Abstract:
Compositions and methods that mitigate pressure buildup in the annular space between two tubular bodies in subterranean wells. The composition comprises an aqueous solution of crosslinkable polymer, a crosslinker and a gas. Once foamed and placed in the annular space, the composition provides a resilient, flexible, compressible and durable body that is able to compensate for pressure increases in the annular space, thereby protecting the integrity of the tubular bodies.
