IMERYS Propynite®

The revolutionary design of IMERYS Propynite® exhibits strength and proppant permeability, far in excess of conventional HSP.
Providing greater fracture conductivity and flowback control than traditional proppants, it permits high well productivity at closure stress levels in excess of 15,000 psi.
The higher pack permeability also significantly improves the mobility of the residue from high viscosity fracturing fluids, and therefore improves fracture clean-up.
