Hydrocarbon compounds and plausible mechanism of gas generation in “shale” gas prospective silurian deposits of Lviv paleozoic depression

Purpose. Investigations of composition of gas within closed porosity (fluid inclusions and closed pores in rocks) of prospective gas-bearing Silurian graptolitic argillites of Lviv Paleozoic depression and ground of plausible mechanism and dynamics of gas generation during “shale” gas formation in productive strata of black-shale formations of the region. Methodology. The composition of volatile fluid inclusions and closed pores of rocks, and their relative gas saturation and water saturation were determined by mass spectrometric chemical method.
