Liner installation with inflatable packer

A method comprising:

• positioning, within a wellbore:
• a deformable liner;
• a first inflatable packer positioned within the deformable liner;
• and
• a second inflatable packer positioned around the deformable liner;
• increasing an inner liner diameter of a deformable liner by inflating the first inflatable packer;
• and
• after increasing the inner liner diameter of the deformable liner, permanently securing the deformable liner within the wellbore by inflating the second inflatable packer.

A well tool comprising:

• a deformable liner configured to be positioned within a wellbore, the deformable liner configured to be deformed radially;
• a first inflatable packer configured to be positioned within the deformable liner, the first inflatable packer configured to be inflated while positioned within the deformable liner to deform the deformable liner radially;
• a second inflatable packer configured to be positioned around the deformable liner, the second inflatable packer configured to be inflated to an inner wall of the wellbore;
• an inflation tool fluidically 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;
• 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.
