Abstract
A structured composite is comprised of particulates having particle size distribution of at least two modes and a binder. The particle size distribution is preferably bi-modal or tri-modal. The composite may further contain a density-modifying agent for modifying the density of the composite. The particulates are preferably substantially spherical and may be ultra lightweight (ULW) materials. The resulting composites exhibit the requisite strength to survive downhole imposed stresses and temperatures.
