Abstract

A tubular for downhole use including a wall defining an inner bore; a fluidic passageway formed within the wall that is fluidically isolated from the inner bore; a portion of the wall being located between the inner bore and the fluid passageway and configured to maintain fluidic isolation between the inner bore and the fluid passageway until an opening is formed through the portion.

First claim

What is claimed is:

1. A tubular for downhole use comprising:
a wall defining an inner bore;
a fluidic passageway formed within the wall that is fluidically isolated from the inner bore;
a portion of the wall being located between the inner bore and the fluid passageway and configured to maintain fluidic isolation between the inner bore and the fluid passageway until an opening is formed through the portion, the wall including at least one feature along the inner bore to axially locate and/or rotationally orient an opening tool relative to the portion;
a first line fluidically connected to the wall at the fluid passageway; and
a second line fluidically connected to the wall at the fluid passageway.

2. The tubular of claim 1 , wherein the inner bore of the tubular serves as a flow bore of a drill string.

3. The downhole tubular system of claim 1 , wherein the first line is positioned on one axial end of the fluid passageway and the second line is positioned on another axial end of the fluid passageway.

4. The downhole tubular system of claim 1 , wherein the first line is positioned on an up-hole end of the fluid passageway and the second line is positioned on a downhole end of the fluid passageway.

5. The downhole tubular system of claim 1 , wherein the lines and the fluid passageway serve as a control line.

6. The downhole tubular system of claim 1 , further comprising a jam nut for sealingly attaching at least one of the first line and the second line to the wall at the fluid passageway.
