Abstract
A subsea completion system can include a lower completion assembly (LCA) having a receptacle disposed at a top end of the LCA, where the LCA comprises a LCA wall that forms a LCA cavity; a first barrier disposed within the LCA cavity, where the first barrier forms a first fluidic seal with the LCA wall, and where the first barrier is configured to open when a first differential force within the LCA cavity reaches a first threshold value; an upper completion assembly (UCA) having a tubing string that includes a tubing string wall that forms a tubing string cavity; and a second barrier disposed within the tubing string cavity, where the second barrier forms a second fluidic seal with the tubing string wall, and where the second barrier is configured to open when a second differential force within the tubing string cavity reaches a second threshold value.
