Abstract
Summary Bazhenov formation characteristic are presented in the article, unconventional reserves without hard skeleton are characterized. Fluid filtration isn’t described by Darcy’s law but influence of rock pressure due to semi-closed drainage area of collector, which in the beginning is very similar to filtration in bounded reservoir going over to filtration in limitless reservoir, at the same time drainage area can’t be bounded or limitless. The connection between the productivity of wells and the predominance of microlayer differences in which the lenticular accumulations of organic matter are concentrated has also been revealed. When the pressure decreases, a mature organic matter is subject to cracking in the reservoir conditions of the subsoil with the formation of liquid and gaseous hydrocarbons, which is reflected in the graphs “accumulated selection-reservoir pressure” and “time-flow rates of wells”. This should be taken into account when developing deposits of the Bazhenov formation and correctly set the mode for each well
