摘要： Methods of using density-reducing additives comprising low-density particulates in subterranean cementing operations are provided. In one embodiment, the present invention provides a method of cementing comprising: providing a cement composition comprising a cement component, a base fluid, and a density-reducing additive comprising particulates that comprise an agglomerating material; placing the cement composition in a location to be cemented; and allowing the cement composition to set therein.
