Application of passive microseismic surveys is a possible solution both for geologic exploration of hydrocarbon deposits and for a number of technological problems occurring when developing oilfields.

Terravox technology allows survey of hydrocarbons under the salt domes, at great depths or in permafrost conditions. It makes it possible to see the location of fluid migration channels, unlike traditional geophysical technologies.

Production of oil and gas directly from the fluid migration channels may significantly increase the profitability of the field due to the initial reduction of wells with low debit and wells with short operating time.
