Abstract: A tubing hanger assembly for suspending a tubing string within a wellbore is provided. The tubing hanger assembly comprises a tubing head, a tubing hanger and a tubing head adapter. The tubing hanger and the tubing head adapter have aligned through-openings such that a chemical injection line and a communications line may each be passed through respective through-openings, thereby enabling an operator to have access to the wellbore. Beneficially, the assembly also comprises a bottom flange that secures the tubing head adapter to the tubing head once the tubing hanger and connected string of production tubing are landed in the wellbore. The bottom flange may be rotated so that ports in the bottom flange may be aligned with ports in an upper flange in the tubing head. A method for hanging a string of production tubing in a wellbore is also provided herein.

Abstract: A tubing hanger system for suspending a tubing string within a wellbore is provided. The system is designed to place the tubing string in tension. The tubing hanger system comprises a tubing hanger and a tubing anchor. Both the tubing hanger and the tubing anchor are designed to reside in series with the production tubing. The tubing hanger is threadedly connected to the tubing string at the top of the wellbore. The tubing anchor is also threadedly connected to the tubing string but is configured to be set within a string of casing downhole. Beneficially, the tubing hanger and the tubing anchor is each uniquely configured to be set through a rotation of the tubing string that is less than one full rotation. This enables use of a stainless steel chemical injection line extending from the tubing hanger to the tubing anchor. A method for hanging a string of production tubing in a wellbore, in tension, is also provided herein.
