METHOD FOR GEOPHYSICAL EXPLORATION OF GEOTHERMAL DEPOSITS OF UNDERGROUND WATER Russian patent published in 2025 - IPC G01V11/00 

FIELD: geophysics.

SUBSTANCE: invention relates to geophysics and can be used to search for geothermal deposits of underground water. Aeromagnetic survey is carried out using an unmanned aerial vehicle (UAV) and a pedestrian quantum magnetometer-gradiometer used as a payload for the UAV. Thermal imaging is carried out using the UAV. A magnetic field gradient map is plotted based on the aeromagnetic survey results. Zones of fault disturbances in the earth's crust are mapped based on zones of presence of the magnetic field gradient. Heat imaging results are used to determine areas of the earth’s surface with daytime temperature values above zero degrees Celsius and said areas are mapped on the magnetic field gradient. Then, electrical exploration is carried out by the method of shallow soundings by formation of the field in the near zone. After preliminary integrated processing of the recorded data, inversion of data obtained by shallow probing by setting the field in the near zone is carried out. Geologic-geoelectric model of the top part of the section of the earth’s crust is constructed and zones of low resistivity are identified. Zone of a geothermal underground water deposit is determined from a combination of the zone with a magnetic field gradient, the zone of the earth's surface with day-time temperature above zero degrees Celsius and the zone of low resistivity.

EFFECT: high accuracy of determining thermal water deposits.
