    Abstract: Composiciones de cemento con retardo de fraguado y métodos para utilizar composiciones de cemento con retraso de fraguado en formaciones subterráneas. Las modalidades incluyen un método de perforación de un pozo en una formación subterránea que comprende: hacer circular un fluido de perforación que comprende una composición de cemento con retardo de fraguado en el pozo mientras se perfora el pozo, en donde la composición de cemento con retardo de fraguado comprende: piedra pómez, cal hidratada, un retardante de fraguado, y agua. Un método de desplazamiento de un fluido en un pozo que comprende: introducir un fluido espaciador que comprende una composición de cemento con retardo de fraguado en un pozo de tal manera que el fluido espaciador desplaza uno o más fluidos anteriores del pozo, y en donde la composición de cemento con retardo de fraguado comprende: piedra pómez, cal hidratada, un retardante de fraguado, y agua.

    Abstract: Set-delayed cement compositions and methods of using set-delayed cement compositions in subterranean formations. Embodiments include a method of drilling a wellbore (222) in a subterranean formation comprising: circulating a drilling fluid comprising a set-delayed cement composition in the wellbore (222) while drilling the wellbore (222), wherein the set-delayed cement composition comprises: pumice, hydrated lime, a set retarder, and water. A method of displacing a fluid in a wellbore (222) comprising: introducing a spacer fluid comprising a set-delayed cement composition into a wellbore (222) such that the spacer fluid displaces one or more prior fluids from the wellbore (222), and wherein the set-delayed cement composition comprises: pumice, hydrated lime, a set retarder, and water.

    Abstract: Methods of using the set-delayed cement slurries and compositions resulting from the combination of the set-delayed cement slurries are also described. A method may comprise providing a first set-delayed cement slurry comprising a pozzolanic cement and/or a Portland cement, water, and a first cement set retarder; providing a second set-delayed cement slurry comprising calcium-aluminate and a second cement set retarder; mixing the first slurry and the second slurry to form a cement composition; and allowing the cement composition to set.

    Abstract: Extended-life cement compositions are provided and, more particularly, extended-life cement compositions are provided that comprise a cementitious component comprising red mud solids and hydraulic cement. A method of cementing may comprise providing an extended-life cement composition comprising a cementitious component, water, and a cement set retarder, wherein the cementitious component comprises red mud solids and a hydraulic cement; activating the extended-life cement composition; introducing the extended-life cement composition into a subterranean formation; and allowing the extended-life cement composition to set in the subterranean formation.
