Patent number: 11918967Abstract: A method for carrying out a thermochemical process includes injecting one or more feed streams into a reaction chamber. The reaction chamber is maintained at a reaction temperature using heat obtained directly from a subterranean heat source. The method includes maintaining the one or more feed streams in the reaction chamber for a residence time to form one or more product streams from the one or more feed streams. The one or more product streams are removed from the reaction chamber.Type: GrantFiled: October 28, 2022Date of Patent: March 5, 2024Assignee: EnhancedGEO Holdings, LLCInventors: Greg Lindberg, Kimberly C. Conner

Patent number: 11912573Abstract: A method for producing hydrogen by thermochemical splitting of water includes injecting one or more feed streams of water into a reaction chamber. The method further includes using a molten salt heated by a subterranean heat source to carry out the thermochemical splitting of water to form hydrogen and oxygen in the reaction chamber. The formed products are subsequently removed from the reaction chamber. Hydrogen formed in the reaction chamber may be used in a downstream process to generate hydrocarbons.Type: GrantFiled: March 24, 2023Date of Patent: February 27, 2024Assignee: EnhancedGEO Holdings, LLCInventors: Greg Lindberg, Kimberly C. Conner

Patent number: 11913679Abstract: A geothermal system is used for obtaining heated heat transfer fluid, such as steam, via heat transfer with an underground reservoir of magma. The geothermal system includes a wellbore extending between a surface and into an underground chamber formed in a reservoir of magma. The chamber may be formed by injecting a fluid at an increased pressure into underground magma to form a cavity that acts as the underground chamber.Type: GrantFiled: March 2, 2023Date of Patent: February 27, 2024Assignee: EnhancedGEO Holdings, LLCInventors: Greg Lindberg, Kimberly C. Conner, Scott Hall

Patent number: 11905797Abstract: Wellbore for extracting heat from magma and a corresponding method. The method includes the steps of drilling a borehole from a surface and towards a magma chamber; supplying a drilling fluid to an interface between a drill bit and a terminal end of the borehole during drilling; terminating the drilling in response to the borehole achieving a predetermined depth; and supplying a thermodynamic fluid into the borehole to maintain the borehole while completing the wellbore. The drilling fluid lifts cuttings out of the borehole and quenches magma to form a solid phase material that can be cut by the drill bit.Type: GrantFiled: February 3, 2023Date of Patent: February 20, 2024Assignee: EnhancedGEO Holdings, LLCInventors: Greg Lindberg, Kimberly C. Conner

Patent number: 11905814Abstract: A method for preparing a geothermal system involves preparing a wellbore that extends into an underground magma reservoir. Characteristics of the drilling process and the borehole are monitored to detect when the magma reservoir is reached, such that specially configured drilling operations can be performed to drill to a target depth within the magma reservoir.Type: GrantFiled: September 27, 2023Date of Patent: February 20, 2024Assignee: EnhancedGEO Holdings, LLCInventors: Benjamin Chris Smith, James Michael Browning, Randall Howard Hornbaker, Kevin Martin Stone, Georgios Evangelatos, Shamsul Abedin Al-Tomal, Andrew Nguyen

Patent number: 11897828Abstract: A reaction system includes a wellbore extending from a surface into a subterranean heat source. The reaction system further includes a reaction chamber configured to be maintained at a reaction temperature using heat from the subterranean heat source. The reaction system further includes one or more inlet conduits. The inlet conduits are configured to provide one or more feed streams to the reaction chamber. The reaction system also includes outlet conduits configured to allow flow of one or more product streams.Type: GrantFiled: March 3, 2023Date of Patent: February 13, 2024Assignee: EnhancedGEO, Holdings, LLCInventors: Greg Lindberg, Kimberly C.

Patent number: 11852383Abstract: System, method, and apparatus for harnessing geothermal power from superhot geothermal fluid (SHGF) and magma reservoirs. An exemplary apparatus can include a well screen coupled to an end of a casing string. The well screen, which is at least partially submerged within an underground reservoir, defines a volume in the underground reservoir that can be filled with superhot geothermal fluid. A slidable casing is aligned coaxially with the well screen and configured to be repositioned relative to the well screen. A draw pipe extending through the slidable casing is configured to convey SHGF from the underground reservoir towards the surface in response to the slidable casing being repositioned to obstruct more of a set of apertures in the well screen and an increase in pressure within a cavity of the slidable casing.Type: GrantFiled: January 20, 2023Date of Patent: December 26, 2023Assignee: ENHANCEDGEO HOLDINGS, LLCInventors: Greg Lindberg, Kimberly C.

Patent number: 11841172Abstract: System, method, and apparatus for harnessing geothermal power from superhot geothermal fluid (SHGF) and magma reservoirs. An exemplary embodiment is directed to a cased wellbore includes a well casing suspended within a borehole that extends between a surface and an underground reservoir of magma and a boiler casing housed within the well casing and extending between the surface and the underground reservoir of magma. The boiler casing has a first end submerged within the underground reservoir of magma and a terminal end opposite to the first end. The cased wellbore also includes a fluid conduit housed within the boiler casing and configured to deliver a liquid-phase fluid to the terminal end of the boiler casing. A temperature and a pressure at the terminal end of the boiler casing converts the liquid-phase fluid into a gas-phase fluid that travels through the boiler casing towards the surface. The cased wellbore also includes a well head connected to the first end of the boiler casing.Type: GrantFiled: January 20, 2023Date of Patent: December 12, 2023Assignee: EnhancedGEO Holdings, LLCInventors: Greg Lindberg, Kimberly C.
