Abstract
A method of servicing a wellbore comprising placing a cement composition comprising a cementitious material, water, and an elastomeric material comprising a bonding polar group into a wellbore, and allowing the cement composition to set to form a set cement, wherein the elastomeric material has a phase transition temperature, exhibits cold flow behavior, or both at less than or equal to the bottom hole static temperature of the wellbore. A method of servicing a cased wellbore penetrating a formation, comprising introducing a self-repairing cementitious material into a wellbore, and allowing the cement to set, wherein upon a loss of structural integrity the set cement self-repairs, and wherein the loss of structural integrity comprises the formation of flow pathways for fluid migration in the cement and self-repair comprises obstructing potential pathways for fluid migration.
