POSSIBLE MECHANISMS OF GROWTH OF UNCONVENTIONAL HYDROCARBON POOLS IN CLAY LAYERS
The discovery of commercial oil accumulations in granitoids, as well as oil and gas in clay layers considered as oil and gas mother ones gave birth to a new term, unconventional reservoir. However, active chemical and tectonic processes stimulating the growth of various-shape void spaces in such reservoirs suggest the unconventional nature of the hydrocarbon pools.
