1. A method of stimulating a hydrocarbon well, wherein the hydrocarbon well includes a wellbore that extends within a subterranean formation and a tubular that extends within the wellbore and defines a tubular conduit, the method comprising:
retaining a sealing structure within the tubular conduit to at least partially fluidly isolate an uphole region of the tubular conduit, which is uphole from the sealing structure, from a downhole region of the tubular conduit, which is downhole from the sealing structure;
during the retaining, stimulating a zone of the subterranean formation by providing a stimulant fluid stream to the uphole region and flowing the stimulant fluid stream into the zone of the subterranean formation via a plurality of perforations defined within a portion of the tubular that defines the uphole region;
subsequent to the stimulating, fluidly isolating the zone of the subterranean formation from the uphole region by at least partially sealing the plurality of perforations;
subsequent to the fluidly isolating, moving the sealing structure in a downhole direction within the tubular conduit, wherein the sealing structure is configured to initiate the moving responsive to pressure within a wellbore fluid being less than a threshold move initiation pressure; and
repeating the retaining, the stimulating, the fluidly isolating, and the moving a plurality of times to stimulate a plurality of corresponding zones of the subterranean formation.
