Abstract: A geothermal plant, for extracting energy from a geothermal reservoir located below the ocean bottom, includes a floating platform; a riser that extends from a well drilled into the geothermal reservoir, to the floating platform; an electrical pump having a mechanical actuation part located in a bore of the riser, and an electronic part located outside the riser, wherein the electrical pump is configured to pump a geothermal liquid from the geothermal reservoir to the floating platform; and a power plant located on the floating platform and configured to use a steam produced by the geothermal liquid to generate electrical power. The electrical pump is placed at a depth of the riser where the geothermal liquid is in a single-phase.

Abstract: A heat extraction system for extracting heat from a reservoir, the system including a co-axial tool configured to be placed underground, the co-axial tool having an outer pipe and an inner pipe located within the outer pipe, each of the outer pipe and the inner pipe being connected to a shoe so that a fluid flows through an annulus defined by the inner and outer pipes, reaches the shoe, and flows through a bore of the inner pipe; and a power generator fluidly connected to a chemical processing unit to receive a fluid, and also fluidly connected with a first port to the inner pipe and with a second port to the outer pipe of the co-axial tool. A temperature difference of the fluid at the power generator and at the co-axial tool drives the power generator to generate energy.

Abstract: A method for estimating a location on the ocean bottom for drilling a well for exploring a geothermal reservoir, includes receiving data sets indicative of the geothermal reservoir and ocean conditions above the geothermal reservoir, selecting plural factors represented in the data sets and indicative of the geothermal reservoir, associating each factor of the plural factors with one or more criterion that indicates a desirability of drilling the well at the location of the geothermal reservoir, assigning to each factor an individual score based on the one or more criterion, aggregating the individual scores into a single overall score, and selecting the location of the geothermal reservoir when the single overall score is larger than a given threshold.
