Estimation of Minimum Miscibility Pressure for Flue Gas Injection Using Soft Experimentations

Advancements, Challenges, and Perspectives of Flue Gas Injection in Subsurface Formations: A Comprehensive Review

“…In simpler terms, as the concentration of CO 2 in the injected gas rises, it leads to increased swelling and reduced viscosity of the crude oil. 40 Li et al 41 explored the utilization of flue gas injection in thermal recovery processes for heavy oil. They conducted a 1D core flooding test capable of measuring temperature to analyze heat transfer and heat front progression within the reservoir rock.…”

“…Their experimental findings demonstrated that increasing the CO 2 content in the flue gas effectively reduces the MMP, leading to an improvement of oil recovery. In simpler terms, as the concentration of CO 2 in the injected gas rises, it leads to increased swelling and reduced viscosity of the crude oil …”

“…Furthermore, flue gas injection leads to an increased presence of lighter components in the oil produced from the well. 24 Oyinloye et al 40 investigated the minimum miscibility pressure (MMP) of flue gas when combined with crude oil. Their experimental findings demonstrated that increasing the CO 2 content in the flue gas effectively reduces the MMP, leading to an improvement of oil recovery.…”

Integration of Domain Knowledge and Data-Driven Modeling Evaluation Process for Predicting Minimum Miscible Pressure of CO2–Oil Systems in CCUS

“…6 At present, the main MMP methods include classic experimental methods, experience formula methods, equation of state methods, and numerical simulation methods. 7 The most popular type of experiment in experimental techniques is the slim-tube experiment. It also incorporates the interface tension disappearance method and the rising bubble apparatus.…”
