Ceramic Proppant, also known as oil fracturing ceramic proppant or sintered bauxite proppant, is a high-performance downhole material essential for hydraulic fracturing operations in oil, gas, and shale formations. Manufactured from premium bauxite ore through fine powder granulation and high-temperature sintering, these spherical ceramic granules are pumped into formation fractures to prop them open after pressure release, thereby maintaining high fracture conductivity and enabling sustained hydrocarbon flow from the reservoir. When used in hydraulic fracturing, ceramic proppants can increase well production by 30-50% and extend the service life of oil and gas wells.
Available in four industry-standard strength grades—52MPa (7.5K psi), 69MPa (10K psi), 86MPa (12.5K psi), and 103MPa (15K psi)—suitable for wells from shallow formations to the deepest high-pressure reservoirs.
Precision manufacturing ensures sphericity and roundness values exceeding 0.9, ensuring uniform packed conductivity and minimizing flow resistance.
Low acid solubility (<7%) ensures chemical inertness against reservoir fluids and fracturing fluids, maintaining structural integrity in aggressive downhole environments.
Withstands high-temperature conditions in deep wells without degradation, maintaining reliable performance under extreme thermal stress.
Available from ultra-lightweight to high density grades, with bulk density ranging from <1.65 g/cm³ to >2.00 g/cm³, enabling efficient proppant transport and placement within fractures.
Field data demonstrates that wells using ceramic proppant achieve 30-50% higher production rates compared to conventional quartz sand, with extended well service life.
