Abstract

A variety of methods and compositions for cementing with set-delayed cement. In one embodiment a method comprises providing a set-delayed cement composition comprising a hydraulic cement, water, and a primary retarder. The method further comprises activating the set-delayed cement composition through a retarder exchange whereby, a secondary retarder is added to the set-delayed cement composition to produce an activated cement composition. The activated cement composition is then allowed to set.
