Abstract
A composition for use as a latex cement additive, the composition comprising an aqueous latex, the aqueous latex comprising an aqueous fluid and a solid elastomer, where the solid elastomer is dispersed in the aqueous fluid; a liquid elastomer, the liquid elastomer having a viscosity between 50,000 cP and 300,000 cP at room temperature; and a surfactant, the surfactant operable to facilitate incorporation of the liquid elastomer into the aqueous latex.
Claims15
A method of using a cement slurry composition in a downhole application in a wellbore, the method comprising the steps of:
- adding an amount of a liquid elastomer to an aqueous latex to produce a latex cement additive;
- mixing the latex cement additive, such that the liquid elastomer forms a dispersed phase in the aqueous fluid;
- adding an amount of the latex cement additive to a cement composition;
- mixing the latex cement additive into the cement composition to form the cement slurry composition;
- introducing the cement slurry composition to the wellbore in the downhole application;
- and
- allowing the cement slurry composition to harden into a set cement.
