Abstract:
A method includes positioning a casing into a wellbore. Cement is pumped through the casing to cement the casing in the wellbore. A casing hanger is positioned within a casing head spool that is part of a surface wellhead assembly at an uphole end of the wellbore. The casing hanger is attached to an uphole end of the casing. A production tubing string including a plurality of production tubing segments is positioned within the casing within the wellbore. An uphole end of the production tubing string is attached to a lower end of a rotating inner mandrel of a production tubing hanger. The production tubing hanger is configured be positioned within a tubing head spool positioned above the casing head spool within the surface wellhead assembly. The rotating inner mandrel is configured to rotate within a non-rotating housing of the production tubing hanger. The production tubing string is rotated by rotating a landing joint including a production tubing segment attached to an upper end of the rotating inner mandrel. While rotating the production tubing string, cement is pumped through the production tubing string to at least partially cement the production tubing string within the wellbore.
