EXPERIENCE OF MOBILE GEOPHYSICAL TECHNOLOGIES APPLICATION DURING HYDROCARBON ACCUMULATIONS PROSPECTING AND EXPLORATION IN THE COLLECTORS OF NON-TRADITIONAL TYPE

The results of experimental application of frequency-resonance method of the remote sensing (RS) data processing and interpretation and geoelectric methods of forming short-pulsed electromagnetic field (FSPEF) and vertical electricresonance sounding (VERS) for the hydrocarbon (HC) accumulations prospecting in unconventional reservoirs (shale, and coal-bearing crystalline rocks, tight sandstones, etc.) are analyzed. It is shown that the method of remote sensing data processing allow to detect and map operatively the anomalies of «reservoir of gas (oil)» type in collectors of various types. These anomalies may be connected with «sweet spots» areas, within which there is a high likelihood of industrial inflow of hydrocarbon receiving. The anomalies of «reservoir of gas (oil)» type can also be detected and mapped by the areal FSPEF method survey. The bedding depths and thicknesses of the anomalous polarized layers (APL) of «gas (oil)» type are determined by VERS sounding. Practical application of the mobile technologies at different stages of hydrocarbon accumulations prospecting in various types reservoirs will accelerate and optimize the exploration process in general and significantly reduce the number of prospecting, exploration and production wells. 

ГЕОДИНАМІКА

The mobile geophysical technology include a special method of the remote sensing data processing and interpreting, aerial mapping method of the forming short-pulsed electromagnetic field (FSPEF), method of vertical electric-resonance sounding (VERS). Inclusion of such technologies in traditional complex of exploration geological-geophysical methods will promote both minimization of the financial expenses on the oil-and-gas exploration problems solving, and essential reduction of time for their practical realization.

ГЕОДИНАМІКА

The results of experimental approbation of geoelectric methods of forming short-pulsed electromagnetic field (FSPEF) vertical electric-resonance sounding (VERS) and the technology of satellite data processing and interpretation for the "direct" prospecting the ore minerals and water-bearing reservoirs are analyzed.

ГЕОДИНАМІКА

The results of practical application of geoelectric methods of forming short-pulsed electromagnetic field (FSPEF) and vertical electric-resonance sounding (VERS), as well as georadar soundings on destroyed by landslide area of road are given. It is shown, that the presence of the zone with raised filtering of ground waters is the main reason of roadway erosion and landslide formation. The finding and mapping of water flow and area of the raised soil moistening can be realized operatively by complex of mobile geophysical methods.
