Abstract:
A method of mitigating annular pressure buildup includes providing or using a foamed treatment fluid including: an aqueous base fluid; a water-soluble polymer comprising carbonyl groups; an organic crosslinking agent that comprises an amine group that is capable of crosslinking the water-soluble polymer comprising carbonyl groups; a foam surfactant; and sufficient gas to form a foam; and introducing the foamed treatment fluid into a well bore annulus. A foamed treatment fluid includes an aqueous base fluid; a water-soluble polymer comprising carbonyl groups; an organic crosslinking agent that comprises an amine group that is capable of crosslinking the water-soluble polymer comprising carbonyl groups; a foam surfactant; and sufficient gas to form a foam.
