JSC “Ukrnafta” is the main oil producing company which carries out explorative drilling in the Dnipro-Donetsk’s and PreCarpathian basins. The decrease in number of seismic studies negatively affects discovery of new potential hydrocarbon bearing structures. Reliability and productivity of seismic surveys influences productivity of explorative drillings. The article analyzes the results of seismic surveys, data from case studies and geochemical surveys to predict the oil and gas prospective areas in the Dnipro-Donetsk basin, as well as their complexation. It is shown that need to use alternative methods of exploration has objectively been increasing, in particular – use of remote methods for determining the presence of hydrocarbons (using space images). To create predictive geological structural models based on a selected set of studies are widely used modern software products for reserves and resources estimation with statistical probabilistic approaches and associated risk computation functionalities. Comprehensive study of results carried out in previous years, utilization of modern methods and software for data analysis enables to define directions of geological exploration works for the following years in order to raise its efficiency and strengthen the reserves base.
