Shunt system with shroud secured by a locking member

An apparatus adapted to be disposed within a wellbore, the apparatus comprising:

• a support member;
• a groove formed into the support member;
• a key disposed at least partially within the groove;
• a tubular sliding member adapted to be displaced longitudinally relative to the support member into a locking position, in which the tubular sliding member is disposed about the support member;
• and
• a cavity formed into the tubular sliding member and adapted to receive the key when the tubular sliding member is in the locking position;
• wherein the key is disposed within both the groove and the cavity to secure the tubular sliding member in the locking position.

A method for making-up a connection between first and second completion joints, the method comprising:

• providing the first and second completion joints, each of the first and second completion joints comprising:
• a base pipe;
• a shunt tube disposed along the base pipe;
• and
• a tubular outer shroud disposed about respective portions of the shunt tube and the base pipe;
• coupling the shunt tube of the first completion joint to the shunt tube of the second completion joint with a jumper tube;
• shifting a tubular sliding shroud from a first position to a second position;
• and
• locking the tubular sliding shroud in the second position;
• wherein the tubular sliding shroud is disposed about at least one of the first and second completion joints in the first position;
• and
• wherein the tubular sliding shroud is disposed about the jumper tube and respective portions of the first and second completion joints in the second position.
