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.
