A method comprising: positioning a well tool (100, 550) within a wellbore, the well tool having an initial outer diameter before the well tool is positioned within the wellbore, the well tool comprising: a deformable liner (101, 501); a first inflatable packer (103, 503) positioned within the deformable liner; a second inflatable packer (105, 505) positioned around the deformable liner; an inflation tool (170, 570) coupled to each of the first inflatable packer and the second inflatable packer, independently, the inflation tool configured to convey hydraulic pressure to inflate each of the first inflatable packer and the second inflatable packer, independently; a tubular connection connecting the inflation tool to the second inflatable packer before the well tool is positioned within the wellbore, the tubular connection configured to allow fluid communication between the inflation tool and the second inflatable packer; and a backflow prevention device connected to the tubular connection, the backflow prevention device positioned closer to the second inflatable packer than to the inflation tool, the backflow prevention device configured to allow fluid to flow through the backflow prevention device from the inflation tool to the second inflatable packer and configured to prevent fluid from flowing through the backflow prevention device from the second inflatable packer to the inflation tool, wherein the tubular connection comprises an engineered weak point positioned along the tubular connection closer to the second inflatable packer than to the inflation tool, wherein the tubular connection is configured to break at the engineered weak point in response to an application of tension strain on the tubular connection; inflating the first inflatable packer to deform the deformable liner, such that an inner liner diameter of the deformable liner, after the deformable liner is deformed, is equal to or greater than the initial outer diameter of the well tool; and inflating the second inflatable packer to sealably contact an inner wall of the wellbore. positioning a well tool (100, 550) within a wellbore, the well tool having an initial outer diameter before the well tool is positioned within the wellbore, the well tool comprising: a deformable liner (101, 501);
