After the extraction of oil

proppant sand manufacturers and fracturing proppant wells over time, high-low permeability deposit after closing pressure fracturing treatment, the rock cracked petroleum, oil and gas from the cracks in the channel formed by the pooled out. Ceramic proppant material along with high-pressure solution is filled into the formation of cracks in the rock, the play not because of stress release propped fracture and closed, thereby maintaining high conductivity, so that the oil and gas flow, increase production. Ceramic proppant is widely used in the exploitation of oil and gas, to increase oil and gas production, and does not support the ground subsidence
