Abstract
This paper analyzes the impact of gas on the properties of reservoir water from various reservoir horizons in oil fields in the Republic of Tatarstan. The study utilized both original reservoir water samples and treated water samples that were prepared with a gas agent. Authors employed pressure-volume-temperature (PVT) analysis methods throughout the research. Authors collected subsurface samples of reservoir fluid from the water-bearing horizon A1 of the Devonian system and horizon B of the Carboniferous system.
The experimental results showed that the gas agent has a relatively high solubility in the reservoir water, which increases with reservoir pressure until a certain limit is reached. Additionally, it was confirmed that the solubility of the gas agent in reservoir water is also affected by the salinity of the water.
