Multiple tubing annuli pipeline systems and methods

Abstract

Techniques for implementing a pipe segment that includes a tubing inner barrier layer that defines a pipe bore through the pipe segment, a venting tubing annulus implemented around the tubing inner barrier layer, in which the venting tubing annulus includes a first solid material implemented to define a venting fluid conduit, a tubing intermediate barrier layer implemented around the venting tubing annulus, a reinforcement tubing annulus implemented around the tubing intermediate barrier layer, and a tubing outer barrier layer implemented around the reinforcement tubing annulus. The reinforcement tubing annulus includes a second solid material that is different from the first solid material and is implemented to define a reinforcement fluid conduit. Additionally, the venting fluid conduit facilitates venting fluid that permeates from the pipe bore through the tubing inner barrier layer out from the pipe segment before the fluid contacts the second solid material in the reinforcement tubing annulus.
