Pressure relieving transition joint
First Claim
1. A transition joint seal for coupling a parent wellbore to a branch wellbore extending outwardly from a window in the parent wellbore, comprising:
- a metal pipe having a wall opening along a first side of the metal pipe and a plurality of apertures along a second side of the metal pipe; and
a swell seal coupled to the metal pipe, the swell seal being swellable in the branch wellbore by increasing in a volume of the swell seal to promote sealing between the window and the metal pipe, and the swell seal having a plurality of apertures,wherein at least one of the apertures in the metal pipe align with at least one of the apertures in the swell seal,wherein the at least one of the apertures in the swell seal is sized to avoid closing the aligned at least one of the apertures in the metal pipe when the swell seal swells, andwherein the apertures in the metal pipe comprise a structure configured to substantially block transport of particulate matter from a formation proximate to the window into the parent wellbore while allowing fluid flow from the formation proximate to the window into the parent wellbore, and the structure is further configured to substantially block crossflow of fluid into the formation proximate to the window.

Abstract
A method of completing a wellbore having a branch wellbore extending outwardly from a window in a parent wellbore comprises positioning a tubular string in the window, wherein the positioning comprises deflecting the tubular string from the parent wellbore into the branch wellbore. The method also comprises providing a particulate barrier outside and against the tubular string proximate the window, the particulate barrier substantially excluding transport of particulate matter from the branch wellbore into the parent wellbore outside of the tubular string through the window. The method also comprises the tubular string passing fluid into the tubular string proximate the window from a formation proximate to the window while substantially excluding transport of particulate matter from the formation proximate to the window into the tubular string.

8. A completion tool for a well having a branch wellbore extending outwardly from a window in a parent wellbore, comprising:
-
a metal pipe comprising an upper end configured to be contained in the parent wellbore upwards from the window, a lower end configured to be contained in the branch wellbore, and a plurality of apertures configured to allow fluid flow into the metal pipe from a formation proximate to the window while blocking transport of particulate matter into the metal pipe; and a swellable seal coupled to the metal pipe and comprising a plurality of apertures, the swellable seal configured to block transport of particulate matter from the formation into the parent wellbore, wherein at least one of the plurality of apertures in the swellable seal is aligned with at least one of the plurality of apertures in the metal pipe, and wherein the at least one of the apertures in the swellable seal is sized to avoid closing the aligned at least one of the apertures in the metal pipe when the swellable seal swells. - View Dependent Claims (9, 10, 11, 12, 13)
