1. A completion string assembly, comprising:
- a tubing at least partially defining an internal bore;
an expandable packer coupled to the tubing at a first segment;
an expandable sealing assembly coupled to the tubing at a second segment;
an isolated annulus formed between the expandable packer and the expandable sealing assembly, wherein the isolated annulus is in fluid communication with a formation;
a permeable barrier coupled to the tubing;
a remotely-controllable valve segment of the tubing, wherein the remotely-controllable valve segment comprises;
an outer tubular coupled between the permeable barrier and the expandable packer;
an inner tubular coupled to an inner string at least partially disposed within the permeable barrier, wherein the inner string defines an inner annulus within the completion string assembly, wherein the inner annulus is further defined by the permeable barrier, a lower seal in the expandable sealing assembly, the inner tubular and the outer tubular, and wherein the permeable barrier comprises a screen that provides an open flow channel between the isolated annulus and the inner annulus;
a port between the isolated annulus and the internal bore, wherein the port provides selective fluid communication between the isolated annulus and the internal bore through the permeable barrier by selective fluid communication between the inner annulus and the internal bore; and
a plurality of remotely-controllable valves responsive to at least one downhole trigger condition to provide selective fluid communication between the internal bore and the inner annulus by selectively blocking the port, wherein at least one of the plurality of remotely-controllable valves is responsive to a different one of the at least one downhole trigger condition of a wellbore from at least one other of the plurality of remotely-controllable valves.

Abstract
An example tubing string may at least partially define an internal bore. The tubing string may include an expandable packer and a permeable barrier. The tubing string may further include a remotely-controllable valve responsive to at least one downhole trigger condition, such as a downhole pressure or temperature condition. The remotely-controllable valve may provide selective fluid communication through the permeable barrier between the internal bore and an annulus outside of the permeable barrier. The remotely-controllable valve may function as at least one of a fluid-loss control valve in a completion string assembly or a circulation valve about a completion string assembly.
