Abstract
An apparatus includes a base pipe and a fluid control material. The base pipe includes openings, and the fluid control material is mounted to the pipe to control fluid communication through the openings of the pipe. The fluid control material has a permeability that may be changed to selectively control the communication of well fluid through the openings.
Claims22
An apparatus comprising:
- a base pipe comprising openings;
- and
- a fluid control material mounted to the pipe to control fluid communication through the openings, the fluid control material having a permeability that may be changed to selectively control the communication of well fluid through the openings.
A method usable with a well, comprising:
- covering openings in a base pipe with a fluid control material to create a fluid control assembly;
- and
- selectively performing an action to change a permeability of the fluid control material to control well fluid flow through the openings.
An apparatus comprising:
- a cartridge comprising a fluid control material adapted to have different permeabilities to control fluid communication through openings of a pipe that is disposed in a well.
A screen assembly usable with a well, comprising:
- a pipe comprising a wall that surrounds a passageway of the pipe and openings in the wall;
- and
- strands located on the exterior of the pipe in the proximity of the openings, each strand comprising a swellable core enclosed by a protective layer so that when the protective layers of strands are removed the cores swell in the presence of well fluid to substantially impede communication through the openings of the pipe.
