Identification of small-sized oil and gas deposits in the Pannonian Basin according to seismic data

Abstract

The article presents the results of the practical application of an integrated approach to the study of small-sized oil and gas deposits in the interval of terrigenous deposits of the lower Pontus of the southeastern part of the Pannonian Basin using 3D seismic survey. Some geomorphological features of the structure of the pre-Neogene basement of the studied area of the Pannonian Basin of the Republic of Serbia are shown, the relationship between the position of local basement ledges and the localization of new oil and gas deposits in the overlying horizons is analyzed.Based on the work carried out, a number of signs and features of the seismic material were identified, thanks to which the location of promising structures and associated hydrocarbon deposits was substantiated and coordinates for drilling new wells were proposed. The subsequent implementation of the completed drilling recommendations was confirmed by the results of testing and discoveries of new oil deposits at the Kikinda North-West field.The discovered deposits of oil and gas at the Kikinda North-West field are associated with the "root" structures of the basement, areas of through faults and subvertical local seismic anomalies. The presented results indicate the need for further comprehensive analysis of 3D seismic survey, drilling data, core studies, well logging, well testing results in order to search for and discover new hydrocarbon deposits based on the identified patterns and approaches.
