Abstract: There is described a method of rotatably connecting the downhole end of a tubing string to a tubing anchor in a well bore, the method comprising the steps of connecting the downhole end of the tubing string to a first tubular sub, connecting the tubing anchor to a second tubular sub, providing an initial connection between the first and second tubular subs preventing both relative rotation and axial separation therebetween, fixing the tubing anchor in place in the well bore by means of torque transmitted through the tubing string and the first and second tubular subs to the tubing anchor, and rupturing the initial connection between the first and second tubular subs by means of tension applied to the first tubular sub, whereupon the first and second tubular subs may be axially separated by a predetermined amount so that one can rotate relative to the other and so that the tubing string is then rotatable relative to the tubing anchor.

Abstract: There is described a method and an improved apparatus for rotatably suspending a tubing string in a well bore, the apparatus comprising a tubular coupler connected to the uphole end of the tubing string, a tubing hanger disposed annularly about the coupler in fixed axial relationship, the coupler being rotatable relative to the hanger, a hanger bowl for supporting the hanger therein so that the tubing string connected to the coupler can be suspended in the well bore and a drive system operably connected to the coupler and extending through the hanger bowl which can be actuated to rotate the coupler and hence the tubing string attached thereto.

Abstract: Described is a clutch for providing a rotatable connection between the downhole end of a tubing string and a tubing anchor comprising first and second tubular subs and a connector device between the tubular subs, the connector device initially preventing relative rotation between the tubular subs and thereafter permitting relative rotation.
