A novel method to fabricate micromodels with varying depth (2.5-D) was developed, which allows more realistic investigation on flow in natural 3-D porous media.
Summary Injecting oil-in-water (O/W) emulsions stabilized with nanoparticles (NPs) or surfactants is a promising option for enhanced oil recovery (EOR) in harsh-condition reservoirs. Stability and rheology of the flowing emulsion porous media are key factors effectiveness EOR method. The objective this study to use microfluidics (1) quantitatively evaluate synergistic effect NPs on dynamic stability how affect properties, (2) investigate properties sweep performance flooding. A microfluidic...
The flow of multiple fluid phases in porous media often results trapped droplets the nonwetting phase. Recent experimental and theoretical studies have suggested that nanoparticle aqueous dispersions may be effective at mobilizing (oil) media. Hypotheses to explain observation include nanoparticles' modification solid wettability, droplet stabilization, changes interfacial tension interface rheology. However, because it is difficult observe behavior on pore scale, how those factors...
Summary We present a study of the low–salinity effect during oil recovery using microfluidics experiments in an attempt to narrow gap between pore–scale observations and porous–media–flow mechanisms, explain one type with delayed without presence clay. A microfluidic toolbox is used, including single–pore–scale microchannels, pore–network–scale (approximately 102 pores) micromodel, reservoir–on–a–chip model 104 pores heterogeneity), all 2D connectivity. Experiments at single–pore scale...
Abstract Miscible gas injection is proposed here for improved oil recovery in unconventional, oil-rich shale reservoirs. The ultra-low permeability of makes from well to difficult; thus it that injected into a hydraulic fracture along horizontal and production occurs an adjacent fracture, intersecting the same well. Compositional reservoir modeling was performed investigate effectiveness scheme. computational domain consists two hydrofrac half-stages capture detailed information fluid flow...

Optical microscopy was used to visualize the flow of two phases [British Petroleum (BP) oil and an aqueous surfactant phase] in confined space, three-dimensional, transparent, natural porous media. The media consisted water-wet cryolite grains packed inside cylindrical, glass microchannels, thus producing microscopic beds. Primary drainage BP displacing phase studied at capillary numbers that varied between ${10}^{\ensuremath{-}6}$ ${10}^{\ensuremath{-}2}$. confinement space had a...
Dissolving ionic-liquid droplets of 1-hexyl-3-methylimidazolium tetrafluoborate ([Hmim][BF4]) into surrounding 1-pentanol phase were investigated inside a glass rectangular channel microscopically at 23 ± 0.5 °C. The Epstein−Plesset mathematical model was used to fit the change drop radius with respect time. With solubility data ionic liquid (IL) in determined from UV−visible spectroscopy, diffusion coefficient determined. Measurements conductivity and spectroscopy various concentrations...
We perform a reservoir simulation study to investigate injection of gel systems, including cross-linked polymer gels and silica gels, as treatment method for fracture sealing leakage remediation in CO2 storage reservoirs. An adsorption permeability reduction approach was adopted model the by gel. The results show that both systems successful can reduce 103 times over 25 years post-treatment injection. effects operating conditions, heterogeneity, associated uncertainty on were investigated...
