| Studying the low-quality reservoir rocks of the West Siberian oil-gas basin – a topical problem of oil-gas geology | |
Current exploration works are mainly directed to the searches and exploration for fields with reservoir rocks characterizing by enhanced filtration-capacity properties. But conventional hydrocarbon resources are restricted; they are not renewable, and in the modern high level of their consumption, the depletion of them occurs very rapidly. Therefore setting up a qualitatively new problem – the study, definition and estimation of low-quality rocks (permeability of no more than 0.05 mkm2, open porosity of less than 10% in terrigene deposits and less than 5% - in carbonate rocks) – is topical at the present time. A broad lithologic series, a large stratigraphic range and the wide occurrence of low-quality reservoir rocks with already established petroleum potential in the geological sequences of the West Siberian oil-gas basin is indicative of the considerable perspectives of their development. Key words: low-porosity, low-permeability, low-quality reservoir rocks, West Siberian oil-gas basin, sedimentary cover, basement. |
