Abstract
The main objective of the article was to look at petrophysical parameters the Cambrian rocks of the southern slope of the Lviv Paleozoic trough in normal (atmospheric) and modeling (reservoir) conditions. The studied area is one of the most promising areas for the presence of non-conventional hydrocarbon deposits (shale gas, gas of condensed rocks, etc. ) that may exceed the conventional resources. Cambrian consolidated terrigenous rocks are represented by low porosity sandstones and siltstones. In the Research laboratory of theoretical and applied geophysics of the Institute of Geology comprehensive petrophysical study was carried out, which included determination of: density of rocks; their resistivity; porosity and effective porosity; structure of capillary space; velocity of elastic waves in atmospheric and reservoir conditions. Also, petrophysical research took place. The comprehensive analysis of petrophysical data has been resulted in a set of correlations between reservoir, electric and elastic parameters of studied siltstones and sandstones in atmospheric and reservoir conditions.
