Identification and main petrophysical parameters of a compacted reservoir on the example of the Dnipro-Donets Depression

The issue of Ukraine’s energy security and diversification of exploration directions is of extremely great importance today. At the same time, low-permeability, low-porosity rocks make up a significant part of Ukraine’s productive complexes of the oil and gas regions. The research is focused on the deposits of the Dnieper-Donets Depression as Ukraine’s main oil and gas region. An analysis of the change in the threshold value of porosity depending on the depth of occurrence for almost all productive complexes of the Dnieper-Donets Depression was carried out. The threshold values of the main petrophysical parameters for compacted reservoirs are given.
