Summary: In this study, the hierarchical finite element method (Hi-FEM) is used to simulate fluid flow and heat conduction in complex geological environments. The method incorporates hierarchical basis functions and the Yeh's Galerkin model to accurately model fractured porous media, demonstrating its reliability in large-scale simulations with complex fracture networks.

Summary: This study characterizes the entrapment of asphaltene-stabilized water/brine-in-oil emulsions in microfluidic porous media by two mechanisms: adhesion and hydrodynamic bridging. Lower water fractions result in droplet adhesion to deposited asphaltenes, while erosion and bridging between droplets become more prevalent at higher water fractions. The addition of salinity weakens adhesion but leads to increased droplet size and enhanced bridging. Higher salinity also reduces interface elasticity, resulting in larger emulsions with more erosion and bridging.

Summary: This study compared the efficiency of D-limonene with other solvent-based microemulsions for removing asphaltene deposits. The results showed that all tested microemulsions had higher removal efficiency than the control formulation, with the type and amount of solvent strongly influencing the rate and amount of removal. The most effective formulations followed a pseudosecond-order desorption kinetic model, supporting a mechanism where the microemulsions solubilize the asphaltene deposits.

Summary: The study presents a set of algorithms for simulating dynamic pore-network model of immiscible two-phase flow in porous media, applicable for both drainage displacements and steady-state flow. The algorithms effectively reproduce fundamental results of transient and steady-state two-phase flow in porous media, showing the ability to replicate flow patterns like viscous fingering, capillary fingering, and stable displacement by adjusting capillary number and viscosity ratio. Additionally, the algorithms verify nonlinear rheological properties and the transition to linear Darcy behavior with increasing flow rate, as well as establish relationships between seepage velocities in two-phase flow in porous media with regular and irregular networks.

Summary: Numerical simulations were conducted to investigate asphaltene deposition induced by solvent injection, revealing the interplay of viscous fingering and deposition, as well as the impact of DME injection on oil upgrading. The dynamics of viscous fingering were found to be independent of deposition rate and governed by viscosity ratio, while grid dependency of deposition presented a computational challenge. Scaling relations were developed to address this issue and pave the way for integrating LLE data in numerical simulations of asphaltene deposition.

Summary: The study developed a multiphase simulator to predict asphaltene deposition and validated the robustness of the simulation results. It was found that using single-phase assumption under multiphase conditions led to significant errors, which could result in economic and operational burdens for the oil and gas industry.

Summary: This article investigates the Ostwald ripening of trapped bubbles in porous media, which is relevant to subsurface and manufacturing applications. Through simulations and theoretical analysis, the article reveals the evolution process of the bubble size distribution from initially non-uniform to stable equilibrium, and finds that the equilibration of bubbles in heterogeneous porous media is slower than in homogeneous media.

Summary: In situ recovery involves injecting lixiviant into ore formations to extract target metals, with establishing uniform contact between the fluid and the ore being a major challenge, especially in fractured environments. Titanium dioxide nanoparticles show potential in destabilizing asphaltene deposition, but require stabilization methods for effectiveness.

Summary: This article introduces a generalized dimensional reduced model that preserves full-tensor permeability effects in fractured reservoirs, including effects in the vertical direction. The governing equations for flow of lower-dimensional objects are obtained through vertical averaging, and a discretization framework for mixed-dimensional problems is proposed for easy adaptation of existing simulation tools. Numerical examples demonstrate the failure of existing formulations in anisotropic faulted porous media, and the convergence of the new method in both two-dimensional and three-dimensional contexts.
