Abstract

Systems and methods for managing pressures present in an annular space defined between casing strings contained within a subterranean well. These systems and methods may include providing a pressure distribution casing that includes a plurality of pressure distribution passages and distributing fluids present within the annular space along a length of the pressure distribution casing and/or between the annular space and the subterranean formation using a portion of the plurality of pressure distribution passages. Pressure distribution passages may be present on an inner surface of the pressure distribution casing, on an outer surface of the pressure distribution casing, and/or within a wall of the pressure distribution casing and may distribute the fluids along the length of the pressure distribution casing without distributing the fluids across and/or through a wall of the pressure distribution casing, such as between the inner surface and the outer surface of the pressure distribution casing.
