“…This method greatly decreased the calculation time, thereby making multiphase flow in 3D space computable. Related studies can be found in (Guo et al, 2018a(Guo et al, , 2018b(Guo et al, , 2019Mehmani and Tchelepi, 2018;Soulaine et al, 2018;Wong et al, 2019). The method can potentially calculate spontaneous imbibition in the future.…”

Spontaneous imbibition in shale is commonly observed during and after hydraulic fracturing. This mechanism greatly influences hydrocarbon recovery in shale plays, therefore attracting increasing attention from researchers. The number of related publications is increasing. In this review, we summarize the recent advances in shale spontaneous imbibition from three aspects, namely, conventional spontaneous imbibition models, common experimental methods, and key mechanisms that need to be focused on. The major influencing factors on the shale imbibition process are discussed, and promising future works are presented on the basis of the merits and demerits of the recent studies. This study discusses the mechanisms of shale-liquid interaction, the complexity of multiphase flow in shale plays, and highlights the achievements and challenges in shale imbibition research.

“…An important application of the DBS‐based model is to study the flow and reactive transport processes in complex pore structures obtained from

‐CT. Under the framework of the micro‐continuum approach, the model was widely used to study shale gas transport (Guo et al, 2018) and in porosity/permeability analyses (Soulaine et al, 2016) in realistic situation. Besides, based on the same framework, Carrillo and Bourg (2019) developed a Darcy–Brinkman–Biot (DBB) based HMM to analyze the hydrologic and mechanical coupling of soft porous media (e.g., clay and elastic membranes).…”

Recent progress in multi‐scale modeling and simulation of flow and solute transport in porous media

The heterogeneity and multi‐scale characteristics of porous media (such as soil aquifers) bring a series of uncertainties in studying flow and solute transport. In particular, the mathematical representation of these physical processes at different temporal and spatial scales, that is, the constitutive equations and parameters, is largely varied, which creates grand challenges in multi‐scale modeling and numerical simulation of flow and solute transport in porous media. In recent years, we acknowledge that at‐scale models and simulations have been greatly progressed, which means that at each individual scale, the transport phenomena, numerical methods, and solvers have been developed and utilized at different levels. However, the long‐standing problem, scale coupling between the pore‐ and Darcy‐scale in porous media, has not been well resolved. In this review, we present an overview and classification of the current multi‐scale models, aiming to understand small‐scale flow and solute transport processes when/where needed in a larger system. This review begins with a brief introduction of the pore‐ and Darcy‐scale theories. Two groups of multi‐scale models that are state‐of‐the‐art, based on the Darcy–Brinkman–Stokes equation and the domain decomposition method, respectively, are explained in the context of research progress in model theory, numerical algorithms, and applications. Future research perspectives and challenges are also discussed from both modeling and application points of view. This review is expected to provide a fundamental understanding of flow and solute transport in porous media and concept of developing multi‐scale models to bridge the gaps between processes in adjacent scales.

“…Notably, the very same CFD software was also used in the reference study [41] in order to characterize real rocks. Furthermore, OpenFOAM is also used in several recent studies dealing with real porous media [23,25], and also for other physical configurations such as two-phase flows [42], particle transport [ l l], inertial flows [36], or compressible flows [24].…”
