Compared to silica sand, ceramic proppant has higher strength and is more crush resistant especially where closure stresses exceed 8000 to 10,000 psi. Additionally, it is more uniform in size and shape, and has higher sphericity and roundness to yield higher porosity and permeability of the proppant bed.
Crush Resistance. Frac sand crush testing is used to determine the crush resistance of the proppant. The frac sand is crushed at a predetermined stress and then sent back through the sieve analysis to determine the percentage of fines that were produced from the original sample that was crushed.
