Abstract
Composite particles made of a binder and filler material are provided for use in subterranean formations. The filler is finely divided mineral and optional fiber. The particles are proppants useful to prop open subterranean formation fractures. The particles are also useful for water filtration and artificial turf for sports fields. Methods of making the composite particles are also disclosed.
Claims99
A composite particle comprising:
- a substantially homogeneous formed particle comprising:
- a first portion of a binder, wherein the first portion is at least partly cured;
- filler particles dispersed throughout the first portion of binder, wherein particle size of the filler particles ranges from about 0.5 to about 60 μm;
- and
- an optional second portion of a binder coating the formed particle;
- 60-90 volume percent of the composite particle being the filler particles;
- wherein the first and second portions of binder have an absence of cement;
- wherein at least one member of the group consisting of the first portion of binder or the second portion of binder comprises a cold-set resin.
