Apparatus and method of stabilizing a flow along a wellbore
First Claim
Patent Images
1. A system usable with a well, comprising:
- a valve control network, the valve control network being a closed loop network located entirely downhole in the well; and
valves located in a wellbore of the well and interconnected by the closed loop network, each valve being associated with a different isolated region of the wellbore and being adapted to regulate a flow through the valve based at least in part on a flow condition of the isolated region associated with the valve and a flow condition of each of the other one or more remaining isolated regions, whereineach valve comprises a compensator to regulate a volume of hydraulic fluid in a control chamber of the valve in response to a pressure of the associated isolated region, andthe closed loop network comprises the compensators and a hydraulic control line in communication with the control chamber of each valve.

Abstract
A system that is usable with a well includes a closed loop network that is located entirely downhole in the well. The system also includes valves that are located in a wellbore of the well and are interconnected by the closed loop network. Each valve is associated with a different isolated region of the wellbore and is adapted to regulate a flow through the valve based at least in part on a flow condition of the isolated region associated with the valve and a flow condition of each of the other isolated regions.

7. A method usable with a well, comprising:
-
providing valves in a wellbore of the well, each valve being associated with a different isolated region of the wellbore; connecting the valves together in a closed loop network located entirely downhole in the well; and using the network to regulate a flow through each of the valves based at least in part on a flow condition of the isolated region associated with the valve and a flow condition of each of the other one or more remaining isolated regions, the using comprising; for each valve, regulating a volume of hydraulic fluid in a control chamber of the valve in response to a pressure of the associated isolated region, and providing a hydraulic control line shared in common with the valves to hydraulically connect to the control chamber of each valve. - View Dependent Claims (8, 9, 10, 11)

12. A system usable with the well, comprising:
-
a string located in a wellbore of the well, the string comprising packers to establish isolated intervals along the wellbore and valves located in the isolated intervals; and a valve control network, the valve control network being a closed loop network located entirely downhole in the well, wherein the valves are interconnected by the closed loop network, and each valve being adapted to regulate fluid communication through the valve between the isolated region in which the valve is located and the string based at least in part on a flow condition of the isolated region and a flow condition of each of the other one or more remaining isolated regions, wherein each valve comprises a compensator to regulate a volume of hydraulic fluid in a control chamber of the valve in response to a pressure of the associated isolated region, and the closed loop network comprises the compensators and a hydraulic control line in communication with the control chamber of each valve. - View Dependent Claims (13, 14, 15, 16)
