Abstract

The "Sopron - X" oil field is part of the "Z-1" oil field, located on the territory of Hungary. Several wildcat wells have been drilled within it so far, and their construction was preceded by numerous geological, geophysical, geochemical and hydrodynamic tests. They are used to define the stratigraphic characteristics of the deposit, tectonic relations, petrophysical characteristics of the rocks, and physical-chemical and PVT characteristics of the deposit fluids. Hydrocarbon reserves in the reservoir are also defined. The paper presents the production characteristics of the deposit and the characteristics of the fluid inflow into the considered wells were processed. To predict the possible production of wells, an analysis system was made in the software package "PIPESIM". Data obtained by hydrodynamic measurements, as well as data on fluid characteristics, were used for the analysis. At the ''Z-1'' deposit, after the hydrodynamic measurements were carried out, the production characteristics were determined, which are of great importance when making decisions about the way and methods of deposit exploitation, production intensity, economic profitability, as well as the length of commercial profitability of the "Sopron-X" oil field and Z-1 oil deposit in general. Key words: oil, gas, oil field, hydrodynamic measurements, stocks, oil recovery factor
