Abstract
The present disclosure relates to a liquid agent that mitigates shrinkage of cement, particularly cement used in a hydrocarbon-producing well. The anti-shrinkage agent includes a slow-setting calcium aluminate cement as well as gypsum and may exhibit shelf-life stability, physical stability, or both. The present disclosure further relates to methods of cementing a hydrocarbon-producing well using the anti-shrinkage agent and to cements containing the anti-shrinkage agent.
