Abstract
The present invention relates to composite particulates comprising a base material and a nanoparticle material. One embodiment of the present invention provides a method of using a sintered composite particulate in a subterranean application comprising providing a slurry comprising a sintered composite particulate comprising a base material and at least one nanoparticle material; and placing the slurry into a well bore penetrating a subterranean formation. Another embodiment of the present invention provides sintered composite particulates useful in completing and stimulating wells comprising a base material and nanoparticle material wherein the composite particulate comprises from about 0.1% to about 30% nanoparticle material by weight of the composite particulate and wherein the composite particulates are sintered
