A cementing composition which is capable of self-sealing cracks in the cement composition is provided. For example, the composition includes a polymer that is swellable in the presence of gaseous hydrocarbons, hydrogen sulfide, carbon dioxide, carbonic acid and/or hydrochloric acid. A method for using the cementing composition in cementing operations for wellbore through a subterranean formation is also provided. |
