid may be recycled into the formation.
- heat from the hydrocarbon containing formation may migrate and heat at least a portion of the soluble compound containing formation.
- the soluble compound containing formation may be substantially near, adjacent to, or intermixed with the hydrocarbon containing formation.
- the heat that migrates may be useful to enhance the solubility of the soluble compound when the first fluid is applied to the soluble compound containing formation.
- Heat that migrates from the hydrocarbon containing formation may be recovered instead of being lost. Reusing openings (wellbores) for different applications may be cost effective in certain embodiments.
- openings used for providing the heat sources (or from producing from the hydrocarbon containing formation) may be used to provide the first fluid to the soluble compound containing formation or to produce the second fluid from the soluble compound containing formation.
- a solution may be first provided to, or produced from, a formation in a solution mining operation.
- the solution may be provided or produced through openings.
- One or more of the same openings may later be used as heater wells or producer wells for an in situ conversion process.
- one or more of the same openings may be used again for providing a first fluid to the same formation layer or to a different formation layer.
- the openings may be used to solution mine components such as nahcolite. These openings may further be used as heater wells or producer wells in the hydrocarbon containing formation. Then the openings may be used to provide the first fluid to either the hydrocarbon containing layer or a different layer at a different depth than the hydrocarbon containing layer.
- These openings may also be used when producing second fluid from the solution compound containing formation.
- FIG. 3 shows a schematic view of an embodiment of a portion of an in situ conversion system for treating a hydrocarbon containing formation.
- Heat sources 110 may be placed within at least a portion of the hydrocarbon containing formation.
- Heat sources 110 may include, for example, electric heaters such as insulated conductors, conductor-in-conduit heaters, surface burners, flameless distributed combustors, and/or natural distributed combustors. Heat sources 110 may also include other types of heaters.
- Heat sources 110 may provide heat to at least a portion of a hydrocarbon containing formation.
- Energy may be supplied to the heat sources 110 through supply lines 120.
- the supply lines may be structurally different depending on the type of heat source or heat sources being used to heat the formation.
- Supply lines for heat sources may transmit electricity for electric heaters, may transport fuel for combustors, or may transport heat exchange fluid that is circulated within the formation.
- Production wells 108 may be used to remove formation fluid from the formation. Formation fluid produced from production wells 108 may be transported through collection piping 122 to treatment facilities 124. Formation fluids may also be produced from heat sources 110. For example, fluid may be produced from heat sources 110 to control pressure within the formation adjacent to the heat sources. Fluid produced from heat sources 110 may be transported through tubing or piping to collection piping 122 or the produced fluid may be transported through tubing or piping directly to treatment facilities 124. Treatment facilities 124 may include separation units, reaction units, upgrading units, fuel cells, turbines, storage vessels, and other systems and units for processing produced formation fluids. An in situ conversion system for treating hydrocarbons may include barrier wells 104. Barrier wells 104 may, in some embodiments, be capture wells, dewatering wells, freeze wells, and/or isolation wells.
- a pattern of heat sources will often include many units of heat sources. There will typically be many heated portions, as well as many selected sections within the pattern of heat sources. Heat may be allowed to transfer from one or more of the heat sources to part of the formation substantially by conduction. In some embodiments, a large spacing may provide for a relatively slow heating rate of hydrocarbon material. The slow heating rate may allow for pyrolysis of hydrocarbon material with minimal coking or no coking within the formation away from areas in the vicinity of the heat sources. Heating from heat sources allows the selected section to reach pyrolysis temperatures so that all hydrocarbons within the selected section may be subject to pyrolysis reactions.
- a majority of pyrolysis fluids are produced when the selected section is within a range from about 0 m to about 25 m from a heat source.
- a heat source in addition to heat sources 110, one or more production wells 108 will typically be placed within the portion of the hydrocarbon containing formation. Formation fluids may be produced through production well 108.
- production well 108 may include a heat source. The heat source may heat the portions of the formation at or near the production well and allow for vapor phase removal of formation fluids. The need for high temperature pumping of liquids from the production well may be reduced or eliminated. Avoiding or limiting high temperature pumping of liquids may significantly decrease production costs.
- Providing heating at or through the production well may: (1) inhibit condensation and/or refluxing of production fluid when such production fluid is moving in the production well proximate the overburden, (2) increase heat input into the formation, and/or (3) increase formation permeability at or proximate the production well.
- an amount of heat supplied to production wells is significantly less than an amount of heat applied to heat sources that heat the formation. Fluid generated within a hydrocarbon containing formation may move a considerable distance through the hydrocarbon containing formation as a vapor. The considerable distance may be over 1000 m depending on various factors (e.g., permeability of the formation, properties of the fluid, temperature of the formation, and pressure gradient allowing movement of the fluid). Due to increased permeability in formations subjected to in situ conversion and formation fluid removal, production wells may only need to be provided in every other unit of heat sources or every third, fourth, fifth, or sixth units of heat sources.
- Embodiments of a production well may include valves that alter, maintain, and/or control a pressure of at least a portion of the formation.
- Production wells may be cased wells.
- Production wells may have production screens or perforated casings adjacent to production zones.
- the production wells may be surrounded by sand, gravel or other packing materials adjacent to production zones.
- Production wells 108 may be coupled to treatment facilities 124, as shown in FIG. 3.
- production wells may be operated such that the production wells are at a lower pressure than other portions of the formation.
- a vacuum may be drawn at the production wells. Maintaining the production wells at lower pressures may inhibit fluids in the formation from migrating outside of the in situ treatment area.
