“…This petroleum is often found in reservoirs with low permeability, displacement, and a varied composition. Hydraulic fracturing is increasingly being viewed as a viable strategy for improving oil production from these reservoirs [63]. In water-based fracturing fluids, cellulose derivatives are mostly used as gelling agents; however, they can also be used in other fracturing fluids as thickening stabilizers and leakage-reducing agents.…”

Hydraulic fracturing is vital in recovering hydrocarbons from oil and gas reservoirs. It involves injecting a fluid under high pressure into reservoir rock. A significant part of fracturing fluids is the addition of polymers that become gels or gel-like under reservoir conditions. Polymers are employed as viscosifiers and friction reducers to provide proppants in fracturing fluids as a transport medium. There are numerous systems for fracturing fluids based on macromolecules. The employment of natural and man-made linear polymers, and also, to a lesser extent, synthetic hyperbranched polymers, as additives in fracturing fluids in the past one to two decades has shown great promise in enhancing the stability of fracturing fluids under various challenging reservoir conditions. Modern innovations demonstrate the importance of developing chemical structures and properties to improve performance. Key challenges include maintaining viscosity under reservoir conditions and achieving suitable shear-thinning behavior. The physical architecture of macromolecules and novel crosslinking processes are essential in addressing these issues. The effect of macromolecule interactions on reservoir conditions is very critical in regard to efficient fluid qualities and successful fracturing operations. In future, there is the potential for ongoing studies to produce specialized macromolecular solutions for increased efficiency and sustainability in oil and gas applications.

“…CMHEC has an excessive bonding potential and hydration on the suspended solids with very good flocculation, however, due to nonionic hydroxyl the presence of ethyl group, in contrast with the CMC and salt, it is extra compatible. Also, another advantage is the cross-linking ability of multivalent cation, which can significantly improve the viscosity of solutions [31].…”

For several decades, cellulose and its derivatives have been used in various fields of food processing and their applications have become increasingly important. Nutritionally, cellulose is known as dietary fiber and is used as a functional food component. Many new technological needs were recognized since developing of industrial products and, therefore, cellulose modifications (chemically or physically) also have been considered. The various important properties for using these compounds include organic solubility, gel and film formation ability, make mucoadhesive system, high swelling, hydrophilic and hydrophobic features, act as viscosifying agent, and thermoplastic effects in food systems. Thus, the most typical technological role of these cellulose’s characteristics can be mentioned as edible coating (in fruits and fried products), edible film, emulsification, stabilizing agent, rheology control, suspending agent, diffusion barrier, encapsulation, extrusion, molding, and foam stabilizer in food industry. The new innovations can be mentioned as the production of bacterial cellulose, developing the smart packaging, and the preparation of nanocellulose with environmentally friendly processes. Finally, with the expansion of the usage of cellulosic materials, a reevaluation of their food safety has been carried out. Also, the legal guidelines related to the use of these compounds as raw materials have been provided for manufacturers.

“…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.
