Refinement of the conceptual model and algorithms to the development of hydrocarbon deposits based on fractal ideas about the nature of their geological structure

Abstract

This study examines the productive horizon of Miocene deposits in an oil and gas field in the Pannonian Basin (Republic of Serbia). To clarify the features of the geological structure and improve the efficiency of upcoming development of new productive areas while increasing oil recovery from existing parts of the field, the authors of this paper conducted a detailed analysis and synthesis of core data, seismic work materials, testing and the dynamics of production wells. Through conducted studies, the authors detailed the geological features of the field, updated the conceptual model, and proposed additional methods for developing the identified oil and gas reservoirs. Researches also rebuilt the geological model, adjusted the placement of the project well stock and developed a set of geological and technical measures to enhance oil recovery. Furthermore, they forecasted of development indicators. The study identified features of the field’s geological structure that suggest a “mosaic” distribution of filtration and capacitive properties within the established hydrocarbon reservoirs. The localized character of the distribution of productivity and variability of field parameters that influence the success of discovery, efficiency of involvement and development of such hydrocarbon deposits confirms the fractal properties of the geological environment. In conclusion, the authors highlighted the necessity of studying and applying the fractal properties of geological objects during oil and gas exploration.
