Wettability alteration is an important method to increase oil recovery from oil-wet carbonate reservoirs. Chemical agents like surfactants are known as wettability modifiers in systems. However, the effectiveness of these can be increased by addition chemicals such polymers, ionic materials, and nanoparticles. The impacts nanoparticles on systems have not been reported yet, it still its infancy. In this work, effect ZrO2-based nanofluids a reservoir rock was experimentally studied. Several...
Nanofluids have been recently proposed as new chemical agents for enhanced oil recovery from reservoirs. Various nanofluids studied in that regard and reported the literature, verifying capability of nanostructured materials enhancing through alteration rock wettability. In this study, impacts different zirconium dioxide (ZrO2), calcium carbonate (CaCO3), titanium (TiO2), silicon (SiO2), magnesium oxide (MgO), aluminum (Al2O3), cerium (CeO2), carbon nanotube (CNT) on wettability rocks were...
Abstract The effect of surface modification on enhancing the magnetic heating behavior nano fluids were investigated, for this purpose Fe 3 O 4 nanoparticles synthesized using co-precipitation method and was done citric acid, ascorbic tetraethyl orthosilicate (TEOS), polyvinyl alcohol (PVA) polyethylene glycol (PEG). Experimental tests AC field in frequency 100 kHz different (H) intensities. Theoretically specific absorption rate (SAR) is independent concentration but experimental results...
Asphaltene precipitation causes several problems during crude oil production, transportation, and refinery processes. Therefore, finding an inhibitor to prevent or delay asphaltene is of paramount importance. In this work, effects TiO2, ZrO2, SiO2 fine nanoparticles in organic-based nanofluids have been investigated study their potential for stabilizing particles oil. To end, polarized light microscopy has applied determine the onset by titration dead samples from Iranian reservoirs with...
The production rate of many oil fields has been decreased during recent years. Various old chemical methods have used to exploit reservoirs, such as the use polymers, surfactant-polymer (SP), and alkaline/surfactant/polymer (ASP). Among all enhanced recovery methods, polymeric surfactants had excellent function for enhance (EOR) purposes. This study presents significant research about influence sodium dodecyl sulphate (SDS) on adsorption properties non-ionic polyvinyl alcohol (PVA) polymer....
Construction of surfaces with the capability repelling both water and oil is a challenging issue. We report superamphiphobic properties mineral coated nanofluids based on synthesized Co-doped Ce-doped Barium Strontium Titanate (CoBST CeBST) nanoparticles fluorochemicals trichloro(1H,1H,2H,2H-perfluorooctyl)silane (PFOS) polytetrafluoroethylene (PTFE). Coating these provides (with surface tensions as low 23 mN/m) repellency. Liquids high tension (such ethylene glycol) roll off without...
Nanoformulations derived from fine porous ZnO quantum dot nanoparticles (QD NPs) can offer strong potential medical applications; especially in cancer therapy. QD NPs was synthesized by sol-gel hydrothermal process, fast cold quenching and further smart surface functionalization methods to obtain ultrasmall size (1-4 nm) NPs. nanopolymer, a wetting agent, PEG co-solvent water/oil emulsion stabilizer were considered our nanofluid formulation. The resulting characterized SEM, FTIR,...
The adsorption of surfactants at the solid–water interface is important for control wetting, lubrication, detergency and in mineral flotation.We have studied adsorptions different types surfactants, cationic (Dodecyl trimethylammonium bromide, DTAB), anionic (sodium dodecyl sulfate, SDS) non-anionic (lauryl alcohol-7 mole ethoxylate, LA7) on carbonate rock presence zirconium oxide spherical nanoparticles (17-19 nm).
