Simulation of Multiphase Flow in Subsurface Porous Media for Low-Carbon Energy Systems addresses the growing need for accurate prediction of fluid transport processes in subsurface environments supporting the energy transition. As natural gas production, carbon storage, hydrogen storage, geothermal energy development, groundwater management, and environmental remediation expand globally, an understanding of pore-scale multiphase flow behavior is critical to deliver reliable reservoir characterization and performance evaluation.This reference presents six major pore-scale simulation approaches used to investigate multiphase flow in porous media, including molecular dynamics, lattice Boltzmann methods, pore network modeling, and computational fluid dynamics. It examines the fundamental physics governing wettability, capillary forces, interfacial interactions, and transport processes while comparing the capabilities, assumptions, and limitations of each method. Case studies, flowcharts, and visual summaries demonstrate practical modeling workflows and interpretation of simulation results.Simulation of Multiphase Flow in Subsurface Porous Media for Low-Carbon Energy Systems serves as a valuable reference for researchers, engineers, and graduate students working in subsurface energy and environmental systems. By linking pore-scale mechanisms to macroscopic properties such as relative permeability and capillary pressure, the book provides actionable insights for model selection, uncertainty reduction, and decision-making in low-carbon energy applications.Synthesizes six leading pore-scale simulation methods for subsurface low-carbon energy applicationsExplains method selection through comparisons of capabilities, assumptions, and limitationsDemonstrates reproducible workflows using case studies, flowcharts, and visual abstractsQuantifies relative permeability, capillary pressure, and transport characteristics from pore-scale simulationsSupports carbon storage, hydrogen storage, and geothermal energy analyses with practical examples

This book addresses the problems involved in the modelling and simulation of shale gas reservoirs at pore scale, and details recent advances in the field. It presents the construction of simulation methods, mainly using the lattice Boltzmann method (LBM), that describe sorption, flow, and transport in nanoporous shale with some case studies. This book highlights the nanoscale effects, ascribed to the large surface-to-volume ratio, on fluids occurrence and transport physics. It discusses some interesting phenomena occurs at nanoporous shale, such as absorbed water film, water condensation, sorption hysteresis, surface excess adsorption, Knudsen diffusion, surface diffusion, structural fluid density, no-slip boundary, etc.The key techniques and methods introduced in this book provide the basis for accurate prediction of gas-well productivity. The basic principles and modeling methods are also relevant to many other nanoporous applications in science and engineering.The book aims to provide a valuable reference resource for researchers and professional scientists and engineers working on shale gas development and nanoporous media research.
