Abstract
The report presents the analysis of petrophysical properties and the estimation of void space structure based on the results of petrophysical studies for rock samples of the moscovian stage, middle Carboniferous, Western Shebelynska area (depth interval 4929–5380 m). There is made a statistical analysis and samples of sandstones discrimination based on the results of porosity, permeability, electrical and acoustic properties examination. Moreover, there are examined correlations between the studied parameters. The present study uses the state of the art methodology for void space structure examination. The latter allows to invert petroacoustic data into the void space structure. There are made calculations of the presence of various types of pores in the overall porosity. Reservoir rocks being determined during petrophysical analysis, are claimed to belong principally to fracture-granular type.
