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 method of gravel packing comprising:
passing a slurry through one or more inlet ports into a first 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 first chamber into one or more shunt tubes, wherein the one or more shunt tubes are in fluid communication with the first 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;
disposing the slurry about a sand screen assembly;
receiving a second portion of the slurry within a second chamber, wherein the second chamber is defined by one or more dividers disposed between the shroud and the wellbore tubular; and
passing the second portion of the slurry into one or more secondary shunt tubes; and disposing the second portion of slurry about the sand screen assembly.

2. The method of claim 1 , wherein the second chamber comprises a first sub-chamber and a second sub-chamber, wherein the first sub-chamber and the second sub-chamber are defined by one or more dividers disposed between the shroud and the wellbore tubular, and wherein passing the slurry from the chamber into one or more shunt tubes comprises:
receiving the slurry within the first sub-chamber;
passing the slurry from the first sub-chamber through one or more internal ports;
receiving the slurry in the second sub-chamber through the one or more internal ports; and
passing the slurry from the second sub-chamber into the one or more shunt tubes. tubes.
