“…Sphericity and roundness, to some extent, were also significant factors determining mechanical property of ceramic proppants. High degrees of sphericty and roundness contributed to more uniform load distribution and increased probability of enhanced transport to a wellbore and created a stable prop in a shale fracture, thereby producing the high strength . In our work, the sphericity and roundness coefficient were more than 0.9, which was believed to favor improving mechanical strength and reducing breakage ratio.…”

Ceramic proppants with excellent performance were successfully prepared by second grade bauxite. The phase structure and the microstructure were investigated via X-Ray diffraction and scanning electron microscopy. The results suggested that bulk density and apparent density constantly increased, while the breakage ratio gradually decreased with the increasing in sintering temperature. When the sintering temperature reached to 1500°C, the breakage ratio obtained lowest value of 3.6% under 52 MPa closed pressure, which satisfied the requirement of Chinese Petroleum and Gas Industry standard. Furthermore, the mode of fracture for ceramic proppants was transformed from intergranular fracture into transgranular fracture and open pores had larger influence than closed pores for breakage ratio of ceramic proppants.

“…Although resin‐coated proppants have good performance, they are seldom used at present because of their complex production process and high production cost. Ceramic proppants are artificial proppants prepared by sintering a mixture of bauxite, kaolin, and other minerals, and they have high strength, good sphericity, uniform particle size, and outstanding physicochemical stability; thus, they can ensure a fracturing effect under various complex geological and topographic conditions 17–19 . Therefore, ceramic proppants have gradually replaced quartz sand proppants and are widely used in the production of mid‐depth and deep oil and gas wells because of their good performance, convenient production, and low cost.…”

Ceramic proppants are preferred in hydraulic fracturing because of their high strength, good sphericity, and excellent acid corrosion resistance. Bauxite is the main raw material of ceramic proppants, but with the increasing depletion of bauxite resources, substitutes for bauxite need to be sought. Coal gangue is a solid waste that is rich in SiO 2 and Al 2 O 3 , making it a potential substitute for the preparation of ceramic proppants. The use of coal gangue to prepare ceramic proppants can reduce the cost of ceramic proppants and benefit environmental protection. Studies on using coal gangue to prepare ceramic proppants have been conducted and achieved progress, but further improvement can still be obtained.Here, the basic principle, progress, and prospects of coal gangue ceramic proppants are reviewed. First, coal gangue ceramic proppants are divided into two categories, namely, proppants prepared using coal gangue as an auxiliary material and proppants prepared using coal gangue as the main material. Second, the progress of research of coal gangue ceramic proppants is summarized from the perspective of additives, and the influence of different kinds of additives on the sintering temperature and performance of proppants is discussed. Lastly, the future prospects of coal gangue ceramic proppants are presented.

“…Layered clay minerals such as kaolinite and structurally similar minerals are important in engineering applications (Murray, 2000; Chen et al ., 2008; Abdi-Khangah et al ., 2018). The mechanical properties of clay minerals have received significant attention in mining engineering, resource exploration and geotechnical investigations (Wang & Cates, 2001; Szymanska et al ., 2018; Emmanuel et al ., 2019). In addition, clay minerals in geological formations can alter seismic-wave propagation, so understanding the mechanical properties of clays helps us to understand, interpret and model the seismic responses of geological structures (Mayoral et al ., 2016).…”

A molecular dynamics study of the mechanical properties of kaolinite under uniaxial and isothermal compression at various temperatures

et al. 2022

Uniaxial and isothermal compression tests of kaolinite were carried out using molecular dynamics simulations. Five different temperatures (300, 400, 500, 600 and 700 K) and pressures ranging from 0.0001 to 50 GPa were selected to study the temperature and pressure effects on the mechanical properties of kaolinite. As kaolinite may undergo a phase transition at ~1572 K, a highest temperature of 700 K was chosen to avoid such structural change. The Young's modulus, strength and elastic constants of kaolinite under various temperatures were calculated, and the relative change of the elastic constant C33 with temperature was found to be almost 12 times greater than the relative change of the interlayer constant C11. The microstructures under various compressive strains were tracked and they exhibited various failure modes in three directions. The temperature and pressure effects on the mechanical properties of three crystal directions were analysed. The results showed that the Young's modulus of the z-direction is the most affected by temperature; however, the influence of temperature on the strengths of the three crystal directions was the same. In addition, the structure of the z-direction was the most sensitive to temperature under the same hydrostatic pressure due to the weak interactions between layers.
