摘要：
The present invention is embodied in systems and methods for mitigating temperature-related pressure buildup in the trapped annulus of an oil or gas well, wherein such systems and methods employ production and/or tieback casing having one or more pressure mitigating chambers, and wherein such chambers make use of pistons, valves, and burst disks to mitigate pressure increases within the annulus.
