PROSPECTS HYDROCARBON PRODUCTION IN THE SOUTHWESTERN PART OF THE ODESSA-REGION UKRAINE BLACK SEA NORTHERN

Abstract

Regions of Ukraine, including the Ukrainian Black Sea, have a number of fields with sufficiently large reserves of hydrocarbons that are available for development in a relatively short time and acceptable in terms of the likely costs and cost-effectiveness. The aim of the study is to establish the characteristics of raw hydrocarbon deposits forming the southwest part of the Odessa-region of Ukraine and determine the prospects of their acquisition. Objectives: 1. Analysis of geological and structural position of the Northern Black Sea region; 2. Evaluation of these data on proven reserves of oil and gas in the Odessa-region, Ukraine. Currently known stratigraphic range of oil and gas in the region include complex Neogene rocks (Sarmatian) and Paleozoic (Upper and Middle Devonian). The most complete information about the geological context of the sedimentary strata in the Odesa-region obtained from the drilling of deep wells located in different structural-tectonic zones. Among the geological prerequisites for determining attribution of certain areas of the Odessa-region to highly promising in regard to search for medium and large deposits of oil and gas, are considered the presence of a strong (up to 8 km) thickness of sedimentary formations favorable combination of geological section of rocks of different lithology and producing, accumulating and screening systems and installation of industrial oil-bearing Devonian sediments. The south-western part of the Odessa-region stands out as highly promising in respect of oil and gas within Prydobrudzkoyi area (Kisslinska and Izmail structure (4.5 billion m3 of natural gas)). Preferential development of hydrocarbon deposits in selected areas in the southwestern part of the Odessa-region due to the relatively low cost and short time (2 years) compared with other areas to ensure their own energy industrial-economic complex of Ukraine.
