... intrinsic properties. Marcellus shale gas, Marcellus shale condensate, and Bakken shale oil are selected as three types of shale fluids. A gradually increased CO 2 composition in fluid systems accounts for the variable amount of CO 2 during gas injection for EOR/EGR. For water-sensitive shale reservoir...

Four injection points perpendicular to the wellbore were used to simulate injection through multiple perforations, in addition to single point injection scenarios. Equilibrium dune height...

The utility of the selected set of metrics is demonstrated with data obtained from CO 2 -EOR activities in depleted oilfields of the Midwest Regional Carbon Sequestration Partnership (MRCSP...

The model used in the simulation work is calibrated with our enhanced condensate recovery experimental data which shows that huff-n...

... by forced injection of oil (i.e., achieving the same oil saturations for both processes). Permeability to a clean mineral oil (Soltrol 130) was higher than for Bakken oil—apparently because of deposition of wax/asphaltenes/particulates on the core faces when injecting Bakken oil. Permeability to oil...
