Abstract
In aspects the present disclosure provides systems, devices and methods for controlling the flow of water from a subterranean formation into a production well. In one embodiment, the device may include a flow control member formed from a shape-conforming material and a hydrophilic polymer disposed within the shape-conforming member in an amount sufficient to cause the flow control member to restrict flow of water therethrough.

14. A method of producing a fluid from a formation into a wellbore, comprising:
-
providing a flow control device that includes a flow control member formed from a shape-conforming material and a selected amount of a hydrophilic polymer disposed within the shape-conforming member sufficient to cause the flow control member to restrict flow of water therethrough; placing the flow control device with the flow control member in a first compacted shape at a selected location in the wellbore; allowing the flow control member to attain a second expanded shape; and producing the fluid from the formation into the wellbore by flowing the fluid through the flow control device. - View Dependent Claims (15, 16, 17, 18, 19, 20)
