Petrophysical properties of the Lower Permian limestones of the Glinsko-Solokhivsky gas-and oil-bearing region of the Dnieper-Donets depression

Summary The main objective of this article is to study petrophysical parameters of Lower Permian carbonate rocks of western part of the Glinsko-Solokhivsky gas and oil region of the Dnieper-Donets depression (DDD) in normal (atmospheric) and modeling (reservoir) conditions. Lower Permian carbonate rocks (that are promising in hydrocarbon content) are widespread within the western part of the Glinsko-Solokhivsky gas and oil region of the DDD. In the Research laboratory of theoretical and applied geophysics of the Institute of Geology comprehensive petrophysical study was carried out, which included determination of: density of rocks; their resistivity; apparent and effective porosity; structure of capillary space; velocity of elastic waves in atmospheric and reservoir conditions. Also, petrophysical research took place. The comprehensive analysis of petrophysical data has been resulted in a set of correlation ratios between reservoir, electric and elastic parameters of studied limestones in atmospheric and reservoir conditions.
