Simulation of Multiphase Flow in Subsurface Porous Media for Low-Carbon Energy Systems addresses the urgent need for pore-scale rigor in energy-transition workflows. As CO? and H? injection, groundwater management, contaminant remediation, and geothermal operations expand, decision-quality predictions hinge on resolving interfacial physics, wettability, capillarity, and transport in complex rock microstructures. This reference equips researchers and practicing engineers to interpret, calibrate, and upscale pore-scale phenomena into reliable macroscopic parameters that constrain reservoir simulation and risk assessment for low-carbon deployments. Contents integrate foundational theory with a method-centered architecture. Digital rock reconstruction introduces multiscale, hybrid, and deep-learning approaches for realistic pore geometries. Multiphase flow theory consolidates interfacial tension, wettability, capillary pressure, nanoscale transport, and extended governing equations. Dedicated chapters cover six leading techniques: molecular dynamics for kerogen nanopores and H?/water transport; lattice Boltzmann color-gradient and Shan-Chen models for methane-water and CO?-water dynamics; pore-network modeling with thin-film physics across Berea and tight sandstones; and CFD-based volume-of-fluid, level-set, and phase-field formulations with explicit numerical schemes and boundary conditions. Each chapter shares a consistent scaffold-principles, algorithms, and reproducible case studies-supported by color figures, equations, and data to enable independent use. Simulation of Multiphase Flow in Subsurface Porous Media for Low-Carbon Energy Systems empowers end users to select appropriate methods, avoid modeling pitfalls, and generate actionable outputs such as relative permeability, entry pressures, and displacement efficiencies. Readers gain transferable workflows, benchmarking insight, and transparent assumptions to de-risk pore- to core-scale upscaling for CO?/H? storage, waterflood optimization, and reactive environmental processes. Ancillary materials include MD code and simulation videos, enhancing comprehension and accelerating adoption in research and practice.Synthesizes six pore-scale multiphase simulation methods across subsurface porous media for low-carbon applicationsExplains strengths, assumptions, and limitations to guide appropriate method selectionDemonstrates reproducible workflows with case studies, flowcharts, and visual abstractsQuantifies key outputs such as relative permeability and capillary pressure from pore-scale modelsSupports CO?/H? storage analysis through MD, LBM, PNM, and CFD exemplars

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.
