1. A well completion system for producing fluids from a reservoir via a wellbore provided in the reservoir, comprising:
a tubing string extending along the wellbore and comprising:
an injection segment comprising:
an injection valve including an injection valve housing defining an injection fluid passage allowing injection fluid to flow through the housing, and an injection port for establishing fluid communication with the surrounding reservoir to enable injection of injection fluid within the reservoir, the injection valve comprising:
a flow restriction component configured to restrict fluid flow between the injection fluid passage and the injection port; and
a breakable barrier installed within the injection port, the breakable barrier being fluid-activated to operate the injection valve between a closed configuration where the breakable barrier occludes the injection port for preventing fluid flow into the reservoir, and an open configuration where the breakable barrier is at least partially removed from within the injection port for allowing fluid flow into the reservoir;
a production segment comprising:
a tubular housing defining a production fluid passage therethrough allowing production fluid to flow through the housing, and having a production port for establishing fluid communication between the production fluid passage and the surrounding reservoir to enable flow of production fluid from the reservoir into the production fluid passage, the tubular housing further including injection fluid passageways allowing injection fluid to flow through the production segment;
one or more injection conduits coupled to the injection and production segments, and being adapted to allow injection fluid to flow along the wellbore through at least one injection or production segment, each injection conduit being in fluid communication with the injection fluid passage;
one or more production conduits coupled to the injection and production segments, and being adapted to allow production fluid to flow along the wellbore through at least one injection or production segment, each production conduit being in fluid communication with the production fluid passage; and
a connection segment comprising:
an injection coupling adapted to connect the injection conduit to one of another injection conduit and the injection valve housing; and
a production coupling engaged with the injection coupling and configured to connect the production conduit to one of another production conduit and the tubular housing of the production segment, the production coupling comprising a conduit stabilizer configured to position the production coupling relative to the injection coupling in order to position the production conduit relative to the injection conduit.
