The present invention provides reduced-density coated particulates and
methods for enhancing the transport of such particulates into well bores
and fractures, and for enhancing the conductivity and permeability of
subterranean formations using such particulates, and for sand control
treatments using such particulates. The reduced-density, coated
particulates of the present invention generally comprise particulate
having a surface and a coating wherein the surface comprises a porous or
partially hollow geometry and coating is capable of trapping a fluid
between the particulate's surface and the coating.
