Alexander Gilmanov, Associate Professor in the Department of Physical Processes and Systems Modeling at the Faculty of Natural Sciences of Tyumen State University, recently stated that his team, through hydrodynamic modeling, discovered that in gas-oil or gas-condensate reservoirs located between a gas cap and an aquifer, prioritizing the development of a small amount of oil can significantly improve recovery rates, offering advantages over traditional simultaneous development of the gas cap and oil rim. The study indicates that when the gas-oil interface is close to the water-oil interface, gas and oil production operations should be initiated nearly simultaneously to optimize production efficiency.

The research team further identified an optimal oil flow threshold in reservoir development. Exceeding this threshold increases the pressure differential between the gas cap and oil rim in the well area, accelerating gas coning and reducing recovery rates. This critical value is twice as low as results from traditional approximate analytical methods, providing more precise parameters for engineering practice.

Additionally, the study revealed the impact of reservoir type on key recovery parameters in oil and gas condensate reservoirs. Analysis shows that horizontal permeability is more sensitive to gas breakthrough effects than vertical permeability, particularly under specific reservoir conditions where changes in horizontal permeability have a more significant impact on production well performance.

As an innovation, physicists introduced a dimensionless similarity complex into the classical hydrodynamic model of fluid filtration in porous media for the first time, simplifying simulations under complex geological conditions. To rapidly evaluate the economic viability of different development scenarios, the team plans to develop a universal tool integrating economic indicators and machine learning algorithms to optimize oil and gas reservoir development decisions

Meanwhile, archaeologists at Tyumen State University are concurrently studying Bakal culture architecture, analyzing the structural features of dwellings and hearth arrangements at the sites. The study notes that calcined traces in hearth areas provide crucial clues for reconstructing ancient lifestyles.

This series of research is conducted under Russia’s "Priority 2030" program, aiming to promote synergistic innovation in energy development and cultural heritage studies through interdisciplinary collaboration. Relevant results have been submitted to an international energy engineering journal and are planned for on-site validation in cooperation with oil and gas companies.
