A method for recompleting a well is applied to a well such that the recompleted well can thermally transfer geothermal energy to surface. The recompleting method can comprise steps to hydraulically isolate a wellbore using a hydraulic isolation means, and enhance the thermal conductivity of a reservoir in which the wellbore is located by inserting a thermal material into the reservoir that displaces a reservoir fluid having a lower thermal conductivity than the thermal material.

Disclosed herein are various embodiments of systems for drilling and operating a well which may have dual uses. The well may be drilled and operated as a geothermal well using a hybrid approach where a heat transfer fluid is injected into a hot rock formation but is not removed, and heat is extracted using a closed loop method. The geothermal well is then evaluated for use as a carbon dioxide sequestration well. In other embodiments, the well is drilled as a carbon dioxide sequestration well and then evaluated for its potential for generating geothermal energy using a hybrid approach where supercritical carbon dioxide is injected into a hot rock formation but is not removed, and heat is extracted using a closed loop method. Both horizontal and vertical wells are disclosed, in sedimentary rocks and in basement granite.

A wellhead container for a geothermal system includes a base configured to engage a bottom of a recess within a ground. The recess extends vertically from the bottom of the recess to a surface of the ground, the base includes at least one first opening, and the at least one first opening is configured to receive a drilling string. The wellhead container includes a top configured to support a load applied by a drilling machine to the wellhead container. The top includes second openings, and each second opening is configured to receive the drilling string. The wellhead container includes a sidewall extending along a vertical axis between the base and the top. The sidewall is configured to position an upper surface of the top substantially flush with the surface of the ground, and the sidewall is configured to transfer at least a portion of the load to the base.

The disclosed invention concerns a method for installing and operating a thermal well (110) heat carrier transport system (100). A first flexible tubular part (120) is provided into and along a thermal well (110), a second flexible tubular part (130) is provided into the first flexible tubular part (120) and a third open ended tubular part (140) is provided into the second flexible tubular part (130). During installation and operation an installation liquid and heat carrier, respectively, is provided into the second flexible tubular part at an overpressure sufficient to press the first flexible tubular part (120) radially against the inner all of the thermal well (110) in all radial directions. The invention also concerns a system.

The invention provides in one embodiment a heat exchanger module (1) comprising a) a flexible support (100); b) at least one tubular member (200) having its main axis substantially parallel with the plane of the flexible support (100); c) a conductive flexible matrix (300) embedding the at least one tubular member (200); and d) a flexible case (400) enwrapping the flexible support (100), the at least one tubular member (200) and the conductive flexible matrix (300). A coating for a built environment comprising a plurality of heat exchanger modules (1) can be implemented, as well as a system further including pumping means (600). The invention also foresees a method for providing heat exchange processes between the heat exchanger module (1), the coating or the system of the invention and a built environment.

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 hot sedimentary aquifer (HSA) in geothermal energy generation applications. An example embodiment operates by pumping, via multiple extraction wells, heated water from one or more extraction depths of an HSA. The HSA is identified based on a permeability satisfying a threshold permeability range. 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 multiple injection wells, the cooled water at one or more injection depths of the HSA.
