Systems and methods for providing and energizing a seal gland assembly on a valve in a tubing hanger are described. A seal gland assembly comprising a first seal, a second seal, and a third seal is provided in a seal gap formed longitudinally between a spacer and a seal prep of tubing hanger threads and laterally between a bore wall of the tubing hanger and a sidewall of the valve. As the valve is threaded into the tubing hanger, the seal prep of the tubing hanger presses the first seal into the second seal, the second seal is then pressed into the third seal, pressing the third seal against the spacer compressing the first seal, the second seal, and the third seal approximately filling the seal gap.

Seal gland assembly for a valve in a tubing hanger

A sealing system () that includes a first component (), a second component () and a polymer seal () positioned in a seal recess () in the first component. A TWSMA member () is positioned in the seal recess (), wherein the TWSMA member () has a retracted shape (R) and an expanded shape (E), the TWSMA member () transitioning from the retracted shape (R) to the expanded shape (E) at a temperature that is less than an installation temperature when the polymer seal () and the TWSMA member () were positioned in the seal recess (). In the expanded shape (E) the TWSMA member () exerts a force () on the polymer seal () so as to urge the polymer seal () into sealing contact with the second component () and wherein in the expanded shape (E), at least a portion (S) of a surface (S) of the TWSMA member () is positioned at a location that is farther away from a surface (A,X) of the seal recess () that the portion (S) was when the TWSMA member () was in its retracted shape (R).

Shape memory alloy member for use in polymer or composite seal applications

A measurement device is disclosed which includes a structure adapted to be removably coupled to a Christmas tree, a sleeve operatively coupled to the structure and a flowmeter positioned at least partially within the sleeve.
