Abstract: A geothermal well includes a borehole formed in a geologic formation. The borehole includes a first portion extending from a first end to a second end and a second portion intersecting the first portion at a first depth. The second portion is exposed to the formation for heating a fluid flowing in the second portion. The well includes an outer string disposed in the first portion where a lower end of the outer string is disposed above the first depth. The well includes an inner string disposed though the outer string and an annulus formed between the inner string and the outer string. The well includes a choke fluidly coupled to at least one of the annulus or the inner string. The choke is configured to regulate return flow of the heated fluid to maintain surface backpressure above a boiling pressure of the heated fluid at surface.

The RVHE may be configured to be located in a plane defined by an injector well and a production well that is defined by a principal stress direction (S1) of a plurality of principal stress directions and a maximum horizontal stress component (SHmax). The RVHE may include one or more stacked laterals oriented along SHmax. Each stacked lateral, of the one or more stacked laterals, may include one or more vertical branches oriented along S1. The RVHE may be configured to extract energy from a non-hydrothermal source of energy.

Abstract: Wellbore synthesis techniques are disclosed suitable for use in geothermal applications. Embodiments are provided where open hole drilled wellbores are sealed while drilling to form an impervious layer at the wellbore/formation interface. The techniques may be chemical, thermal, mechanical, biological and are fully intended to irreversibly damage the formation in terms of the permeability thereof. With the permeability negated, the wellbore may be used to create a closed loop surface to surface geothermal well operable in the absence of well casing for maximizing thermal transfer to a circulating working fluid. Formulations for the working and drilling fluids are disclosed.

Abstract: A tubing is anchored in a boiler casing positioned in a borehole that extends into a magma reservoir. The tubing may include a notch that is secured to a tubing anchor receptacle of the boiler casing. The boiler casing may include a float shoe that helps to prevent or restrict the flow of magma from the magma reservoir into the boiler casing and tubing.

Abstract: Systems and methods for generating and a controller for controlling generation of geothermal power in an organic Rankine cycle (ORC) operation to thereby supply electrical power to one or more of in-field operational equipment, a grid power structure, and an energy storage device. In an embodiment, during hydrocarbon production, a temperature of a flow of heated fluid from a source or working fluid may be determined. If the temperature is above a vaporous phase change threshold of the working fluid, heat exchanger valves may be opened to divert flow of heated fluid to heat exchangers to facilitate heat transfer from the flow of wellhead fluid to working fluid through the heat exchangers, thereby to cause the working fluid to change from a liquid to vapor, the vapor to cause a generator to generate electrical power via rotation of an expander.

Abstract: A thermal reach enhanced geothermal wellbore has a plurality of fissures at a target location that distally extend into the formation and that are at least partially filled with a compacted high-thermal k material. The compacted high-thermal k material terminates on a proximal end of the fissure at the target location of the wellbore and is thermally coupled to a high-thermal conductivity grout or slurry through which heat is conducted to a working fluid that is contained in a closed loop working fluid conduit embedded in the grout or slurry.

Abstract: Disclosed herein are system, apparatus, article of manufacture, method and/or computer program product embodiments, and/or combinations and sub-combinations thereof, for using a thin-bed hot sedimentary aquifer (HSA) in geothermal energy generation applications. An example embodiment operates by pumping, via an extraction well, heated water from an extraction depth of an HSA. The HSA is identified based on a permeability satisfying a threshold permeability range and could even have a thickness equal to or less than about 100 meters. The example embodiment further operates by extracting, via a power generation unit, heat from the heated water to generate power and transform the heated water into cooled water. Subsequently, the example embodiment operates by injecting, via an injection well, the cooled water at an injection depth of the HSA. A first portion of the extraction well and a second portion of the injection well are disposed within the HSA.

Abstract: A drilling rig and methods are provided for using multiple types of drilling when installing geothermal systems. The drilling rig can perform sonic drilling such as percussive sonic drilling and a type of non-sonic drilling. Control switching valves are added to the hydraulics of the drilling rig to selectively provide sufficient flow of hydraulic fluid to motors used in the multiple types of drilling, depending on which type of drilling is currently most efficient for the underground formation being drilled. The water pump and hydraulic motor for such have been designed to handle both types of drilling on a small drilling rig frame, thereby allowing for the drilling to occur in space-constrained environments. A method of recycling water used to remove cuttings during drilling to put back downhole is also provided.
