Abstract
A well, well head, drilling and completion system, and method for relieving pressure buildup between concentric casing annuli. The well head includes casing hangers and a tubing hanger that may include annular pressure relief conduits formed therein, which selectively vent casing annuli to the interior of the production tubing. Annular pressure relief valves are located within the annular pressure relief conduits, which may open and/or shut based on pressure, temperature, or elapsed time.
