Abstract
An entry tube system allows fluid to enter a chamber and flow to one or more shunt tubes connected to a downhole end of the entry tube. The fluid can enter the chamber about all or substantially all of the circumference of an inner mandrel disposed within the entry tube, and flow through the chamber to be directed into the shunt tubes.
