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 are realized by adding the polyamide to the cement composition.
