Logistics distribution vehicle planning is an important issue in logistics transportation activities, and it also a research hotspot theoretical circles at home abroad. At present, many studies have focused on establishing models optimizing different environments achieved rich results. As part of production process, the efficiency very to whole process. Especially for emergency logistics, every...

Abstract Surfactants formulated into oil-based mud can adsorb to pore surfaces causing changes in rock wettability, which are widely believed impair formation permeability when invades the near-wellbore region. In present study, effects of with Versawet and Versacoat surfactants, on petrophysical properties wettability drilling cutting samples from sandstone reservoirs were investigated through...

Abstract Mass transfer rates at liquid–liquid interfaces are relevant for a broad range of processes in natural and technical systems. The objective this study was to characterize quantify convective flow along the interface between water nonaqueous‐phase liquids (NAPLs). Three NAPLs with different solubility were used: 1‐heptanol, 1‐octanol, 1‐nonanol. visualized recorded micromodel setup fluo...

An aqueous suspension of silica nanoparticles or nanofluid can alter the wettability surfaces, specifically by making them hydrophilic and oil-repellent under water. Wettability alteration nanofluids has important technological applications, including for enhanced oil recovery heat transfer processes. A common way to characterize is measuring contact angles an droplet with without nanoparticles...

This paper aims at an accurate and efficient computation of effective quantities, e.g. the homogenized coefficients for approximating solutions to partial differential equations with oscillatory coefficients. Typical multiscale methods are based on a micro–macro-coupling, where macromodel describes coarse scale behavior, micromodel is solved only locally upscale which missing in macromodel. The...

We present two novel Volume-of-Solid (VoS) formulations for micro-continuum simulation of mineral dissolution at the pore-scale. The traditional VoS formulation (VoS- ψ ) uses a diffuse interface localization function to ensure stability and limit diffusion reactive surface. main limitation this is that accuracy strongly dependent on choice function. Our first improved (iVoS) divergence flux lo...

Naturally fractured reservoirs are one of the hydrocarbon resources where application foam flooding is particularly recommended, as can divert flow displacing fluid from high-permeability regions (fracture networks) to low-permeability (rock matrix blocks). However, its in heavy oil challenging and results inadequate sweep efficiencies. The current practice (including polymer enhanced flooding,...
