  • Publication number: 20250146713
    Abstract: Wellbore synthesis techniques are disclosed suitable for use in geothermal applications. Embodiments are provided where open hole drilled wellbores are sealed while drilling in sequenced operations with utilization of phase change materials to form an impervious layer at the wellbore/formation interface in high temperature applications. 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 heat transfer surfaces for maximizing thermal transfer to a circulating working fluid. Formulations for the working and drilling fluids are disclosed.

  • Publication number: 20250146714
    Abstract: A method for controlling temperature maxima and minima from the heel to toe in geothermal well lateral sections. The method includes disposing at least a pair of wells proximately where thermal contact is possible. Working fluid is circulated in one well of the pair in one direction and the working fluid of the second well is circulated in as direction opposite. to the first. In this manner temperature equilibration is attainable to mitigate maxima and minima to result in a substantially more uniform temperature of the working fluids in respective wells and the rock formation area there between. Specific operating protocol is disclosed having regard to the temperature control for maximizing thermal energy recovery.

  • Patent number: 12239453
    Abstract: A system and method for personalized diagnosis of human body surface conditions from images acquired from a mobile camera device. In an embodiment, the system and method is used to diagnose skin, throat and ear conditions from photographs. A system and method are provided for data acquisition based on visual target overlays that minimize image variability due to camera pose at locations of interest over the body surface, including a method for selecting a key image frame from an acquired input video. The method and apparatus may involve the use of a processor circuit, for example an application server, for automatically updating a visual map of the human body with image data. A hierarchical classification system is proposed based on generic deep convolution neural network (CNN) classifiers that are trained to predict primary and secondary diagnoses from labelled training images.

  • Patent number: 12228112
    Abstract: Methods for providing on demand power to an end user in a variety of embodiments are disclosed. Closed loop thermal recovery arrangements are disposed within a geologic formation having a predetermined potential thermal output capacity. A power generation device is incorporated in the loop to recover energy. A working fluid is circulated within the loop at varying flow rates to oscillate thermal output about the predetermined potential thermal output capacity, to produce on demand power where the average thermal output may equal the predetermined potential thermal output capacity.

  • Publication number: 20250034947
    Abstract: A method for drilling a geothermal well in a subterranean zone includes drilling, with a drill string, a wellbore of the geothermal well in the subterranean zone. An inherent temperature of the rock adjacent a rock face at a downhole end of the wellbore is at least 250 degrees Celsius. While drilling, a drilling fluid is flowed at a temperature at the rock face such that a difference between the inherent temperature of the rock adjacent the rock face and the temperature of the drilling fluid at the rock face is at least 100 degrees Celsius.

  • Publication number: 20250027686
    Abstract: A method includes circulating a heat transfer working fluid in a closed loop between a geothermal well residing in a subterranean zone and at least one of a heat exchanger or a turbine. The well is substantially sealed to limit fluid loss of the working fluid into the subterranean zone. While circulating the working fluid, at least one of a viscosity of the working fluid or a pressure differential between the working fluid and the subterranean zone is controlled in relation to a flow of fluid between the subterranean zone and the well.

  • Patent number: 11953346
    Abstract: There is disclosed a system and method for diagnosing plagiocephaly (flat head syndrome, associated primarily with in infants) from photographs of the head. The method and apparatus may involve the use of a processor circuit, for example an application server, for automatically identifying the contour of the head in a plurality of images, then computing geometrical measurements in order quantify plagiocephaly. Photographs are acquired from an overhead view of a head, where the images may be rotated manually or automatically to a standard orientation. For each image, an optimal head contour is identified as minimizing a mathematical cost function combining local image filter responses designed for edge detection and a global model of head contour shape combining smoothness and convexity constrains. Length measurements are then computed from the identified contour, e.g. head diameter, diagonal diameter, and used to quantify the degree of head asymmetry and diagnose plagiocephaly.

  • Publication number: 20240110731
    Abstract: Closed loop wellbore configurations with unrestricted geometry for accommodating irregular or challenging thermal gradients within a thermally productive formation are disclosed. A working fluid is utilized in the loop for extraction of thermal energy there from. The loop and the unrestricted geometry are achieved using magnetic ranging of independent drilling operations which intersect from an inlet well and outlet well to form an interconnecting segment. In conjunction with the directional drilling, conditioning operations are incorporated to condition the rock face, cool the entire system, activate the wellbore for treatment to optimize thermal transfer inter alia. The significant degree of freedom in wellbore configuration is further optimized by the absence of mechanical impediments such as casing or liners in the heat transfer areas.

  • Publication number: 20240035710
    Abstract: Methods and system for geothermal energy harvesting using both conductive and convective heat transfer are provided. A geothermal well is provided with inlet and outlet wellbores and an interconnecting wellbore therebetween, the interconnecting wellbore fluidly connected to a plurality of fluid conduits, such as fractures. The interface of the wellbore and fractures with the surrounding earth may be impermeably sealed with a sealant. A heat transfer fluid is circulated throughout the system to extract thermal energy from the earth by conduction, as well as by convection. By providing the plurality of fluid conduits and by utilizing convective as well as conductive heat transfer, the rate of energy extraction may be increased.
