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 11):
A process for improving the durability of a self-suspending proppant comprising a proppant particle substrate, a binder on the surface(s) of the proppant particle substrate, and a layer of a hydrogel-forming polymer in form of powder particles bound to the surface(s) of the proppant particle substrate by the binder, the process comprising applying a crosslinking agent capable of crosslinking the hydrogel-forming polymer to these powder particles after they have been contacted with the binder.
