“…Ceramsite has a good sphericity, high strength, high compressive strength, and is less susceptible to fracturing [17][18][19][20]. However, its density is relatively high compared with that of quartz sand, and the high energy consumption and price of ceramsite prevents its implementation [21][22][23][24][25][26][27]; ceramic proppants are suitable for deep oil and gas wells with high closure pressures.…”

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.

“…In order to improve the sand transportation efficiency of clean water or lowviscosity fracturing fluid, the petroleum industry has developed a large number of new products and processes, including self-suspension proppant and low-density proppant. They can significantly improve the efficiency of support transportation, but at present, the manufacturing of self-suspension proppant and low-density proppant is relatively complex and costly, and it cannot solve the problems of proppant backflow [11][12]. In order to prevent proppant backflow, a film-coated proppant was introduced, which not only has higher mechanical properties but also effectively prevents the backflow of proppant in the blasthole.…”

Aiming at solving the problem of sand production and limited sand carrying distance during slick water fracturing of unconventional oil and gas reservoirs, an efficient proppant placement technology based on fiber structure stabilizer is innovatively developed: During the sand fracturing construction of oil and gas wells, the fiber and fiber structure stabilizer is pumped into the reservoir with proppant in sand-adding stage, and the components including fiber, stabilizer, proppant and drag reducing agent form a stable net-like structure to improve the proppant placement distance and stacking height, thus increasing the effective support volume. With this technology, the seepage mode of artificial fracture is changed and its conductivity of supporting fracture body is greatly improved; the critical flow rate of proppant flowback is increased up to tens of folds compared in the same operation condition. It has been applied in more than 30 wells of tight gas and shale oil and gas in China. The sand production rate after fracturing in tight gas was 79% lower than conventional fracturing without additives of fiber and fiber structure stabilizer. The effect of proppant flowback control and hydrocarbon stimulation is remarkable.

“…Other studies have explored the influence of proppant density, strength, and chemical coating on fracture performance, emphasizing the need for proppants with high crush resistance and compatibility with fracturing fluids. Proppant's compatibility with the fluid is considered in terms of chemical interactions, wettability and suspension stability that helps understanding the interaction between proppants and fracturing fluid to ensure effective proppant distribution and avoids issues of proppant settling and flow-back [21,22,23].…”

The efficiency hydraulic fracturing procedure must be enhanced by introducing various types of proppants to extract maximum production from low permeability reservoirs. The problem with hydraulic fracturing procedure is the selection of appropriate proppant type for specific composition of reservoir rock. Therefore, this study provides an experimental investigation on flow behavior of proppant-based fracturing fluid through regular fracture geometries in different rock samples. The challenge for conducting such an investigation is to achieve detailed fracture response of fracture network while fracturing a rock at surface in laboratory. For this purpose, a specially designed assembly on laboratory scale was used to perform an experiment on fracturing. The assembly was designed to hold cylindrical core samples which are either outcropped from the original location or by forming limestone, sandstone molds. The results of this revealed that the permeabilities were altered from 2.3 to 3.3mD for limestone samples, 2.2 to 2.9mD for shale samples and 2.1 to 3.5mD for sandstone samples. Moreover, mechanical behavior was insightful for shale samples as their tensile strength ranged from 1080 to 130 psi with the average magnitudes of 700 to 720 psi. The bulk density of proppants was found to be 95.90 lbm/ft³ and the settling packed porosity of the proppants was calculated to be 0.420 with the specific gravity of 2.65. Further, the pattern of geometry observed in sandstone and shale formation was vertical linear while in limestone the shape of fracture was parabolic therefore such proppants are more fracture length yielding for sandstone and shale formations. The study concludes that limestone formation requires different configuration while fracturing through proppants and shale and limestone has similar fracture behavior while proppant based hydraulic fracturing. The outcomes of this study are very useful to design any fracture activity considering the fracture behavior of different formations to specific type of proppants.
