Mechanisms of interaction of CO₂ with reservoir oil

Abstract

The article aims to examine the mechanisms of miscible and immiscible interaction of CO2 with oil in detail. The study aims to investigate the effects of these mechanisms on the physical properties of oil, recovery efficiency, and oil reservoir parameters. This will enhance our understanding of the impact of these processes on oil production and carbon management. The article takes an analytical approach to examine the processes of CO2 dissolution in oil, changes in physical properties, and mechanisms of oil displacement in the pore space. The study utilises the results of laboratory experiments on the interaction of CO2 with oil. It reveals how the miscible interaction of CO2 with oil can alter the physical properties of oil, enhancing its flowability and recovery efficiency. An analysis of immiscible interactions enables us to comprehend the mechanisms of oil displacement and optimize the process. The work is relevant to oil production and carbon management, providing data for the development of more efficient production technologies and methods.
