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, wherein the shroud defines a chamber between the shroud and the wellbore tubular;
at least one inlet port disposed in a first end of the shunt tube entry device;
one or more baffles disposed between the shroud and the wellbore tubular, wherein the inlet port comprises an opening between adjacent baffles, and wherein each of the one or more baffles is disposed at a non-axial and non-normal angle to a longitudinal axis of the wellbore tubular; and
a shunt tube in fluid communication with the chamber and the one or more inlet ports.

2. The entry device of claim 1 , wherein at least a first portion of the shroud is configured to engage the wellbore tubular at a first end of the wellbore tubular, and wherein the one or more inlet ports are disposed on the first portion of the shroud.

3. The entry device of claim 1 , wherein the one or more baffles comprise a first baffle in alignment with a second baffle.

4. The entry device of claim 3 , wherein the one or more baffles direct the fluid flow in a swirling pattern about the wellbore tubular.

5. The entry device of claim 1 , wherein the one or more baffles comprise a first baffle at a first angle and a second baffle at a second angle, different from the first angle.

6. A method of gravel packing comprising:
passing a slurry through one or more inlet ports into a chamber defined by a shroud at least partially disposed about a wellbore tubular via one or more baffles, wherein each of the baffles are disposed between the shroud and the wellbore tubular at a non-axial and non-normal angle to a longitudinal axis of the wellbore tubular;
passing the slurry from the chamber into one or more shunt tubes, wherein the one or more shunt tubes are in fluid communication with the chamber, wherein passing a slurry through one or more inlet ports into at least one flow path defined between one or more baffles comprises directing the slurry into a swirling flow path; and
disposing the slurry about a sand screen assembly.
