Summary: A hybrid fracture characterization method was proposed to accurately model carbonate reservoirs in the South China Sea, utilizing traditional dual-porosity/dual-permeability (DP) method for small-scale fractures and embedded discrete fracture method (EDFM) for large-scale fractures. By calculating transmissibilities among different grid mediums, the hybrid DP+EDFM model improved water cut matches and accurately predicted water breakthrough in fractured reservoirs compared to conventional DP models.

Summary: A multiscale fractured-porous medium consists of hierarchical levels of heterogeneity, and numerical simulation of fluid flow in such a medium is challenging due to the need for a very fine numerical grid. To reduce the number of numerical cells, irregular grids based on quadtree technology are suggested. Introducing a quantitative criterion allows for formalizing the procedure for building a quadtree and embedding it in the Basilisk platform.

Summary: In this work, the generalized multiscale finite element method (GMsFEM) is combined with a reduced model based on the discrete fracture model (DFM) to efficiently and accurately simulate flow in fractured porous media. The GMsFEM represents fracture effects on a coarse grid using multiscale basis functions constructed from local spectral problems. The proposed reduction technique, which considers permeability in both fracture and matrix domain, has significant impact on solving large and complex systems resulting from modeling flow in fractured porous media.

Summary: This article focuses on the coupled system of equations describing flow in fractured porous media and employs multicontinuum and multiscale approaches. The use of multicontinuum models leads to a high number of iterations in solving the resulting linear system of equations due to the significant difference in permeability of each continuum. The presented decoupling technique separates the equations for each continuum, allowing for separate and more efficient solutions, based on the additive representation of the operator with semi-implicit approximation by time.

Summary: A smoothed embedded finite-volume modeling method is proposed for faulted and fractured heterogeneous poroelastic media. This method achieves coupling between fault slip mechanics, deformation mechanics, and fluid flow equations to ensure stability and consistency of simulation results. The method also addresses the challenge of oscillatory stress fields at faults through a smoothed embedded strategy. The sEFVM provides locally conservative mass flux and stress fields on a staggered grid, showing promise for field-scale relevant simulation of induced seismicity.

Summary: We present a scalable collocated Finite Volume Method (FVM) for simulating induced seismicity due to pore pressure changes. The method employs a fully-implicit fully-coupled description of flow, elastic deformation, and contact mechanics, resulting in a discrete system on a flexible unstructured mesh. The cell-centered collocated scheme allows for easy integration of different physical equations, and a generic multi-point flux approximation is formulated to handle heterogeneity and cross-derivative terms. The method is found to be accurate and efficient, providing a promising framework for simulating induced seismicity in various geoscientific applications.

The method uses the projection-based embedded discrete fracture model (pEDFM) to model fractures with varying conductivities. The ADM method allows mapping of the fine-scale system to a discrete domain with an adaptive grid resolution, improving computational efficiency by providing accurate solutions with only a fraction of fine-scale grids.

Summary: Underground Hydrogen Storage (UHS) is an emerging large-scale energy storage technology. Researchers investigate its feasibility and performance using numerical simulations, but existing studies may not reliably quantify the feasibility of potential storage projects due to the lack of accurate relative permeability models. This study examines how experimentally measured hydrogen-brine relative permeability hysteresis affects the performance of UHS projects through numerical reservoir simulations.