- Triangular patterns tend to provide more uniform heating to a portion of the formation in comparison to other patterns such as squares and/or hexagons. Triangular patterns tend to provide faster heating to a predetermined temperature in comparison to other patterns such as squares or hexagons. The use of triangular patterns may result in smaller volumes of a formation being overheated.
- a plurality of units of heat sources may be arranged substantially adjacent to each other to form a repetitive pattern of units over an area of the formation.
- triangular patterns may be arranged substantially adjacent to each other in a repetitive pattern of units by inverting an orientation of adjacent triangles.
- Other patterns of heat sources 108 may also be arranged such that smaller patterns may be disposed adjacent to each other to form larger patterns.
- heater wells may be substantially horizontal while production wells may be vertical, or vice versa.
- wells may be aligned along dip or strike or oriented at an angle between dip and strike.
- the spacing between heat sources may vary depending on a number of factors. The factors may include, but are not limited to, the type of a hydrocarbon containing formation, the selected heating rate, and/or the selected average temperature to be obtained within the heated portion. In some well pattern embodiments, the spacing between heat sources may be within a range of about 5 m to about 25 m. In some well pattern embodiments, spacing between heat sources may be within a range of about 8 m to about 15 m.
- Subsurface pressure in a hydrocarbon containing formation may correspond to the fluid pressure generated within the formation. Heating hydrocarbons within a hydrocarbon containing formation may generate fluids by pyrolysis. The generated fluids may be vaporized within the formation. Vaporization and pyrolysis reactions may increase the pressure within the formation.
- Fluids that contribute to the increase in pressure may include, but are not limited to, fluids produced during pyrolysis and water vaporized during heating. As temperature within a selected section of a heated portion of the formation increases, a pressure within the selected section may increase as a result of increased fluid generation and vaporization of water. Controlling a rate of fluid removal from the formation may allow for control of pressure in the formation.
- pressure within a selected section of a heated portion of a hydrocarbon containing formation may vary depending on factors such as depth, distance from a heat source, a richness of the hydrocarbons within the hydrocarbon containing formation, and/or a distance from a producer well. Pressure within a formation may be determined at a number of different locations (e.g., near or at production wells, near or at heat sources, or at monitor wells).
- Heating of a hydrocarbon containing formation to a pyrolysis temperature range may occur before substantial permeability has been generated within the hydrocarbon containing formation.
- An initial lack of permeability may inhibit the transport of generated fluids from a pyrolysis zone within the formation to a production well.
- a fluid pressure within the hydrocarbon containing formation may increase proximate a heat source.
- Such an increase in fluid pressure may be caused by generation of fluids during pyrolysis of at least some hydrocarbons in the formation.
- the increased fluid pressure may be released, monitored, altered, and/or controlled through the heat source.
- the heat source may include a valve that allows for removal of some fluid from the formation.
- the heat source may include an open wellbore configuration that inhibits pressure damage to the heat source.
- pressure within the formation may be controlled by controlling production rate from the production wells.
- a back pressure may be maintained at production wells or at selected production wells to maintain a selected pressure within the heated portion.
- pressure may be increased within a selected section of a portion of a hydrocarbon containing formation to a selected pressure during pyrolysis.
- a selected pressure may be within a range from about 2 bars absolute to about 72 bars absolute or, in some embodiments, 2 bars absolute to 36 bars absolute. Alternatively, a selected pressure may be within a range from about 2 bars absolute to about 18 bars absolute.
- a majority of hydrocarbon fluids may be produced from a formation having a pressure within a range from about 2 bars absolute to about 18 bars absolute. The pressure during pyrolysis may vary or be varied.
- the pressure may be varied to alter and/or control a composition of a formation fluid produced, to control a percentage of condensable fluid as compared to non-condensable fluid, and/or to control an API gravity of fluid being produced. For example, decreasing pressure may result in production of a larger condensable fluid component.
- the condensable fluid component may contain a larger percentage of olefins.
- increased pressure due to fluid generation may be maintained within the heated portion of the formation. Maintaining increased pressure within a formation may inhibit formation subsidence during in situ conversion. Increased formation pressure may promote generation of high quality products during pyrolysis. Increased formation pressure may facilitate vapor phase production of fluids from the formation.
- Increased pressure in the formation may also be maintained to produce more and/or improved formation fluids.
- significant amounts (e.g., a majority) of the hydrocarbon fluids produced from a formation may be non-condensable hydrocarbons.
- Pressure may be selectively increased and/or maintained within the formation to promote formation of smaller chain hydrocarbons in the formation.
- Producing small chain hydrocarbons in the formation may allow more non-condensable hydrocarbons to be produced from the formation.
- the condensable hydrocarbons produced from the formation at higher pressure may be of a higher quality (e.g., higher API gravity) than condensable hydrocarbons produced from the formation at a lower pressure.
- Maintaining increased pressure within a heated portion of the formation may surprisingly allow for production of large quantities of hydrocarbons of increased quality. Maintaining increased pressure may promote vapor phase transport of pyrolyzation fluids within the formation. Increasing the pressure often permits production of lower molecular weight hydrocarbons since such lower molecular weight hydrocarbons will more readily transport in the vapor phase in the formation.
- a portion of a hydrocarbon containing formation may be heated to increase a partial pressure of H 2 .
- an increased H 2 partial pressure may include H 2 partial pressures in a range from about 0.5 bars to about 7 bars.
- an increased H 2 partial pressure range may include H 2 partial pressures in a range from about 5 bars to about 7 bars.
- a majority of hydrocarbon fluids may be produced wherein a H 2 partial pressure is within a range of about 5 bars to about 7 bars.
- a range of H 2 partial pressures within the pyrolysis H 2 partial pressure range may vary depending on, for example, temperature and pressure of the heated portion of the formation.
