1. An apparatus comprising:
a singular tubular structure that is a continuous cylinder and configured to be positioned inside casing of a wellbore formed in a subsurface formation, wherein the singular tubular structure is configured to expand to contact an inner wall of the casing and provide differential pressure integrity in the wellbore while an isolating component is positioned in the singular tubular structure, and wherein the singular tubular structure includes one or more components formed into an outer face of the singular tubular structure and configured to engage with the inner wall of the casing with the expansion of the singular tubular structure.
