Petroleum proppant also called oil fracturing proppants.

Petroleum proppant also called oil fracturing proppants. When oil and gas after deep mining, high closure pressure after fracturing low permeability deposit processing, the hydrocarbon formation split, passage of oil and gas from the cracks formed in the collection out of the fluid injected into the rock grassroots needs at this time, to exceed the formation fracture pressure strength, so that cracks the rock around the wellbore,  Proppant into the formation along with the high-pressure solution filled in cracks in the rock, play a supporting fissures not because of stress release and closing action, thereby maintaining high conductivity, so that oil and gas flow, increase production.
