Abstract
A test cell for testing a sample cement composition includes a test chamber and a variable stress system. The test chamber is configured to hold a sample cement composition for a wellbore. The variable stress system communicates with the test chamber. Performance of the sample cement composition is tested for a wellbore using the variable stress system.
