Paper presented at the SPE Improved Oil Recovery Conference, April 25–29, 2022
Paper Number: SPE-209420-MS
... Abstract Hysteresis of transport properties like relative permeability ( K r ) can lead to computational problems and inaccuracies for various applications including CO 2 sequestration and chemical enhanced oil recovery (EOR). Computational problems in multiphase numerical simulation include...

... 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...

... 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...

... 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...

Paper Number: SPE-200438-MS
... 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...
