Abstract
The current stage of development of the oil industry of Kazakhstan is characterized by its entry into the stage of declining production. Many large deposits are characterized by a rapid increase in product wetting. An unfavorable geological and technological structure of oil reserves has been formed at the oilfield, where the share of traditional (technologically developed) reserves is only 35%. At the same time, the share of hard-to-extract oil reserves (low-permeable layers, residual reserves, deeply loaded horizons, high-viscosity oil, gas subsurface areas) is 2/3 or 65%. Based on the estimates given in this paper, it is proposed to consider the development of low- permeable layers and residual oil resources as priority areas for the development of hard-toextract oil reserves. Their successful development will ensure the effective development of about half of the industrial oil reserves. Increasing the efficiency of development of low-permeable layers will attract several billion tons of industrial oil reserves for development.
