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.

Geothermal energy systems and processes eliminate or reduce the distance between a geothermal energy source and an electricity generating power plant The systems and processes include heating a primary fluid by absorbing thermal energy from the geothermal energy source in a well to produce a heated primary fluid; conveying the heated primary fluid to the power plant including, a turbine and an electricity generator; driving the turbine by one of: the heated primary fluid; and a secondary fluid that absorbs thermal energy from the heated primary fluid via, a heat exchanger; and driving the electricity generator via, the turbine to generate electricity. The power plant is positioned at one of: inside the well; partially inside the well; at a wellhead above the well; adjacent to the well; on a pad including one or more wells; and between multiple pads including one or more wells in the same field of pads.

A method of installing a tubular heat exchanger into soil includes providing the tubular heat exchanger and screwing the tubular heat exchanger into the soil with an installation apparatus. The installation apparatus may be removed from the soil without removing the tubular heat exchanger from the soil.

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.

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.
