Abstract
Methods and compositions useful for subterranean formation treatments, such as hydraulic fracturing treatments and sand control that utilize relatively lightweight and/or substantially neutrally buoyant particulates. Particles that may be employed include particulates of naturally occurring materials that may be optionally strengthened or hardened by exposure to a modifying agent; porous materials including selectively configured porous material particles manufactured and/or treated with selected glazing materials, coating materials and/or penetrating materials; and well treating aggregates composed of an organic lightweight material and a weight modifying agent. The relatively lightweight particulate may be suspended as a substantially neutral buoyant particulate and stored with a carrier fluid as a pumpable slurry.
