“…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.

“…It has high chemical stability, thermal stability, sphericity, and compressive strength (Szymanska et al, 2016;Man and Wong, 2017). Furthermore, it can form fracture channels and improve the reservoir permeability during hydraulic fracturing (Assem and Nasr-El-Din, 2017;. Thus, it is an optimal choice as a temporary plugging microcapsule core material.…”

Ocean gas hydrate is a potentially efficient and clean oil and gas alternative energy resource. Wells with complex structure, such as horizontal wells, can improve the extraction efficiency; however, drilling operations face challenges such as wellbore instability and reservoir damage due to the complex interaction between drilling fluids and hydrate reservoirs. This work presents a ceramsite temporary plugging microcapsule that uses ceramsite modified by 3-aminopropyltriethoxysilane as the core material and chitosan and sodium alginate as shell materials. It exhibits high strength during drilling and excellent plugging effects. After the action of bioenzymes, it can easily be dissolved, leading to high permeability post-drilling. The analysis and performance evaluation of ceramsite microcapsules show that their particle size is generally 40 µm, which can match the pore size of the hydrate reservoir depending on the number of encapsulation layers. Bioenzyme optimization at 15 • C yields the best permeability recovery of 74.5% for the low-temperature composite enzyme. As the temperature rises, the permeability recovery rate of ceramic microcapsules gradually increases and the difference in permeability recovery rate between 5 and 25 • C becomes more significant. With a longer degradation time, the permeability recovery rate of ceramsite microcapsules gradually enhances and the difference in permeability recovery rate becomes smaller after 12 h. The microcapsules exhibit a specific inhibitory effect on the decomposition of hydrates. Utilizing bioenzymeresponsive ceramsite microcapsules as temporary plugging materials can establish an "isolation barrier" around the wellbore, effectively sealing off the interaction between the wellbore and the gas hydrate reservoir during the drilling process. Re-opening the flow path around the well by bio-enzymatic unblocking at the end of drilling proves to be effective in solving the problem of balancing the stability of the well wall and protecting the reservoir.

“…[5][6][7] In the previous research works, ceramic proppants were mainly prepared from high-alumina bauxite (>60 w/% Al 2 O 3 ) at a high sintering temperature. [8][9][10] Unfortunately, over-exploitation made high-grade bauxite ore less available, thereby boosting its price. In addition, new supplies of oil in the market are mainly sourced from unconventional resources such as shale oil, low-permeability rock and deep wells which drive up the production cost due to the difficulties of these processes, and put a greater pressure on the environment.…”

In this work, a phase-pure mullite proppant was prepared from calcined flint clay with a dolomite content at 1400°C. The phase composition and microstructure of proppant samples were investigated through X-ray diffraction and scanning electron microscopy. In addition to the apparent density, the breakage ratio was systematically investigated as a function of the content of dolomite. The results showed that the addition of dolomite went against the formation of cristobalite and promoted amorphous SiO2 to react with Al2O3 to form mullite. Additionally, when the content of dolomite was 4 % of mass fractions, the breakage ratio of the pure-mullite ceramic proppant was the lowest, under 52 MPa. The observation that, in the presence of dolomite, calcined flint clay can act as a precursor material for phase-pure mullite is of great industrial significance.
