Title (EN) METHODS OF CEMENTING WITH LIGHTWEIGHT CEMENT COMPOSITIONS
(FR) PROCEDES DE CIMENTATION UTILISANT DES COMPOSITIONS DE CIMENT LEGER
Abstract: front page image
(EN)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.
(FR)La présente invention concerne des compositions de ciment cellulaire comprenant des additifs réducteurs de densité et des procédés de production et d'utilisation de ces compositions. Dans un mode de réalisation, cette invention concerne un procédé de cimentation. Ce procédé de cimentation consiste à préparer une composition de ciment de base comprenant du ciment, de l'eau et un additif réducteur de densité, laquelle composition de ciment de base présente une densité de base. Le procédé consiste ensuite à introduire un gaz dans la composition de ciment de base afin d'obtenir une composition de ciment présentant une densité inférieure à la densité de base puis à laisser prendre la composition de ciment.
