MITIGATION OF CONTAMINATION EFFECTS IN SET-DELAYED CEMENT COMPOSITIONS COMPRISING PUMICE AND HYDRATED LIME

摘要

Methods and compositions for cementing are disclosed. Embodiments include a method of cementing comprising: providing a set-delayed cement composition comprising water, pumice, hydrated lime, a primary set retarder, a secondary set retarder; activating the set-delayed cement composition to produce an activated cement composition; introducing the activated cement composition into a subterranean formation; and allowing the activated cement composition to set in the subterranean formation.
