Methods and systems for constructing an enhanced closed-loop geothermal system for heat transfer from a region of a subsurface. The method may include obtaining a first wellbore extending from a surface and penetrating the region of the subsurface. The method further includes enlarging at least a first portion of the first wellbore to a first pre-determined wellbore diameter and inserting a casing string having an expandable casing section into the first wellbore such that the expandable casing section is disposed within the first portion. The method also includes expanding the expandable casing section within the first portion and inserting a closed-loop geothermal system having a fluid conduit into the first wellbore yielding the enhanced closed-loop geothermal system.
Resumen de: US2025347427A1
An energy storage system and method for operating same are provided. The system comprises a first heat exchanger for heating a first heat transfer fluid in fluid communication with a ground heat exchanger and a heat pump; and a first circulation device for circulating the first heat transfer fluid. An energy collector is in fluid communication with the first heat exchanger for transferring energy collected by an energy collector to the first heat exchanger with a second heat transfer fluid circulate by a second circulation device. A controller actuates the first and second circulation devices to circulate the first and second heat transfer fluids. If temperature sensor data of the first and second heat transfer fluids entering the first heat exchanger is above a threshold valve, the controller continues to actuate first and second circulation devices to circulate the first and second heat transfer fluids.

Methods and systems for constructing an enhanced closed-loop geothermal system (300) for heat transfer from a region of a subsurface (160). The method may include obtaining a first wellbore (102) extending from a surface (130) and penetrating the region of the subsurface (160). The method further includes enlarging at least a first portion (402) of the first wellbore (102) to a first pre-determined wellbore diameter and inserting a casing string (120) having an expandable casing section (319) into the first wellbore (102) such that the expandable casing section (319) is disposed within the first portion (402). The method also includes expanding the expandable casing section (319) within the first portion (402) and inserting a closed-loop geothermal system having a fluid conduit (314) into the first wellbore (102) yielding the enhanced closed-loop geothermal system (300).
