    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 (20); and allowing the extended-life cement composition to set in the subterranean formation.

    Abstract: Methods of using extended-life cement compositions are disclosed. A method comprises providing an extended-life cement composition comprising calcium-aluminate cement, water, and a cement set retarder. The method additionally comprises mixing the extended-life cement composition with a cement set activator to activate the extended-life cement composition. The method further comprises Introducing the activated extended-life cement composition into a subterranean formation and allowing the activated extended-life cement composition to set in the subterranean formation; wherein the activated extended-life cement composition has a thickening time of greater than about two hours. The most suitable drawing: FIG. 3.

    Abstract: A method of treating a subterranean formation comprising: introducing a first cement composition into the subterranean formation, wherein the first cement composition comprises: (A) a first aluminate cement; and (B) a base fluid; simultaneously introducing a second cement composition into the subterranean formation, wherein the second cement composition comprises: (A) a second cement consisting of cement or a pozzolan; and (B) a base fluid, wherein at least a portion of the first and second cement compositions mix together after introduction into the subterranean formation to form a mixed cement composition, and wherein at least some of the first and second cement compositions or at least some of the mixed cement composition enters into a highly-permeable area located within the subterranean formation; and allowing the mixed cement composition to set. The base fluid can be an aqueous liquid or a hydrocarbon liquid.
