... e   p h a s e . We use the state function approach to model relative permeability. Khorsandi et al. (2017) first proposed an equation-of-state to calculate the change in relative permeability for phase ( j ) as a function of five state parameters given by, State function approach...

... permeability curves simulated digitally. Porosity and relative permeability end points were also measured on preserved STACK core plugs. Minimum miscibility pressure (MMP) measurements of field separator gas and STACK crude oil was performed with a rising bubble apparatus (RBA). Finally, a huff-n-puff...

... compositional simulator to forecast gas injection improved oil recovery (IOR) in shale. We also use the updated gas saturations in the multi-scale PVT model to modify the relative permeability tables used in the compositional simulation. We predict significantly higher gas production and lower oil production...

... and predicts a smaller oil recovery than in the field. This suggests that both the nanoparticles and gas play an important role in increasing the relative permeability to oil and improving oil recovery. Results from the sensitivity study show that larger injection volumes of nanoparticles and gas result...

... Abstract Accurately modeling three-phase relative permeability remains a great challenge to reservoir engineers, in part because of a lack of experimental data to use when verifying model results. This is especially true when the fluids are changing composition, such as for miscible gas...

.... In this paper, a general equation-of-state (EoS) approach is developed for relative permeability ( k r ) based on a set of geometric state parameters: normalized Euler characteristic (connectivity) and saturation. Literature data and pore-network modeling (PNM) simulations are used to examine the functional...

... by viscous fingering. Typically, viscous fingers cannot be accurately captured with the grid sizes used in full-field simulations. To optimize and design a partially-stable polymer or water flood, it is critical to correctly upscale the laboratory-generated relative permeability curves for reservoir...

... Another unsteady-state method of measuring three-phase relative permeability is by gravity drainage. A sand pack initially saturated with water and oil is opened to the atmosphere. The water and oil are drained from the sand pack under their own gravitational gradient and are displaced by air...

However, the number of core samples analyzed in the laboratory was not sufficient to provide appropriate relative permeability and capillary pressure curves for the dynamic reservoir model ( Hetherington 1961 ). Downhole relative permeability and capillary...

... is critical since the optimum ratio is influenced by the wetting state of the rock. A WAG ratio of 1:1, which is the most popular in field applications, is not necessarily the most appropriate. Regarding flow properties, relative permeability should be evaluated under three-phase conditions and making sure...

Much of the paper explores why this result occurred. That is, was it due to the core, the oil, the saturation history, the relative permeability characteristics...

The assumption of vertical equilibrium (VE) is made, which gives maximum crossflow vertically and therefore the largest possible coning.
