Abstract

Lithium-containing cement admixtures including a calcium aluminate phosphate cement; a lithium-ion-containing compound; and an aqueous base fluid and methods of introducing the lithium-containing cement admixtures into a subterranean formation. The lithium-containing cement admixtures may further comprise an aluminosilicate or an additive including a set retarder, a set accelerator, a suspension aid, a density reducing agent, a fluid loss control agent, a defoamer, and any combination thereof.

Claims

1. A method comprising:

providing a lithium-containing cement admixture (“

LCCA”

) comprising a calcium aluminate phosphate cement, a lithium-ion containing compound, and an aqueous base fluid;

introducing the LCCA into a subterranean formation.

2. The method of claim 1, wherein the LCCA has a pump time of between about 90 min to about 1000 min.

3. The method of claim 1, further comprising forming a hydrated cement in at least a portion of the subterranean formation, the hydrated cement having a compressive strength of between about 50 psi to about 5000 psi in about 24 hours.

4. The method of claim 1, wherein the calcium aluminate phosphate cement has a calcium aluminate content in the range of about 20% to about 80% by weight of the calcium aluminate phosphate cement.

6. The method of claim 1, wherein the calcium aluminate phosphate cement is present in an amount in the range of about 1% to about 99.99% by weight of the LCCA.

7. The method of claim 1, wherein the lithium-ion containing compound is present in an amount in the range of about 0.1% to about 10% by weight of the calcium aluminate phosphate cement.

8. The method of claim 1, wherein the aqueous base fluid is present in an amount in the range of about 20% to about 80% by weight of the calcium aluminate phosphate cement.

9. The method of claim 1, wherein the lithium-ion-containing compound is a lithium salt.
