Lithological features of non-traditional siliceous reservoirs of the Nizhneberezovskaja subsuite (Santonian, Campanian) are reviewed. Potential siliceous collector is represented by silicon deposits in varying degrees transformed (flasks, diatomite, tripoli radiolarites) and opoka clays. The best quality and capacity of the collectors are expected in the central and northwestern areas of the lowland, in the northeasterly direction crystallization of the flasks and deterioration of reservoir properties are observed. The most promising for the formation of hydrocarbon accumulations in siliceous reservoirs are regions with underlying gas deposits in the Cenomanian and Turonian as well as zones of anomalous heating and zones of expected generation of oil and gase in the pre-Quaternary time.
