Pressure relieving transition joint
First Claim
1. A transition joint for coupling a parent wellbore to a branch wellbore extending outwardly from a window in the parent wellbore, comprising:
- a tubular string comprising an upper portion configured to be contained in the parent wellbore upwards from the window, a lower portion configured to be contained in the branch wellbore, and a plurality of apertures configured to allow fluid flow into the tubular string from a formation proximate to the window, wherein the plurality of apertures are arranged on the tubular string along a half of the tubular string configured to face a pressure gradient between the formation and the branch wellbore; and
a plurality of pressure relief valves coupled to the apertures in the tubular string, wherein each of the pressure relief valves is configured to be autonomously actuating, and wherein the plurality of pressure relief valves are configured to reduce propagation of particulate matter into the parent wellbore and the branch wellbore when the plurality of pressure relief valves are open.

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.

17. A method of completing a wellbore having a branch wellbore extending outwardly from a window in a parent wellbore, the method comprising:
-
positioning a transition joint in the window, wherein the positioning comprises deflecting the transition joint from the parent wellbore into the branch wellbore, wherein the transition joint comprises a tubular string and a plurality of apertures configured to allow fluid flow into the tubular string from a formation proximate to the window, wherein the plurality of apertures are arranged on the tubular string only along a half of the tubular string configured to face a pressure gradient between the formation and the branch wellbore, and where in the transition joint further comprises a plurality of pressure relief valves coupled to the apertures in the tubular string, wherein each of the pressure relief valves is configured to be autonomously actuating; and the transition joint 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. - View Dependent Claims (18, 19, 20)
