Abstract: An annulus seal system includes a retention plate mounted to a tubing in a wellbore at an uphole longitudinal end of the tubing and an annular isolation system coupled to the retention plate. The annular isolation system includes a bottom holding plate positioned in an annulus between two tubings, a seal element residing on the bottom holding plate to seal the annulus between the tubings, a torque plate, and a top holding plate. The seal element is positioned between the bottom holding plate and the torque plate, and the torque plate moves in a longitudinal direction toward the bottom holding plate to compress the seal element between the bottom holding plate and the torque plate. The top holding plate mounts to the retention plate, and includes an adjustment mechanism engaged with the torque plate to control movement of the torque plate in the longitudinal direction.

Abstract: A tubing hanger assembly for use in a wellhead assembly that includes tubing hanger member, a retainer that lands in the hanger member, and slip assembly landed in the retainer that supports a string of composite tubing and an electrical submersible pump assembly (ESP). The tubing and ESP are disposed in a wellbore formed beneath the wellhead assembly. The slip assembly is non-marking and includes grit on its inner surface rather than teeth.
