Abstract

An embodiment of an apparatus may include a permeable member made by combining a particulate additive to one or more materials, which materials when processed without the particulate additive form a substantially impermeable mass, wherein the permeable member inhibits flow of solid particles above a particular size through the permeable member.

Claims (10)

1. A method of producing fluid from a formation surrounding a well bore, comprising:

providing a fluid flow device that includes a permeable member made by combining a particulate additive to one or more materials, which materials when processed without the particulate additive produce a closed cell mass, wherein the particulate additive occupies walls of the one or more materials to form openings in the walls, the openings in the walls providing permeability for the permeable member wherein the permeable member inhibits flow of solid particles above a particular size through the permeable member; placing the fluid flow device at a selected location in the wellbore; and

allowing the fluid from the formation to flow through the fluid flow device, wherein the permeable member inhibits flow of solid particles above a particular size through the permeable member.

2. The method of claim 1 , wherein the fluid flow device further includes a tubular member having fluid flow passages therein inside the permeable member and a protective member outside the permeable member.

3. The method of claim 1 , wherein the permeable member includes a shape memory mass and placing the fluid flow device at the selected location in the wellbore comprises:

heating the permeable member to attain a first expanded shape;

compressing the permeable member to second contracted shape;

cooling the permeable member to attain the second contracted shape;

placing the fluid flow device into the wellbore while the permeable member is in the second contracted shape; and

allowing the permeable member to heat to expand to plug a portion of the wellbore inside.
