Cement having cross-linked polymers |
abstract |
A composition and method of forming a wellbore cement that includes a cross-linked polyamide. The polyamide is formed by reacting a di-functional amine with an aromatic trifunctional 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. |
