Abstract
Described herein are systems and methods for sealing a well with multiple annuli. In an example, a downhole assembly can be lowered into a cavity of a production tube. Openings can be created in the production tube and an inner casing. The downhole assembly can create a seal between the production tube and the inner casing that allows barrier fluid to freely flow into an outer annular gap between the inner casing and an outer casing. A barrier fluid can be injected such that the barrier fluid flows through the radial openings into the outer annular gap.
