“…As the formation energy is insufficient, the oil recovery method through maintaining formation pressure by gas or water injection is the secondary oil recovery with the range of 30–40% OOIP. For the further development of the oil field, the tertiary oil recovery method is adopted gradually, − which includes changing the viscosity of the crude oil by injecting a fluid or heat or changing the interfacial tension between the crude oil and other media in the formation or using physical and chemical methods for discontinuous and hard recovery of remaining oil in the oil formation. Theoretically, the tertiary oil recovery can achieve up to 60–70% OOIP.…”

Nanoparticles (NPs) have been applied in enhanced oil recovery (EOR) successfully over the last couple of decades, due to their unique property inherited by the small size (most of the studies focused on sizes smaller than 50 nm) and abundant surface functional groups. The important mechanism of EOR using a NP-based nanofluid is the change of interfacial properties. However, the effect of the nanoparticle size on the same type of oil recovery has not been systematically studied, especially the larger size. Therefore, in this research, SiO 2 NPs of different sizes, namely, ∼60, ∼100, ∼200, and ∼300 nm, were synthesized using the Stober method and the properties of the NP-based nanofluids were investigated, including interfacial tension (IFT), contact angle, viscosity, capillary pressure, and the ability to extract oil. The experimental results showed that as the SiO 2 NP size decreased, there was a little increase in the IFT, oil contact angle, viscosity, and capillary pressure. With a NP concentration of 0.3 wt % in 3 wt % NaCl brine, the ∼60 nm SiO 2 NP-based nanofluid was the most efficient oil-displacing agent to recover oil from the mediumpermeability core sample of Daqing Oilfield. Therefore, according to the discussion of the selective preference for SiO 2 NP sizes, the developed nanofluid is a promising new material in medium-permeability reservoirs for enhanced oil recovery.

Herein, we report a facile preparation method for mechanically robust and thermally enhanced sand‐polyacrylamide (PAM)‐2D‐nanofillers composite hydrogels and their application in water shutoff. To prepare the sample, 4 wt% of aqueous PAM solution is mixed with organic cross‐linkers of hydroquinone (HQ) and hexamethylenetetramine (HMT) in a 1:1 weight ratio and aqueous potassium chloride (KCl) solution and with a specific amount of 2D‐nanofillers such as commercial graphene (CG) nanosheets or boron nitride nanoparticles (BN NPs). A specific amount of the above solution is added to sand, well mixed, and subsequently cured at 150°C for 8 h. The prepared composite hydrogels were characterized by Fourier‐transform infrared spectroscopy (FT‐IR) for chemical composition and X‐ray diffraction (XRD) for successful hydrogel coating onto the sand particles. Thermal stabilities of the samples have been evaluated by differential scanning calorimetry (DSC). Mechanical properties (storage modulus [G′]; loss modulus [G″]; gel strength (G′/G″); and damping factor [G″/G′]) of the samples were determined using dynamic mechanical analyses. The thermal stability of the samples has reached as high as 193.4°C, while the gel strength is found to be a maximum of 16.2. The water swelling ratio for the composite hydrogel has reached a maximum of 1100% within 1 h.
