1.Proppant Definition
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 process. They can increase the output of Oil & Gas wells.

2.Ceramic proppant
Ceramic proppant is 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.

3.Functions
In oil and gas deep well mining, the high-pressure low-permeability deposits after closure fracturing treatment, the split rock containing oil and gas, oil and gas from the formation of cracks in the collection out of the channel. Ceramic support material with high-pressure solution into the formation along with filling in the cracks in the rock, play a supporting stress release due to crack closure is not the role, so as to maintain high conductivity, so that oil and gas flow, to increase production. Practice has proved that using ceramic proppant fracturing of oil wells can increase production by 30-50%, and also to extend the service life of oil and gas wells.
