Water Absorbing Materials Used as an In-flow Control Device
First Claim
1. An apparatus for controlling a flow of a fluid into a wellbore tubular in a wellbore, comprising:
- a flow restriction member positioned along the wellbore tubular, the flow restriction member being configured to transition from a first effective density to a second effective density in response to a change in composition of the flowing fluid.

Abstract
A device or system for controlling fluid flow in a well includes a flow restriction member that transitions from a first effective density to a second effective density in response to a change in composition of the flowing fluid. The flow restriction member may increase in effective density as the water cut of the flowing fluid increases and/or disintegrate when exposed to a selected fluid in the flowing fluid. The flow restriction member may be formed of a water-absorbing material and/or a porous material. The pores may be water permeable but not oil permeable. A method for producing fluid from a subterranean formation includes controlling a flow of fluid into a wellbore tubular with a flow restriction member. The method may include reducing a flow of water into the wellbore tubular when a percentage of water in the flowing fluid reaches a predetermined value.
