Dual Seal Tubing Hanger

Abstract

A dual seal system and related method seal a tubing hanger. In an embodiment, a dual seal tubing hanger includes a hanger body. The dual seal tubing hanger also includes an upper body seal and an upper body seal ring. The upper body seal is disposed between the hanger body and the upper body seal ring. In addition, the dual seal tubing hanger includes a lower body seal and a lower body seal ring. The lower body seal is disposed between the lower body seal ring and the hanger body. The upper body seal and the upper body seal ring are disposed on an opposing end of the hanger body from the lower body seal and the lower body seal ring.

1 . A method for providing dual seals to a tubing hanger to provide a dual seal tubing hanger, wherein the tubing hanger comprises an upper body seal ring, an upper body seal, a lower body seal, and a lower body seal ring, comprising:
 (A) moving the upper body seal ring relative to a longitudinal axis of the tubing hanger;   (B) compressing the upper body seal to form an upper seal, wherein movement of the upper body seal ring compresses the upper body seal;   (C) moving the lower body seal ring relative to the longitudinal axis of the tubing hanger; and   (D) compressing the lower body seal to form a lower seal, wherein movement of the lower body seal ring compresses the lower body seal.   
     
     
         2 . The method of  claim 1 , further comprising contacting the upper body seal ring with a portion of a tubing spool to move the upper body seal ring. 
     
     
         3 . The method of  claim 2 , wherein the upper body seal ring comprises an upper body slanted side, and wherein the portion of the tubing spool contacts the upper body slanted side. 
     
     
         4 . The method of  claim 1 , wherein the tubing hanger comprises a lower extended portion, and wherein the method further comprises attaching tubing to the lower extended portion to actuate movement of the lower body seal ring. 
     
     
         5 . The method of  claim 4 , wherein the tubing comprises a weight, and wherein the weight of the tubing actuates movement of the lower body seal ring.
