Discrete formation of “shale” gas reservoirs in exfiltrate catagenesis
The dynamics of “shale” gas reservoirs formation in the processes of exfiltration catagenesis was showed. Several types of hydrocarbon reservoirs were distinguished. These reservoirs in different parts of clayey complexes were forming not simultaneously and differ by individual way of structure and fluid regime evolution. In connection with latter it is necessary to use the individual approach to oil-gas extracting works in each specific situation.
