Beschreibung
Zusammenfassung:	A method of cementing in a subterranean formation that comprises providing a foamed cement composition that comprises water, a cement, a gas, and an additive, the additive comprising an anionic foaming agent and at least one of an anionic foam stabilizer or a Zwitterionic foam booster; placing the cement composition into the subterranean formation; and allowing the cement composition to set therein is provided. Foamed cement compositions, additives for foaming and stabilizing a cement composition, and methods of reducing the density of a cement composition, also are provided. L'invention concerne un procédé de cimentation de formation souterraine qui consiste à fournir une composition de ciment expansé renfermant de l'eau, un ciment, du gaz et un additif, lequel renferme un moussant anionique et au moins un stabilisateur de mousse anionique ou un renforçateur de mousse zwittérionique ; à placer la composition de ciment dan la formation ; et à laisser prendre la composition. On décrit aussi des compositions de ciment expansé, des additifs pour le moussage et la stabilisation d'une composition de ciment, et des procédés de réduction de la densité d'une composition de ciment.
