Foam flooding is an important method used to protect oil reservoirs and increase oil
production. However, the research on foam fluid is generally focused on aqueous foam, and …

Heavy-oil reservoirs with thin-pay and bottomwater can be exploited effectively by thermal
recovery process assisted by flue gas and n-hexane. The interface properties between flue …

In the initial period of CO2 flooding, formation pressures of reservoirs do not increase
noticeably. Physical simulation experiments were designed to study this phenomenon. In the …

Pendant drop method has been used to measure the equilibrium interfacial tension and
dynamic interfacial tension of CO2/crude oil system under the simulated‐formation …

Many experimental investigations on carbonated water injection (CWI) have shown an
increase in oil recovery which CWI is defined as the process of injecting CO 2-saturated …
