Abstract
Coated particles made of particulate substrates having a coating of resin and fibrous material are provided for use in subterranean formations. The coated substrate particles are proppants useful to prop open subterranean formation fractures. The coated substrate particles are also useful for sand control, that is, acting as a filter or screen to prevent backwards flow of sand, other proppants or subterranean formation particles. Methods of making the coated particles are also disclosed.
