Abstract: A system for deploying a fabric liner in a wellbore includes a free-to-fall sub and a shoe track. The free-to-fall sub includes a weighted compartment that is filled with a first fluid that increases the weight of the free-to-fall sub and at least one stabilizing wheel that centralizes the free-to-fall sub within the wellbore. The shoe track incudes a plurality of orifices that release a second fluid into the fabric liner. The fabric liner retains the second fluid between the shoe track and the fabric liner. The free-to-fall sub is rigidly fixed to a downhole end of the fabric liner such that the fabric liner supports the free-to-fall sub within the wellbore.

Abstract: A rotational continuous circulation system and methods includes a circulation sub having an internal bore extending along a central axis. The circulation sub has an uphole body having a reduced outer diameter along a downhole length of the uphole body. A central valve selectively opens and closes the uphole internal bore. At least one check valve is located within a sidewall of the uphole body to selectively allow fluid to flow into the uphole internal bore through the at least one check valve. A downhole body has an uphole portion circumscribing a downhole portion of the uphole body. A sleeve assembly circumscribes the reduced outer diameter of the uphole body. The uphole body and the downhole body are configured to rotate about the central axis independently from the sleeve assembly. A side-entry port of the sleeve assembly provides a fluid flow path from an exterior of the sleeve assembly to the at least one check valve.
