Since 2021, INTERRASCAN LLC has been developing and implementing unique and innovative geophysical technologies based on the Russian science breakthroughs. The Company's experts have over a decade of successful experience in developing high-resolution geoelectric exploration techniques and tailor-made software.

Deep High-Resolution Pulse Geoelectric Exploration (DHRPGE) – is a new stage in developing non-destructive geophysical express methods allowing for high-detailed geological strata exploration at up to 400 m depths, as well as for high-resolution surveys at depths of up to 50 m, crucial for solving engineering geology tasks.

DHRPGE technology has a long-term success story in geological exploration. Its application ensures significant increase in the speed and efficiency of engineering and geological surveys and lets prevent and/or minimize accidents and disasters caused by hazardous geological phenomena and man-made impacts on the subsurface.

The DHRPGE technique is highly efficient in surveys of complex, flooded and saline soils and permafrost exploration, it works from any surface (fresh water, ice, snow, swamp, etc.) in any season.



DHRPGE is a contactless pulsed geoelectrical exploration technology based on a modification of GPR that uses an ultra-wideband electromagnetic signal in the range of 1-1000 MHz for sounding soils, and antennas in the form of resistive-loaded dipoles. Depending on the tasks and the required depth, antennas of various lengths are used.

The technology is based on registration of reflected electromagnetic waves from subsurface with different geoelectric parameters. These parameters are closely correlated with the physical properties of geological elements: density, porosity, moisture content, and others. The main information about geological structures is the amplitude of the pulse reflected from the interface, its shape, polarity and the time interval between the generation of the pulse by the transmitter and the registration by the receiver of signals reflected from the sections of geological media. During exploration, the GPR moves along the profile between physical measurement points with a specified step or with continuous shooting along the horizon. Modern GNSS equipment is used to bring the profiles to the terrain.

The signal source generator has the ability to adjust the power for surveys at different depths and generates a nanosecond pulse (unipolar pulse without high-frequency filling) with a steep leading edge. The steep leading edge of the pulse and its large amplitude determine the high resolution of the technology, the large depth of sounding, and the ability to work in low-resistance environments – like wet soils, clays and loams.

The result of the exploration is a geoelectric section (radargram), translated into a depth scale. The translation is carried out based on the results of field calibration and reference to existing geological wells, archival data of engineering and geological surveys. The results of impulse electrical exploration can be compared with the results of seismic exploration and classical geoelectrical exploration.
