System and method for running and cementing fabric-nested casing

A well system, comprising:

• a first casing string extending a first depth within a wellbore, wherein the first casing string comprises a first plurality of casing joints joined end-to-end;
• a first cement slurry configured to cement the first casing string within the wellbore;
• a second casing string extending a second depth within a wellbore, wherein the second casing string comprises a second plurality of casing joints joined end-to-end, wherein the second depth is deeper than the first depth;
• a fabric sheet nesting a length of the second casing string;
• and
• a second cement slurry provided in a space between the fabric sheet and the length of the second casing string configured to inflate the fabric sheet against the wellbore and cement the length of the second casing string within the wellbore.

A method, comprising:

• attaching a pre-cut center hole of a fabric sheet to a sleeve on a modified float joint of a casing string;
• lowering the casing string into a wellbore;
• closing, with a union unit, the fabric sheet around the casing string as the casing string is being lowered into the wellbore to form a fabric-nested casing string;
• cutting the fabric sheet based on a length of the casing string to be nested by the fabric sheet distal to the modified float joint;
• performing cementing operations when the casing string reaches a bottom of the wellbore;
• pumping a first plug down the casing string ahead of a cement slurry to land within the modified float joint;
• increasing a pressure within the modified float joint by continuously pumping the cement slurry;
• opening one or more side ports of the modified float joint when the pressure reached a threshold;
• and
• inflating the fabric sheet with the cement slurry by flowing the cement slurry through the one or more side ports into a space between the fabric sheet and the modified float joint, wherein the fabric sheet is inflated against the wellbore to cement the casing string.
