Oil well stimulation treatments have been employed to improve the productivity index, either by imposing a negative skin effect through hydraulic fracturing or by reducing a positive skin effect using matrix acidizing. The commonly used stimulation fluids are polymer-based, viscoelastic surfactant-based, emulsion (oil)-based, and foam-based. The stability and performance efficiency of the stimulation fluids under harsh conditions of high temperature and high pressures have remained a critical factor. Thus, in recent times, the incorporation of nanoparticles (NPs) as additives in the fluid formulation has received significant attention. NPs have been reported as rheology modifiers, cross-linking agents, gel breakers, leakoff control additives, foam stabilizers, proppant surface modifiers, and emulsion stabilizers in different types of stimulation fluids. In this review, we discuss the application of nanoparticles in different types of stimulation fluids. The different roles of nanoparticles are highlighted. Factors affecting the performance of nanoparticles in stimulation fluids are also covered. Although laboratory experiments have shown the exceptional performance of nanoparticles, the field application of different nanoparticles in stimulation fluids is still limited.

“…The application of fibers can effectively change the rheological properties of fluids . In fracturing fluids, Elgaddafi found that fiber-containing fluids had a stronger bearing capacity on the proppant than fiber-free fluids, which could hinder the settlement movement of the proppant − and improve the proppant transport efficiency during the fracturing process, further carrying the proppant into the fracture . Kang proposed a set of temporary plugging technologies for naturally fractured formations in tight gas reservoirs in western Sichuan. , With the synergistic effect of rigid particles, fibers, and elastic particles, effective plugging is formed in the fractured stratum and the plugging pressure is increased.…”

The application of fiber in the completion fluid can improve the rheological properties of the completion fluid and the plugging quality of the production layer by the completion fluid and reduce the damage of the filtrate to the reservoir formation. However, there are few studies on the influence of fibers on the rheological properties of completion fluids and the flow behavior in pores. In this paper, plant fiber, mineral fiber, and synthetic fiber are discussed. Carbon fiber, bamboo fiber, polypropylene fiber, and polyester fiber are selected as research objects. The dependence of the rheological property of polymer solution on fiber type, fiber concentration, temperature, and shear rate is evaluated. The evaluation is carried out by observing the microscopic state of the fiber through a microscope and a scanning electron microscope, testing the rheological property parameters of the fiber with an OFITE 900 rheological tester, and fitting with the Herschel−Bulkley model. The results show that polypropylene fiber and carbon fiber have the best dispersion in polymer solution. The higher the fiber content, the greater the influence of fiber on the rheological properties of the solution. Compared with the other three fibers, carbon fiber has the greatest influence on the rheological properties of polymer solution. When the temperature is lower than 70 °C, the influence of the fiber on the rheological properties of the solution is not affected by the temperature. When the temperature exceeds 70 °C, the carbon fiber and polypropylene fiber are affected by the temperature, and the viscosity of the polymer solution is increased. The flow behavior of fiber suspensions in pores varies with the flow factor n. Carbon fiber suspensions are most conducive to the transition of polymer solution to plate laminar flow, which can improve the bearing capacity of plugging materials.
