“…Carbon nanotube (CNT) toughened epoxy coated sand was reported by Xia [22], high performance coated sand proppant was obtained with obvious improved conductivity. Epoxy/phenolic binary mixture coated sand was reported in our previous work [23], the sphericity and roundness of the obtained proppant was further enhanced to 0.85. Multicomponent polymer (polystyrene, polymethyl methacrylate, epoxy) coated sand was investigated by Krishnan and co-workers [24,25], ultra-low density proppant with bulk density less than 1.5 g•cm −3 was obtained, but the improvement of crushing rate and sphericity is not obvious.…”

Design, synthesis and application of low-density proppant (LDP) are of great significance for efficient and clean exploitation of low permeability oil and gas. On the basis of a brief introduction of hydraulic fracturing and the application of traditional proppants, this review systematically summarized the polymer application progress in LDP, including coated sand, coated ceramics, coated nutshells, especially for polymer composites based ultra-low density proppant (ULDP). Finally, the existing problems and future development direction are also prospected.

“…In the exploitation of oil and gas wells, fracturing supports are required to prevent rock fissures deep in the formation [4][5][6]. The fracturing fluid containing the proppant is injected into cracks of the rock layer under high pressure to provide a high-permeability passage for oil and gas circulation, improve the oil guiding rate, and increase oil and gas production [7][8][9][10].…”

This study investigates a new type of high-performance coated sand as a petroleum fracturing proppant material. Modified quartz sand was coated with a layer of low-density resin to reduce the overall density of the proppant, thereby improving the suspension of the proppant in the fracturing fluid. Resins play an important role in the preparation of coated sand fracturing proppants. The mechanism of sand formation was studied by examining the phase composition and microstructure of the coated sand proppant. The results demonstrate that when the polyimide resin content is 6% and the curing temperature is 180 °C, the proppant exhibited the best performance with an apparent density of 1.592 g/cm3 and a breakage ratio of only 3.22% under 55.2 MPa. Compared with the widely used epoxy resin-coated support agent and phenolic resin-coated support agent in the early stage, their crushing rate decreased by 5% and their acid solubility decreased by 2%. Hence, this study is worthy of attention.

The use of fracturing proppants is a key element of hydraulic fracturing operations in the oil and gas industry. The selection of proppants with superior performance is critical to ensure efficient and effective hydraulic fracturing. Proppant technologies are developing rapidly. Therefore, standardization of proppant evaluation is necessary to ensure accurate proppant evaluation during proppant production. Although the API and ISO have released a number of recommended practices for this purpose, there are still significant gaps in them. This is because several hypotheses regarding proppant performance, including proppant embedment and diagenesis, and their influence on proppant conductivity, are still not fully clear. Numerous proppants have been produced within the petroleum industry, featuring diverse compositions, sizes, shapes, and intended uses. While many proppants consist of silica or ceramics, there is growing interest in advanced types such as ultra-lightweight proppants. These innovations aim to minimize settling and enable transport using low-viscosity fluids. Moreover, to reduce expenditures, it is common practice in hybrid completions to mix proppant of different sizes according to stimulation design objectives and assumptions. Proppant can be equally mixed, separated by tail-in, or mixed with dominating concentrations of a specific size, depending on the type of fluids, viscosity, and anticipated settlement velocity. Surface modification involves altering the surface properties of the proppant to improve its adhesion to the fracture face and to reduce embedment and fines generation. Surface modification techniques include silane treatment, plasma treatment, and chemical treatment. The method can maintain oil flow channels after the hydraulic fracturing operation for a very long time. Proppant flowback, fines generation, and gel degradation are the key factors that contribute to a proppant pack losing permeability. Proppant pack conductivity can be increased, and well cleanup can be hastened, with the aid of a surface modification. This review paper aims to provide a comprehensive overview of proppant and its types, proppant performance assessment, and methods to enhance proppant performance. We discuss various techniques to evaluate proppant performance, including crush resistance, conductivity, embedment, and closure stress. Additionally, we highlight the importance of selecting the most appropriate proppant type for a particular well based on the formation properties and proppant characteristics. Furthermore, we explore recent advancements in proppant enhancement methods, such as coating, sintering, altering proppant surface, and consolidation, and their effectiveness in improving proppant performance. The comprehensive review provides insight into current industry practices and highlights potential areas for future research to improve fracturing proppant performance.
