ABSTRACT:
High strength, chemical resistant particulate solids are provided which are particularly suitable for use in treating subterranean zones penetrated by well bores such as for forming gravel packs, as fracture propping agents and as cement composition structural fillers. The high strength, chemical resistant particulate solids are formed by coating solids with the reaction product of an organofunctional silane and an aryl acid halide.
