Flexible durable cement
According to at least one embodiment of the present description, a cement slurry includes 50% to 90% BWOC of a cement precursor material based on a total weight of the cement slurry; and from 10% to 50% BWOC of a flexible additive based on the total weight of the cement slurry. The flexible additive includes hydrophilic polyolefin fibers or 2,6-di-tert-butyl-p-cresol.
1. A cement slurry comprising:
50% to 90% BWOC of a cement precursor material based on a total weight of the cement slurry;
from 10% to 50% BWOC of a flexible additive based on the total weight of the cement slurry; and
water,
where the flexible additive comprises 2,6-di-tert-butyl-p-cresol.
2. The cement slurry of claim 1 , where the flexible additive consists essentially of 2,6-di-tert-butyl-p-cresol.
3. The cement slurry of claim 1 , where the flexible additive has a density from 1000 kg/m 3 to 1700 kg/m 3 .
4. The cement slurry of claim 1 , where the flexible additive has a specific gravity from 2.0 to 3.0.
5. The cement slurry of claim 1 , where the cement slurry comprises from 10% to 30% BWOC of the flexible additive based on the total weight of the cement slurry.
