Abstract

The complex of geological and geophysical studies for predicting reservoir rocks of oil and gas fields has been suggested. For this purpose, structure-paleogeomorphological, lithofacial, borehole geophysical and seismic studies related to a particular algorithm of work are used. Practical application of complex of mentioned methods has been demonstrated on the example of Semyrenkivskyi oil and gas condensate deposits of Dnieper-Donets basin. The prediction results of reservoir rocks have been demonstrated. They are supposed to be used for selection the optimal allocation of operation, test and prospecting boreholes.

Abstract

The Eastern oil- and gas-bearing region of Ukraine is the youngest one as regards the discovery of commercial hydrocarbon deposits and the greatest one in terms of volume of explored reserves and hypothetical resources. It is confined to the Dnieper-Donets Depression. There were more then 240 hydrocarbon deposits discovered here. We have analyses the geochemical composition of oil and condensate for 3 main structural-tectonic elements of the region: northern, southern edges and depression, as well as we have carried out comparative analysis of the composition of natural hydrocarbons within the limits of the region. The analysis of the peculiarities of geological structure and oil and gas presence together with available geochemical data has made it possible to come to a conclusion about that the formation of oil and gas deposits in the Eastern oil- and gas-bearing region was caused both by lateral and vertical migration of hydrocarbons.

Abstract

From the seismic data the extent of the perspective on oil and gas of the Mesozoic sediments is considered on a south-west of the Western region of Ukraine. The boundary of сretacions formations in and character Precarpation of Mesozoic paleorelief are described under of thrust the Carpathians to the Uzhotsky tectonical deformations zone as south-western boundary of the East European Craton.
