Patent number: 12241660Abstract: Operational protocol sequences for recovering energy from a thermally productive formation are disclosed. Sealing, drilling, multiranging, power production and distribution techniques in predetermined sequences for well formation are utilized to recover energy regardless of thermal gradient variation, formation depth and permeability and other anomalies or impedances.Type: GrantFiled: June 26, 2020Date of Patent: March 4, 2025Assignee: Eavor Technologies Inc.Inventors: Matthew Toews, Bailey Schwarz, Derek Riddell, Paul Cairns, John Redfern, Andrew Curtis-Smith, Jonathan Hale, Peter Andrews

Patent number: 12228112Abstract: 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. Integrations with intermittent renewable energy sources are provided which optimize performance and distribution.Type: GrantFiled: September 16, 2022Date of Patent: February 18, 2025Assignee: Eavor Technologies Inc.Inventors: Matthew Toews, Bailey Schwarz, John Redfern, Paul Cairns

Patent number: 11959356Abstract: 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.Type: GrantFiled: February 4, 2022Date of Patent: April 16, 2024Assignee: Eavor Technologies Inc.Inventors: Matthew Toews, Paul Cairns, Peter Andrews, Andrew Curtis-Smith, Jonathan Hale

Patent number: 11808488Abstract: 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.Type: GrantFiled: October 12, 2021Date of Patent: November 7, 2023Assignee: Eavor Technologies Inc.Inventors: Paul Cairns, Matthew Toews, John Redfern

Patent number: 11661821Abstract: Methods for drilling in higher temperature rock formations such as geothermal formations with phase change material augmented drilling fluid include observing flow rate of the augmented fluid. Heat exchange between the annulus returning fluid and tubular fluid can be minimized thereby facilitating a cooler fluid for contact with a rock face being drilled. The cooling assists in pre-fracturing the rock face prior to destruction by the drill bit.Type: GrantFiled: November 11, 2020Date of Patent: May 30, 2023Assignee: Eavor Technologies Inc.Inventors: Matthew Toews, Michael Holmes
