Abstract

A downhole system includes a tubular having a plurality of spaced apertures radially extending through a wall of the tubular. A section of the tubular blocking radial fluid flow through the wall between an interior and exterior of the tubular. The section arranged from a first end to a second end of the tubular. A plurality of filter pucks respectively inserted into at least some of the plurality of apertures. The filter pucks each including a body configured for insertion in one of the apertures and a filtering element within each body; and, at least one control or monitoring line arranged on the section. Further is a method of controlling sand in a downhole system.

First claim

What is claimed:

1. A downhole system comprising:
a tubular having a plurality of spaced apertures radially extending through a wall of the tubular, the apertures arranged in at least one helical array, and a section of the tubular blocking radial fluid flow through the wall between an interior and exterior of the tubular, from a first end to a second end of the tubular, the section extending substantially parallel to a longitudinal axis of the tubular;
a plurality of filter pucks respectively inserted into at least some of the plurality of apertures, the filter pucks each including a body configured for insertion in one of the apertures and a filtering element within each body; and,
at least one control or monitoring line arranged on the exterior of the tubular within the section, the at least one control or monitoring line extending substantially parallel to the longitudinal axis of the tubular;
wherein radial fluid flow through the wall is simultaneously blocked by the section of the tubular and permitted by the filter pucks, and a radial arc length of the section is greater than a combined width of the at least one control or monitoring line.

2. The system of claim 1 wherein the filtering element includes a bonded bead pack configured to block sand from entering an interior of the tubular and to allow fluids to flow through the filtering element.

3. The system of claim 2 wherein the bonded bead pack includes a matrix of bonded stainless steel beads.

4. The system of claim 1 wherein a height of the body and a thickness of the wall of the tubular are substantially the same.

5. The system of claim 1 wherein the filter pucks attached to the tubular protrude from an exterior surface of the tubular.

6. The system of claim 5 wherein the filter pucks protrude further from the exterior surface of the tubular than a diameter of the at least one control line or monitoring line to protect the at least one control line or monitoring line.

7. The system of claim 1 wherein the section is non-apertured and the plurality of apertures are substantially evenly spaced about the tubular except for in the section.

8. The system of claim 1 wherein the body of each filter puck includes a retaining mechanism configured to retain the body within one of the plurality of spaced apertures.

9. The system of claim 1 further comprising a seal interposed between at least one of the plurality of filter pucks and respective aperture.

10. The system of claim 1 further comprising at least one flow-blocking plug insertable within at least one of the plurality of apertures, the at least one flow-blocking plug not including a filtering element and not including a dissolvable member.

11. The system of claim 10 wherein the at least one flow-blocking plug is positioned within an aperture amongst the at least one of the plurality of apertures in the section.

12. The system of claim 1 wherein the filter pucks further comprise a dissolvable membrane to delay a filtering action of the filter pucks.

13. A method of controlling sand in a downhole system, the method comprising:
inserting a plurality of filter pucks into a plurality of radial apertures of a filtering tubular, the apertures arranged in at least one helical array, the filtering tubular having a section blocking radial flow through a wall of the tubular from a first end to a second end of the tubular, the section arranged substantially parallel to a longitudinal axis of the filtering tubular; and,
running at least one control or monitoring line substantially parallel to the longitudinal axis of the filtering tubular in the section;
wherein radial fluid flow through the wall is simultaneously blocked by the section of the tubular and permitted by the filter pucks, and a radial arc length of the section is greater than a combined width of the at least one control or monitoring line.

14. The method of claim 13 , wherein inserting a plurality of filter pucks into a plurality of apertures includes inserting a plurality of filter pucks, each having a body surrounding a filtering element including a matrix of bonded metal beads, into the plurality of apertures.

15. The method of claim 13 , further comprising inserting a plurality of flow-blocking plugs into a plurality of apertures in the filtering tubular to alter the arrangement of flow ports in the filtering tubular, the plurality of flow-blocking plugs not including a filtering element and not including a dissolvable member.

16. The method of claim 13 , further comprising creating the section by inserting a flow-blocking plug into any of the plurality of apertures located within the section designated to accommodate the at least one control or monitoring line, the flow-blocking plug not including a filtering element and not including a dissolvable member.

17. The method of claim 13 , further comprising protecting the at least one control or monitoring line by protruding portions of the plurality of filter pucks attached to the filtering tubular above an exterior surface of the filtering tubular.

18. The method of claim 13 , further comprising threading the plurality of filter pucks into the plurality of apertures such that a first end of the plurality of filter pucks is substantially flush with an exterior surface of the filtering tubular.
