Abstract
A crooked slanted cased wellbore extends downhole to a pay zone which is produced by a rod actuated downhole pump that lifts fluid from the bottom of the wellbore up through a tubing string to a wellhead. The pump is seated in a pump cavity and the tubing string is tensioned at opposed ends while it is rotated.
The upper end of the tubing string is attached to a fluid conveying swivel means and a tubing rotator. A tubing anchor having a fluid conveying rotatable mandrel is attached adjacent to and forms part of the lower end of the tubing string by which the lower end of the tubing string is rotatably tensioned and releasably affixed to the casing in proximity to the lower end of the wellbore. A plurality of radially active slips are actuated in response to manipulation of the tubing string to extend the slips into engagement with the casing wall and to retract the slips in order to remove the tubing string from the borehole.
