Middle Frasnian-Visean natural reservoirs of hydrocarbons in Timan-Pechora oil and gas province
Relationships between hydrocarbon pools of multilayer fields are analyzed from the three layer reservoir theory point of view. Reservoirs of different stratigraphic volume are revealed and mapped, such as Domanic-Lower Zadonian, Domanic-Ust-Pechorian, Domanic-Visean, Upper Frasnian-Visean subregional, Domanic-Vetlasyanian, Domanic-LowerYeletsian zonal and some local ones inside them.
