Abstract:
An embodiment of the present invention includes a method of cementing in a subterranean formation comprising: providing an extended settable composition comprising hydraulic cement, cement kiln dust, water, and a set retarding additive, wherein the extended settable composition is capable of remaining in a pumpable fluid state for at least about 1 day; adding a cement set accelerator to the extended settable composition; introducing the extended settable composition into a well bore; and allowing the extended settable composition to set. Another embodiment of the present invention includes a method of cementing in a subterranean formation comprising: providing an extended settable composition comprising hydraulic cement, cement kiln dust, water, and a set retarding additive; storing the extended settable composition; adding a cement set accelerator to the extended settable composition; introducing the extended settable composition into a well bore; and allowing the extended settable composition to set.
