Immiscible carbon dioxide (CO2) injection is an enhanced oil recovery (EOR) used to increase oil recovery from heavy oil reservoirs. This method has many advantages including the ability of the CO2 to interact with the crude oil and reduce its viscosity to mobilize the crude oil by increasing its mobility. Understanding the conditions at which immiscible CO2 injection can be injected into oil reservoirs and how it can interact with the crude oil to mobilize it is extremely important in optimizing this EOR process and also to help increase the overall effectiveness in both oil recovery and CO2 storage. This research performs a data analysis on the laboratory studies conducted using immiscible CO2 injection using more than 1000 experimental data points. The research then develops a screening criterion based on the data analysis developed in order to be able to function as a guideline to the application of immiscible CO2 injection in laboratory studies. The histograms developed include crude oil properties, reservoir thermodynamic conditions, injected fluid conditions, and CO2-Oil interactions. The data analysis was performed on all core and porous media type.
