Claim:
1. A subterranean well configured to provide a hydraulic connection between a surface region and a subterranean formation that includes a reservoir containing a reservoir fluid, wherein the subterranean well includes a wellbore that extends between the surface region and the subterranean formation, the subterranean well comprising: a pressure distribution casing string contained within the wellbore, wherein the pressure distribution casing string includes a plurality of casing sections operatively attached to one another along a longitudinal axis, wherein at least one of the plurality of casing sections is a pressure distribution casing adapted to distribute fluid within the subterranean well and the pressure distribution casing comprising; at least one additional conduit; wherein at least a portion of at least one of the pressure distribution casing string and the at least one additional conduit is concentrically contained within at least a portion of the other of the pressure distribution casing string and the at least one additional conduit to define an annular space; wherein at least one of the plurality of pressure distribution passages fluidly connects the annular space with a casing shoe on at least one of the pressure distribution casing and the at least one additional conduit such that the annulus may be in fluid communication along the wellbore longitudinal axis with at least a portion of the subterranean formation; and wherein the plurality of pressure distribution passages do not connect the casing body internal passage with the annular space.
