ABSTRACT:
Foamed cement compositions comprising density reducing additives and methods of making and using the same are disclosed. In one embodiment, a method of cementing is disclosed. The method of cementing comprises preparing a base cement composition comprising a cement, a water, and a density reducing additive, wherein the base cement composition comprises a base density. The method further comprises introducing a gas to the base cement composition to provide a cement composition having a density less than the base density and allowing the cement composition to set.
