Abstract
Cementing in a subterranean formation may include, activating an extended-life cement composition by mixing at least the extended-life cement composition with a liquid activated pozzolan additive comprising a carrier fluid and an activated pozzolan, wherein the extended-life cement composition comprises water, pumice, hydrated lime, and a set retarder; introducing the extended-life cement composition into a subterranean formation; and allowing the extended-life cement composition to set to form a hardened mass in the subterranean formation.
Claims20
A method of cementing in a subterranean formation, comprising:
- activating an extended-life cement composition by mixing at least the extended-life cement composition with a liquid activated pozzolan additive comprising a carrier fluid and an activated pozzolan, wherein the activated pozzolan comprises cement hydration products deposited on a pozzolan, and wherein the cement hydration products are reaction products of water and at least one cement, wherein the extended-life cement composition comprises water, pumice, hydrated lime, and a set retarder;
- introducing the extended-life cement composition into a subterranean formation;
- and
- allowing the extended-life cement composition to set to form a hardened mass in the subterranean formation.
