Well treatment fluid compatible self-consolidating particles

A process for the preparation of a self-consolidating proppant for well treatment fluids comprising:

• providing a particulate substrate having a size between about 6 mesh and about 200 mesh;
• forming an inner coating on said particulate substrate of a fusible curable novolac resin;
• forming an outer coating on said particulate substrate of a heat-curable resole resin;
• and
• subjecting the resulting coated particulate substrate to heat downhole in a well sufficient to cure said outer coating while maintaining said inner coating in a curable state.

A process for the preparation of a self-consolidating proppant for well treatment fluids, comprising:

• providing a particulate substrate having a size between about 6 mesh and about 200 mesh;
• forming an inner coating on the particulate substrate of a first curable resin;
• forming an outer coating on the particulate substrate of a second curable resin, where the second curable resin is curable at conditions that leave the first curable resin uncured;
• subjecting the resulting resin-coated particulate substrate to conditions sufficient to substantially cure the outer coating while maintaining the inner coating in a fusible curable state.
