Abstract
A particulate screen suitable for use in a wellbore. The particulate screen is expandable and may be at least partially formed of a bistable tubular. Also, a filter media may be combined with the bistable tubular to limit influx of particulates.
Claims42
A system for filtering in a wellbore environment, comprising:
- a sand screen having a tubular component at least a portion of which is formed of bistable cells.
A system for filtering in a wellbore environment, comprising:
- at least one filter media defining a plurality of perforations, the perforations being selected to provide a predetermined flow regime therethrough.
A system for filtering particulate matter in a wellbore environment, comprising:
- an expandable screen component having a plurality of bistable cells;
- and
- a filter disposed along the expandable screen component.
A method of restricting the flow of particulate matter into a tubing used to carry fluid therethrough, comprising:
- forming a particulate screen with a plurality of bistable cells;
- positioning the particulate screen upstream from the tubing;
- and
- expanding the particulate screen.
A system for improving the collapse resistance of an expandable device, comprising:
- an expandable tubular system for use in a wellbore environment, the expandable tubular system having a first layer overlapping a second layer;
- and
- a locking mechanism, wherein upon expansion of the expandable tubular system, the locking mechanism facilitates maintaining the expandable tubular system in the expanded condition.
A system for filtering in a wellbore environment, comprising:
- a generally tubular base component expandable to a increased diameter, the generally tubular base component having at least one bistable cell;
- an expandable shroud disposed at least partially around the generally tubular base component;
- and
- a filter material disposed intermediate the generally tubular base component and the expandable shroud.
A system for restricting the flow of particulate matter into a tubing used to carry fluid therethrough, comprising:
- means for forming a particulate screen with a plurality of bistable cells;
- means for positioning the particulate screen upstream from the tubing;
- and
- means for expanding the particulate screen.
