Abstract
Systems and methods for improving functional access to subterranean formations that include a well, which includes a casing string having at least one casing conduit that extends and provides a hydraulic connection between a surface region and the subterranean formation. Performing a plurality of downhole operations utilizing a casing string that constitutes a plurality of hydraulic pathways between the surface region and the subterranean formation. The plurality of downhole operations may be simultaneous operations and/or may be associated with at least one of a plurality of operational states including a drilling state, completing state, stimulating state, producing state, abandoning state, and/or killing state. In some embodiments, systems and methods may include a plurality of production control assemblies to control and/or monitor the downhole operations.
