Abstract
The present disclosure relates to a method of cementing comprising: providing a cement composition comprising: water, a cement, and a non-aqueous liquid anti-shrinkage cement additive comprising calcined magnesium oxide and a non-aqueous liquid; introducing the cement composition into a subterranean formation; and allowing the cement composition to set in the subterranean formation. Non-aqueous liquid anti-shrinkage cement additives, cement compositions, and systems are also provided.
Claims8
A method of cementing comprising:
- providing a non-aqueous liquid anti-shrinkage cement additive comprising:
- calcined magnesium oxide;
- and
- a non-aqueous liquid comprising a hydrocarbon liquid;
- and
- combining water, a cement, and the non-aqueous liquid anti-shrinkage cement additive to form a cement composition;
- introducing the cement composition into a subterranean formation;
- and
- allowing the cement composition to set in the subterranean formation.
A system for cementing in a subterranean formation comprising:
- a non-aqueous liquid anti-shrinkage cement additive comprising:
- calcined magnesium oxide;
- a non-aqueous liquid comprising a hydrocarbon liquid;
- and
- mixing equipment capable of mixing the non-aqueous anti-shrinkage cement additive with a cement and water to form a cement composition;
- and
- pumping equipment capable of delivering the cement composition into a wellbore.
