摘要 |
Low density composite particles made of a binder and filler material are provided for use in subterranean formations. The filler includes low density filler and optionally other filler. The binder includes a polymer and optionally cement. The particles may be employed as proppants useful to prop open subterranean formation fractures. The particles are also useful for gravel packing in subterranean formations, water filtration and artificial turf for sports fields. Methods of making the composite particles are also disclosed. |
