Gas-condensate flow is a critical process in the near-well region where well production efficiency strongly affected by of condensate dropout. Pore-scale simulations have provided an understanding underlying processes such as snap-off and effect interplay between viscous capillary forces on gas-condensate its induced blockage within pore spaces. Among various modeling approaches used to explore these phenomena, pore-network modeling, due computational ability simulate relatively large sample sizes, has appealed researchers. This article presents review development models flow, particularly near wellbore regions. contribution reviews pore-scale mechanisms that should be included simulating together with involved peculiarities pertinent efforts. After brief different scale studies their differences, advantages, disadvantages, focuses application recent studies. The employed methodologies, highlights, limitations each network study are examined critically discussed. addresses pore-space evolution, mechanisms, transport parameters. formulations entry pressure geometries, corresponding conductance terms, criteria, conditions for creation bridging structures presented. Additionally, three major gas condensation, namely quasi-static, dynamic methods compositional presented main governing equations using tables. Finally, significance including challenges similarities differences among provided.

Abstract Proton exchange membrane fuel cells, consuming hydrogen and oxygen to generate clean electricity water, suffer acute liquid water challenges. Accurate modelling is inherently challenging due the multi-phase, multi-component, reactive dynamics within multi-scale, multi-layered porous media. In addition, currently inadequate imaging capabilities are limiting simulations small areas (<1 mm 2 ) or simplified architectures. Herein, an advancement in achieved using X-ray micro-computed tomography, deep learned super-resolution, multi-label segmentation, direct multi-phase simulation. The resulting image most resolved domain (16 with 700 nm voxel resolution) largest flow simulation of a cell. This generalisable approach unveils multi-scale clustering transport mechanisms over large dry flooded gas diffusion layer fields, paving way for next generation proton cells optimised structures wettabilities.

Abstract The permeability of complex porous materials is interest to many engineering disciplines. This quantity can be obtained via direct flow simulation, which provides the most accurate results, but very computationally expensive. In particular, simulation convergence time scales poorly as domains become less or more heterogeneous. Semi-analytical models that rely on averaged structural properties (i.e., porosity and tortuosity) have been proposed, these features only partly summarize domain, resulting in limited applicability. On other hand, data-driven machine learning approaches shown great promise for building general by virtue accounting spatial arrangement domains’ solid boundaries. However, prior convolutional neural network (ConvNet) literature concerning 2D image recognition problems do not scale well large 3D required obtain a representative elementary volume (REV). As such, work focused homogeneous samples, where small REV entails global nature fluid could mostly neglected, accordingly, memory bottleneck addressing with ConvNets was side-stepped. Therefore, important geometries such fractures vuggy modeled properly. this work, we address limitation multiscale deep model able learn from media data. By using coupled set networks view domain different scales, enable evaluation ( $$>512^3$$ > 512 3 ) images approximately one second single graphics processing unit. architecture opens up possibility modeling sizes would feasible traditional tools desktop computer. We validate our method laminar case samples fractures. result viewing entire at once, perform prediction exhibiting degree heterogeneity. expect methodology applicable transport play central role.
