.... Durlofsky (1991) applied periodic boundary conditions for coarsened cells' permeability tensors, ensuring consistent upscaled permeability fields. However, these conditions may not apply to highly heterogeneous fields. Durlofsky et al. (1994) proposed an alternative method for non-uniform coarsening...

... at different reservoir and operational conditions. We first analyze a stratified layer model to understand the basic mechanisms of scale-dependency of dispersion and the significance of reservoir heterogeneity on fluid mixing. To consider more realistic reservoir heterogeneity, a two-dimensional stochastic...

... Abstract Assessment of subsurface heterogeneity in carbonate reservoirs is critical for optimizing core sampling locations for reliable calibration of core- and reservoir-scale petrophysical models. The objectives of this paper are (a) extracting NMR-based pore-size distribution (PSD...

... injectivity loss. This study investigates the impacts of capillary pressure and permeability heterogeneity on the formation of hydrates during CO 2 storage in depleted gas reservoirs. A compositional thermal reservoir simulator is used to model the fluid and heat flow of CO 2 in methane and water-saturated...

... of solvent chambers in reservoirs. However, reservoir heterogeneity stemming from shale barriers plays a detrimental role in the conformance of solvent chamber development and oil production rate. In this work, we develop a novel recurrent neural network (RNN)-based framework with the capability...

... behavior of heterogeneous reservoir is still missing to push forward the application of time-consuming coupled reservoir-geomechanical simulation. Here, we focus on the impact of lithological heterogeneity on the shear strength and stress-strain behavior and propose a deep learning-based upscaling...

... Abstract The main challenge of modeling the glacial sandstone deposits is capturing the property pattern in the reservoir, because of the abrupt changes from one depositional environment to another. This reservoir heterogeneity impacts the infill well planning and production performance...

..., the heterogeneity in porosity, permeability, and capillary pressure curves can be considered using the Leverett j-function. To further consider pressure-dependent IFT and contact angles ( θ ) and their influence on capillary pressures, the keyword ‘SRFTNG’ in CMG-GEM was further adapted here to scale capillary...

This study uses three-dimensional digital image correlation (3D-DIC) to examine damage and deformation in HDR samples. HDR samples from the DOE Utah FORGE project's...

... Abstract Pore structure heterogeneity is present in reservoir rocks at multiple length scales, which makes it a challenge to optimally assess and integrate into digital rock and pore-scale models, especially for complex reservoir rocks. The fractal nature of reservoir rocks causes variation...

Results suggest that large-scale heterogeneity dispersive transport is the dominant factor affecting the hydrogen storage efficiency when compared to molecular diffusion, core-scale dispersion and, depending...

... Abstract The identification of reservoir heterogeneity is normally attempted by constructing profiles of conventional well-test derivatives with transient-pressure data. Second-order derivatives are more sensitive than the first-order derivatives in the respective profiles with heterogeneity...
