Abstract
The invention is an adjustable tubing hanger for suspending a tubular string from a wellhead. The adjustable tubing hanger has an upper body having a seal, a lower body attached to the upper body and the tubular string, a carrier assembly located between the upper body and the lower body providing at least one metal seal for an annulus, and a drive lock assembly attached to the lower body with a tension lock and numerous segments. Each segment has an outer diameter with a grooved profile forming a load bearing interlock for the drive lock assembly. The tension on the tubular string is adjustable depending on adjustments made to the interlock position of the grooved profile.
