Title (EN) CEMENT COMPOSITIONS COMPRISING STRENGTH-ENHANCING LOST CIRCULATION MATERIALS AND METHODS OF CEMENTING IN SUBTERRANEAN FORMATIONS
(FR) COMPOSITIONS DE CIMENT COMPRENANT DES COLMATANTS RENFORÇANT LA RESISTANCE ET METHODES DE CIMENTATION DANS DES FORMATIONS SOUTERRAINES
Abstract:
(EN) The present invention provides cement compositions comprising a strength-enhancing lost circulation material, and methods for cementing using such cement compositions. Exemplary embodiments of the cement compositions comprise cement, water, and a strength-enhancing lost circulation material. Optionally, other additives suitable for inclusion in cement compositions may be added.
(FR) L'invention concerne des compositions de ciment comprenant un colmatant renforçant la résistance, ainsi que des méthodes de cimentation utilisant lesdites compositions de ciment. Des exemples de modes de réalisation desdites compositions de ciment comprennent du ciment, de l'eau et un colmatant renforçant la résistance. D'autres additifs convenant à une intégration dans des compositions de ciment peuvent éventuellement être ajoutés.
