Abstract
A wellbore cement composition that includes a cross-linked polyamide. The polyamide is formed by reacting a di-functional amine with an aromatic tri-functional carboxylic acid. The wellbore cement composition is created by blending cement and water with the polyamide and then allowed to cure. Increases in compressive strength, Young's Modulus, and Poisson's Ratio of the cement were realized by adding the polyamide to the cement composition.
Claims3
A cement composition for use in a wellbore comprising:
- a cement;
- a calcium silicate in the cement;
- and
- a polyaramide condensate compound that is cross-linked and formed from a trifunctional carboxylic acid and a diamine, where the polyaramide comprises poly(hexamethylene-co-sebacoyl trimesoylamide).
