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.

Claim (Index 20):
The method of  claim 19 , wherein the foam surfactant comprises at least one selected from the group consisting of betaines, sultaines, and imidazolinium, SLS, polyoxyethylene fatty alcohols, polyoxyethylene sorbitol esters, alkanolamides, sulfosuccinates, phospholipids, glycolipid, sodium lauryl sulfoacetate, alcohol ether sulfates, and combinations thereof.
