Abstract
A method of cementing a wellbore comprises combining an alginate suspension additive with a cement slurry to form a cementing composition, the cement slurry comprising an aqueous carrier and a cementitious component; injecting the cementing composition into the wellbore; and allowing the cement composition to set.
Claims14
A method of cementing a wellbore, the method comprising:
- combining an alginate suspension additive with a cement slurry to form a cement composition, the cement slurry comprising about 10 wt. % to about 60 wt. % of an aqueous carrier and about 60 wt. % to about 90 wt. % of a cementitious component, each based on the total weight of the cement slurry;
- injecting the cement composition into the wellbore;
- and
- allowing the cement composition to set,
- wherein the alginate suspension additive is added in an amount of about 0.01 wt. % to about 5 wt. % based on the weight of the aqueous carrier in the cement slurry.
