Abstract
Systems and methods for a shrouded tubular device that includes but is not limited to a tubular member, such as a screen joint; a shroud surrounding at least a portion of the tubular, the shroud is at least a two-piece shroud; and a shim in the annulus between the tubular member and the shroud. By way of example only, the shroud may be located directly radially inward from the joint of two of the shroud pieces.
Claims14
A shrouded tubular device comprising:
- a tubular with a longitudinal axis, the tubular comprising a first tubular portion and a second tubular portion, wherein the first tubular portion and the second tubular portion are disposed along different sections of the longitudinal axis;
- a shroud with perforations comprising a first tubular piece circumferentially surrounding the first tubular portion and a second tubular piece circumferentially surrounding the second tubular portion, the first tubular piece comprising an inner tubular piece end and an outer tubular piece end, the second tubular piece comprising an inner tubular piece end and an outer tubular piece end, wherein the inner tubular piece end of the first tubular piece is positioned adjacent the inner tubular piece end of the second tubular piece so that the first tubular piece and second tubular piece are positioned end-to-end at a junction along the longitudinal axis;
- a sand screen between the tubular and the shroud;
- at least one longitudinal bypass tube between the tubular and the shroud extending longitudinally along the first tubular portion and the second tubular portion;
- and
- a shim between the outer diameter of the tubular and the inner diameter of the shroud and disposed adjacent to the junction of the first tubular piece and the second tubular piece, the shim comprising a ring surrounding the tubular and radially disposed outward from the bypass tube, wherein the inner tubular piece ends of the first tubular piece and the second tubular piece of the shroud are disposed adjacent one another and surround at least a portion of the shim.

A means for filtering particulates from a production fluid, the means comprising:
- a tubular with a longitudinal axis, the tubular comprising a first tubular portion and a second tubular portion, wherein the first tubular portion and the second tubular portion are disposed along different sections of the longitudinal axis;
- a shroud with perforations comprising a first tubular piece circumferentially surrounding the first tubular portion and a second tubular piece circumferentially surrounding the second tubular portion, the first tubular piece comprising an inner tubular piece end and an outer tubular piece end, the second tubular piece comprising an inner tubular piece end and an outer tubular piece end, wherein the inner tubular piece end of the first tubular piece is positioned adjacent the inner tubular piece end of the second tubular piece so that the first tubular piece and second tubular piece of the shroud are positioned end-to-end at a junction along the longitudinal axis;
- and
- a means for maintaining an annular space between the shroud and the tubular.
