Proppants are synthetic or natural grains such as coated sand or sintered bauxite ceramics used in the oil well drilling industry to hold fractures open around the wellbore to enhance fluid extraction after hydraulic fracturing processes. They can increase the output of Oil & Gas wells.

There are a variety of hydraulic fracturing proppants, such as quartz sand, aluminum balls, walnut shells, glass beads, plastic balls, ceramic, resin-clad sand.

Ceramic fracturing proppants are a product of ceramic particles with high fracture strength, mainly used for oil field down hole support to increase oil and gas production, an environmentally friendly product. This product uses high-quality bauxite and other raw materials, ceramic sintering is a alternative product of natural quartz sand, glass balls, metal balls and other low-strength proppants, has a positive effect to the oil and gas production.

Silica sand is used throughout the world, and in so many different ways it is hard to imagine a world without it. From water filtration, to glass manufacture, to industrial casting, to sand blasting, to producing concrete, to adding texture to slick roads, to oil fracturing use, silica sand impacts every aspect of daily life. At industrial scales, silica sand always cost very low.

Resin Coated Sand: Generally, dry silica sand is coated with Phenolic Novalac liquid resin in batch mixture with catalyst and subsequently coated sand is passed through a heating chamber for complete curing.

As new proppants develop, resin-coated proppants continue to evolve and become more specialized to specific wells and the geological conditions downhole. The resin technology is also being engineered to meet the needs of deeper wells which translate to higher pressures and temperature environmental conditions that the proppants must be able to withstand.
