A photo-responsive system composed of an imidazolium-type surfactant 1-hexadecyl-3-methylimidazolium bromide ([C16mim]Br) and a commonly photosensitive aromatic compound trans-cinnamic acid (trans-CA) was studied through UV spectra, 1H NMR, rheological measurements. In aqueous solution, the compounds [C16mim]Br trans-CA can self-assemble to form viscoelastic wormlike micelles. Through irradiation, CA molecules exhibit molecular photoisomerization from trans- cis-, which results in change...
Two zwitterionic surface-active ionic liquids (SAILs), 3-(1-hexadecyl-3-imidazolio) propanesulfonate (C16IPS) and β-naphthalenesulfonate (C16IPS-Nsa), were evaluated for their potential application in chemical enhanced oil recovery. It was found that the SAILs had a higher interfacial activity than traditional SAILs. Interestingly, C16IPS-Nsa molecule with large hydrophobic group greater ability reducing tension (IFT) of water/crude oil. Moreover, systematic investigations dynamic IFT salt...
We report a facile, green, and high yielding approach for the synthesis stabilization of relatively monodisperse gold nanoparticles using typical nonionic biosurfactant ethoxylated sterol (BPS-30). The obtained capped by BPS-30 not only showed remarkable stability after several months storage under ambient conditions, but also exhibited exciting in concentrations electrolyte aqueous solutions such as acid, base, salt, even physiological phosphate buffered saline (PBS)....
Abstract To further clarify the optimal target layer in horizontal section of Wufeng–Longmaxi shale, we selected 126 shale samples from Formations (Long1 1 to Long1 4 and 2 submember) as primary study objects perspective microscopic pore structure. We conducted this experimental on structure according various methods, including low-temperature nitrogen adsorption carbon dioxide experiments, atomic force microscopy, nano-computed tomography scanning. calculated fractal dimensions at different...
Abstract Among the different nanostructures that have been demonstrated as promising materials for various applications, three–dimensional (3D) attracted significant attention building blocks constructing high-performance nanodevices because of their unusual mechanical, electrical, thermal, optical, and magnetic properties arising from novel size effects abundant active catalytic/reactive sites due to high specific surface area. Considerable research efforts devoted designing, fabricating,...
Abstract Small-angle neutron scattering and high-pressure mercury intrusion capillary pressure testing are integrated to analyze the pore size distribution of broad sense shale oil reservoir samples Permian Lucaogou Formation in Jimsar Sag, Junggar Basin, China. The results show that, compared with measurement method integrating gas adsorption intrusion, combination small-angle can more accurately characterize full-scale distribution. curve rock study area includes two types: declining type...
Lamadian Oilfield has entered a high water-cut stage after long-term water flooding, and injected circulates in high-permeability channels. Constant-rate constant-pressure mercury injections were used to study the change physical properties of reservoir during development by flooding that features pore structure before flush. The constant-rate injection analysis shows throat radii main infiltration paths are enlarged radius distribution remains constant suggesting infiltrating controlled...
Gemini-like surfactants were fabricated by combining sodium dodecyl benzene sulfonate and butane-1,4-bis(methylimidazolium bromide) at the interface evaluated for their ability to reduce interfacial tension between water a model oil.
Controlled synthesis of gold nanorings was realized by reducing chloroauric acid in aqueous mixed solutions cetyltrimethyl ammonium bromide (CTAB) and sodium dodecyl sulfate (SDS). It is revealed that the nanowires are induced to fabricate with an average diameter ~300 nm. The formation can be achieved one step. A variety nanostructures, such as short nanowires, nanorings, nanostars a number soft protuberances nanopolyhedra, could readily obtained simply changing CTAB/SDS molar ratio. Both...
The rapid and cost-effective quantitative characterization of broad-sense shale oil reservoirs is highly challenging due to the complex lithology strong heterogeneity strata. In this paper, pore structures surface roughness samples various lithologies from a reservoir were studied using atomic force microscopy (AFM) open-source Gwyddion analytical software. morphology was reconstructed both two-dimensionally three-dimensionally AFM data for mudstone, siltstone, dolarenite in reservoir....
Abstract Potassium perfluorooctane sulfonate (KPFOS) and sodium (NaPFOS) exhibit poor surface activities in aqueous solution at room temperature because of their high Krafft points. In this work, we attempted to increase the solubility KPFOS NaPFOS consequently improve with p ‐methylbenzene (BS) urea, which are typical hydrotropes industrial applications. The effects BS urea on tension solutions were investigated 25 °C. When added, effectiveness reduction was greatly enhanced showed higher...
Cross-linked polymer flooding can increase oil recovery 10 to 20% over conventional waterflooding, while using a lower concentration of than flooding. Based on production data from developed field, the average incremental by is only 10%, indicating that much bypassed. We need know how this bypassed distributed design an optimal development strategy. Numerical simulations have been performed study mechanisms For coarsening downward sedimentary cycle, simulation model was divided into five...
It is generally considered that complexes of cyclodextrins (CDs) with ordinary surfactants are not surface-active in water. In this work, aqueous mixtures α-CD, octyltriethylammonium bromide (OTEAB), and sodium perfluorooctanoate (SPFO) were studied by surface tension measurements. Comparison the experimental results simulated ones premicellar region showed ability α-CD/OTEAB to participate surface-adsorbed layer was dependent on overall net charge surfactants: for excess-SPFO system, did...
