Green synthesise of CuO@Fe ₃ O ₄ @Xantan nanocomposites and its application in enhanced oil recovery by considering IFT and wettability behaviours

Abstract

Enhanced oil recovery (EOR) makes use of various chemical processes to extract additional oil from reservoirs, often already under production. In this study, authors investigated the role of the CuO@Fe 3 O 4 @xanthan nanocomposite (NCs) in EOR by the focus of the interfacial tension (IFT) and wettability alteration mechanisms. This NCs is synthesized from Artocarpus altilis extract using a simple, economical and green method. The prepared NCs is identified using X-ray diffraction (XRD), Fourier-transform infrared spectroscopy (FTIR), and scanning electron microscopy (SEM). Nanofluids are prepared from dispersing the synthesised NCs in water at different concentrations in order to be used in the density, viscosity, conductivity, IFT and contact angle measurements. The results showed an improvement in the values of IFT and contact angle. The IFT of oil/water is increased from 22 to 24 mN/m with increasing the concentration of the NCs from 250 to 2000 ppm. While, the wettability of the carbonate rock is remained water-wet, wherein the contact angle is raised from 28°to 58°with increasing the NCs concetration from 250 to 2000 ppm. Overall, the IFT and contact angle are only reduced when 250 ppm NCs was added to water from 28.3 mN/m and 132.6°mN/m to 22 and 34.5°.

Synthesis, Characterization, and Assessment of a CeO2@Nanoclay Nanocomposite for Enhanced Oil Recovery

“…As the entropy increases, separation pressure (disjoining pressure) between the oil and the rock surface separates the oil droplets and increases the surface hydrophilicity (i.e., altering the wettability towards a more water wet state). However, such alterations are controlled by size of the nanoparticles, surface chemistry of the rock, and salinity of interpore space [ 83 , 84 , 85 , 86 , 87 ].…”

Biogenic synthesis of copper oxide nanoparticles using leaf extracts of Cissus quadrangularis and Piper betle and its antibacterial effects

“…Plants are valuable source of compounds with reductive abilities called antioxidants. The higher bioactivity of as-synthesized nanoparticles resulted from their large surface area and preferential adsorption of the bioactive constituents from the extract onto the surface of the nanoparticles, both of which are strongly affected by the surface area, particle size and surface reactivity of the nanoparticles [15,16]. Green production of NPs involves the reduction or elimination of toxic reagents usage, which ends in a significant reduction in the number of harmful residues to human health and the environment [17][18][19][20].…”

Characterization, Micellization Behavior, and Performance of a Novel Surfactant Derived from Gundelia tournefortii Plant during Chemical Enhanced Oil Recovery

“…Generally, EOR processes are classified into main groups of chemical flooding, thermal miscible flooding, and microbial processes . Chemical EOR (CEOR) is usually applied in oil-bearing formations with two main goals: reducing the interfacial tension (IFT) between the reservoir oil and the injected fluid and improving the sweep efficiency of the injected fluid by decreasing its mobility. − …”
