Abstract:
The durability of a self-suspending proppant which is made by applying a layer of a hydrogel-forming polymer in powder form to a binder carried on the surfaces of a proppant particle substrate is improved by applying a crosslinking agent for polymer to these powder particles after they have been bound to the binder.

Claim (Index 8):
The self-suspending proppant of  claim 1 , wherein the self-suspending proppant exhibits (a) a volumetric expansion as determined by the Settled Bed Height Analytical test described in the specification of \u22651.5, (b) storage stability as reflected by the fact that it remains free flowing after having been subjected to a relative humidity of about 80%-90% for one hour at 25-35\u00b0 C., and (c) a durability of \u22651.5 as determined by the Shear Analytical Test described in the specification.
