Abstract:
1. A system usable with a well, comprising: a base pipe comprising a central passageway, a first radial port and a second radial port; a first screen to at least partially surround a first portion of the base pipe to create a first fluid receiving region between the first screen and the base pipe; a second screen to at least partially surround a second portion of the base pipe to create a second fluid receiving region between the second screen and the base pipe; a first valve to control fluid communication between the first fluid receiving region and the base pipe; a second valve to control fluid communication between the second fluid receiving region and the base pipe; a valve control communication path adapted to communicate a stimulus to the first and second valves to cause the first valve to transition from a closed state to an open state and cause the second valve to transition from a closed state to an open state in response to the stimulus; and a delay element disposed in the communication path to delay communication of the stimulus to the second valve to cause the first and second valves to operate in a time delayed sequence in response to the stimulus being introduced to the valve control communication path, wherein the first screen, the second screen, the valve control communication path and the base pipe are adapted to be run downhole as a unit.
