“…Dai et al [46] also used the CTAB and NaSal to prepare a WLM system, which could be served as VES fracturing fluid. Besides, the cellulose derivatives, such as carboxymethyl hydroxyethylcellulose (CMHEC), have been used to viscosify the fracturing fluids [3,[47][48][49] because of the cellulose derivatives' proper properties (easy availability, economic efficiency, low toxicity, etc.) The synergy between polymers (e.g., CMHEC) and viscoelastic surfactants has been found by many researchers in recent years [2,5,[46][47][48][49] .…”

The surfactant-polymer-based (S/P) fracturing fluid combines the advantages of the surfactant-based and polymer-based fracturing fluids. In this study, the synergistic tackifying of cationic surfactants and carboxymethyl hydroxyethyl cellulose and the potential application in hydraulic fracturing fluid was investigated. Firstly, cetyltrimethylammonium chloride (CTAC) and salicylic acid (SA) with a weight ratio of 4:1 were optimized as the main agent of the small molecule surfactant gel, which was then mixed with carboxymethyl 2-hydroxyethyl ether cellulose (CMHEC) and salicylic acid (SA) to obtain the S/P gel. The proppant suspension performance, gel-breaking properties, salt-resistance and thermal stability of the optimized S/P were evaluated to confirm their potential application in the hydraulic fracturing fluid. These results showed that the performance of the S/P fracturing fluid system was much better than the performance of the surfactant fracturing fluid and also the performance of polymer fracturing fluid.

“…Microrheology is a new field of rheological methods studying the viscoelastic behavior of soft matter such as emulsions, suspensions, gels, or colloidal dispersions at the micrometer scale [17]. Li et al [18] obtained the intrinsic crosslinking and gel-breaking rheological kinetics equations, which can effectively describe the crosslinking and gel-breaking processes. Mohsen Ramezani et al [19] continuously monitored the milk fermentation process, and the test results were confirmed by pH, rheology, and texture monitoring.…”

Chemical foaming technology is widely used in the preparation of silicone rubber foam and is attributable to its one-step molding capability and eco-friendly production processes. The microrheological properties of silicone rubber play a pivotal role during the foaming process. In this study, Rheolaser Lab (Formulaction, Toulouse, France) was used to conduct in situ examinations for the influence of a crosslinking agent on the microrheological properties of silicone rubber foam for the first time. This study monitors the entire reaction process of silicone rubber foam from liquid to solid, as well as the matching of crosslinking and foaming reactions. Various parameters, including solid–liquid balance, elasticity index, and macroscopic viscosity index, are measured to analyze the microrheological properties of silicone rubber foam. The results show that the silicone rubber foam exhibits good microrheological properties, thereby demonstrating excellent performance at a crosslinking agent content of 2%. Through adjusting the experimental conditions, a sustainable and efficient approach was proposed for better cellular structure control in the industrial preparation of silicone rubber foam.

Polymer hydraulic fracturing is important for increasing production during petroleum exploitation. After fracturing, the high-viscosity polymer should be completely decomposed by gel breakers (ammonium persulfate [APS]) to realize high conductivity in the proppant pack. A new series of polyaniline microcapsules loaded with APS for the preparation of delayed-release gel breakers were synthesized via in situ polymerization. The silica nanoparticles were doped in polyaniline to control the release of the encapsulated APS. The morphology, shell wall thickness, and elemental composition of the microcapsules were characterized by scanning electron microscopy, transmission electron microscopy, and two-dimensional scanned energy-dispersive X-ray spectroscopy. The results revealed that the microcapsules were irregularly spherical with average diameters of about 5-6 μm and had shell thicknesses of 150-300 nm, and the silica nanoparticles had been successfully doped in the polyaniline shell. The microcapsules had a burst release pattern, and their initial release time was precisely controlled by adjusting the concentration and temperature of the sodium hydroxide solution. With increased demands for high performance delayed-release microcapsules, the prepared polyaniline microcapsules loaded with APS show great potential for practical applications in petroleum exploitation, self-healing coating, fiber printing, and grease.
