Wellbore annulus seal system

A method for sealing a wellbore annulus, the method comprising:

• mounting, with a first fastener, a top holding plate of an annular isolation system to a first tubing disposed in a wellbore, the annular isolation system comprising:
• a bottom holding plate having an annular shape and comprising a first surface,
• a seal element having an annular shape and disposed on the first surface of the bottom holding plate,
• a torque plate disposed on the seal element and positioned opposite to the bottom holding plate, the torque plate comprising an annular shape, wherein the seal element is positioned between the bottom holding plate and the torque plate, and
• a top holding plate connected to the bottom holding plate and comprising an adjustment mechanism engaged with the torque plate;
• moving the torque plate, with the adjustment mechanism, in a downhole direction;
• in response to moving the torque plate in the downhole direction, compressing the seal element between the torque plate and the bottom holding plate;
• and
• sealing, with the seal element, an annulus between the first tubing and a casing disposed in the wellbore.

An annulus seal system, comprising:

• an annular isolation system configured to connect to a tubing disposed in a wellbore, the annular isolation system comprising:
• a bottom holding plate having an annular shape and comprising a first surface,
• a seal element having an annular shape and disposed on the first surface of the bottom holding plate, the seal element configured to expand in a radial direction,
• a torque plate disposed on the seal element and positioned opposite to the bottom holding plate, the torque plate comprising an annular shape, wherein the seal element is positioned between the bottom holding plate and the torque plate, the torque plate configured to move in a longitudinal direction to compress the seal element between the bottom holding plate and the torque plate, and
• a top holding plate connected to the bottom holding plate and comprising an adjustment mechanism engaged with the torque plate, the adjustment mechanism configured to control movement of the torque plate in the longitudinal direction.
