reservoir rocks

The study of geodynamic processes, the distribution of reservoir pressures and the properties of deep rocks in Ukraine's oil and gas basins, is crucial for enhancing geological exploration, predicting hydrocarbon accumulation, and assessing production methods. This is an important and timely issue in the field today. Analysis of geological and geophysical studies, deep drilling, laboratory studies of core and sludge, as well as experiments to examine the physical properties of reservoir rocks, form the optimal approach to address this issue.

Results of field geophysical investigations and data of litological-petrophysical studies of core samples have been analyzed. A complex of petrophysical and geophysical indicators of rocks of lithological traps in the Lower Carboniferous deposits of the Dnieper-Donets Depression has been developed. It was concluded that the best reservoir rock properties are characteristic for the channel and bar sand bodies, represented with anisomerous quartz sandstones with carbonated-clayed and quartz-clayed-carbonated cement.
