Abstract:
Methods, compositions, and systems for cementing are included. The method comprises providing an extended-life calcium aluminophosphate cement composition comprising calcium aluminate cement, a polyphosphate, water, and a cement set retarder. The method further comprises mixing the extended-life calcium aluminophosphate cement composition with a cement set activator to activate the extended-life calcium aluminophosphate cement composition, introducing the activated extended-life calcium aluminophosphate cement composition into a subterranean formation, and allowing the activated extended-life calcium aluminophosphate cement composition to set in the subterranean formation.
