Tubing conveyed multiple zone integrated intelligent well completion
First Claim
1. A tubing string for use in a subterranean well, the tubing string comprising:
- at least one well screen;
at least one first flow control device which selectively prevents and permits substantially unrestricted flow through the well screen;
at least one second flow control device, the second flow control device being remotely operable, and wherein the second flow control device variably restricts flow through the same well screen;
wherein the first flow control device and at least a portion of the second flow control device are positioned within the well screen; and
at least one third flow control device, the third flow control device being remotely operable, and wherein the third flow control device variably restricts flow through the same well screen.

Abstract
A system for use with a well having multiple zones can include multiple well screens which filter fluid flowing between a tubing string and respective ones of the zones, at least one optical waveguide which senses at least one property of the fluid as it flows between the tubing string and at least one of the zones, multiple flow control devices which variably restrict flow of the fluid through respective ones of the well screens, and multiple pressure sensors which sense pressure of the fluid which flows through respective ones of the well screens. A tubing string for use in a subterranean well can include at least one well screen, at least one flow control device which selectively prevents and permits substantially unrestricted flow through the well screen, and at least one other flow control device which is remotely operable, and which variably restricts flow through the well screen.

12. A system for use with a subterranean well having multiple earth formation zones, the system comprising:
-
multiple well screens which filter fluid flowing between a tubing string in the well and respective ones of the multiple zones; at least one optical waveguide which senses at least one property of the fluid as it flows between the tubing string and at least one of the zones; multiple flow control devices which variably restrict flow of the fluid through respective ones of the multiple well screens, the multiple flow control devices for each one of the multiple well screens comprising; a first flow control device which selectively prevents and permits substantially unrestricted flow through the well screen; a second flow control device, the second flow control device being remotely operable, and wherein the second flow control device variably restricts flow through the same well screen; wherein the first flow control device and at least a portion of the second flow control device are positioned within the same well screen; a third flow control device, the third flow control device being remotely operable, and wherein the third flow control device variably restricts flow through the same well screen; and multiple pressure sensors which sense a pressure differential across respective ones of the multiple flow control devices. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25)
