Abstract The research is aimed at expanding the applicability of logging tool with toroidal coils from vertical to highly deviated wells. Its electromagnetic signals are computed a three-dimensional finite-difference simulation algorithm on computing resources Siberian Supercomputer Center SB RAS, which accompanied by multi-aspect numerical analysis signals. We consider wide range geoelectric m...

Geoelectricity is a geophysical method that conducted by injecting an electric current into the earth’s interior. This study objected to map aquifer aquifers using geoelectric with Schlumberger electrode configuration consisting of 4 sounding points. The measurement results are then processed IP2WIN software which produces real resistivity as function depth. correlation between points three-dim...

Abstract We investigate the maximum expected magnitudes of geomagnetically induced currents (GICs) in Czech transmission power network. compute a model utilising Lehtinen–Pirjola method, considering plane-wave geoelectric field, and using network parameters kindly provided by operator. find that amplitudes nodes grid during Halloween storm-like event are about 15 A. For “extreme-storm” conditio...

The specific electrical resistance (electrical conductivity) of some layered sedimentary rocks the Baikal natural territory was measured by method radio impedance sounding in VLF-LF ranges electromagnetic waves. Their geoelectric sections are determined. Information about geoelectrical section (GES) can be used engineering and geological surveys Siberia-Mongolia-China gas pipeline route, as wel...
