“…21−23 The practical applications of a variety of nanoparticles, such as SiO 2 , 24,25 TiO 2 , 26 ZrO 2 , 27 and Fe 3 O 4 , 28 have concentrated on reservoir characterization, nanotracking, well drilling, and enhanced oil recovery (EOR). Furthermore, the main applications of nanoparticles in the field of EOR include foam stabilization, 25,29 emulsion stabilization, 30 polymer viscosity improvement, 26,31 and oil− water interfacial tension reduction. 32 However, the majority of widely used nanoparticles are mainly metal oxides and nonmetal oxides, which are more or less prone to cause environmental pollution.…”

Review on Enhancing Rheological Characteristics of Viscoelastic Surfactant Fracturing Fluids by Nanoparticles: Advances, Challenges, and Perspectives

“…Surfactants in water form micelle aggregates with different shapes like spherical or cylindrical as well as lipid bilayers. The shape is determined by the surfactant’s chemical composition and the size relationship between the hydrophilic head and hydrophobic tail . The properties of surfactant-induced materials and their interaction with other chemicals are significantly affected by changes in the head and tail groups.…”

“…The shape is determined by the surfactant's chemical composition and the size relationship between the hydrophilic head and hydrophobic tail. 9 The properties of surfactant-induced materials and their interaction with other chemicals are significantly affected by changes in the head and tail groups. Surfactants consist of a hydrophilic headgroup that attracts water and a hydrophobic tail group that repels water, as depicted in Figure 1.…”

Improvement of the Rheological Behavior of Viscoelastic Surfactant Fracturing Fluids by Metallic-Type Nanoparticles

“…The addition of nanoparticles leads to improved plateau modulus, relaxation time, and zero shear viscosity in nanoparticles−VES fluids. 37,44,51 In the past, the addition of nanoparticles to the VES solution to improve its performance was considered to be detrimental to production because these particles act as pore blockers, thereby affecting the permeability and efficiency of the reservoirs. 52,53 However, it has been found that selected particles of nano size and less than 100 nm can improve the performance of VES fluids.…”
