Abstract

A shunt tube entry device comprises one or more inlet ports, a shroud disposed at least partially about a wellbore tubular, and a shunt tube in fluid communication with the chamber. The shroud defines a chamber between the shroud and the wellbore tubular, and the chamber is in fluid communication with the one or more entry ports.

First claim

What is claimed is:

1. A shunt tube entry device comprising:
a shroud disposed at least partially about a wellbore tubular;
one or more dividers, wherein the one or more dividers define a plurality of chambers between the shroud and the wellbore tubular, wherein each chamber of the plurality of chambers extends axially along the wellbore tubular from one end of the shroud to a second end of the shroud;
a first retaining ring disposed about the wellbore tubular, wherein the first retaining ring retains the shroud in a position about the wellbore tubular;
at least one inlet port disposed in at least a portion of the first retaining ring; and
a shunt tube in fluid communication with at least one of the plurality of chambers and the one or more inlet ports through the at least one chamber.

2. The entry device of claim 1 , further comprising:
a second retaining ring disposed about the wellbore tubular and axially spaced apart from the first retaining ring, wherein the second retaining ring retains the shroud in the position.

3. The entry device of claim 2 , further comprising:
one or more passageways disposed in the second retaining ring, wherein the one or more passageways provide fluid communication between the at least one chamber and the shunt tube.

4. The entry device of claim 3 , wherein the shunt tube is disposed through the one or more passageways such that an end of the shunt tube is disposed within the at least one chamber.

5. The entry device of claim 3 , wherein the shunt tube is coupled to the one or more passageways.

6. A shunt tube entry device comprising:
a plurality of inlet ports;
a shroud at least partially disposed about a wellbore tubular;
one or more dividers, wherein the one or more dividers define a plurality of chambers between the shroud and the wellbore tubular, wherein each chamber of the plurality of chambers extends axially along the wellbore tubular from one end of the shroud to a second end of the shroud and is in fluid communication with one or more of the plurality of inlet ports; and
one or more shunt tubes, wherein each of the one or more shunt tubes is in fluid communication with at least one of the plurality of chambers.

7. The entry device of claim 6 , wherein the plurality of chambers are arranged in parallel.

8. The entry device of claim 7 , wherein the plurality of chambers are out of fluid communication with each other.

9. The entry device of claim 7 , wherein each chamber of the plurality of chambers is in fluid communication with two or more of the plurality of inlet ports.
