Abstract
A tubing coupling method is provided. In one aspect, the method comprises providing a length of expandable tubing and a length of larger diameter non-expanding tubing, connecting an end portion of the expandable tubing to an end portion of the non-expanding tubing, running the tubing into a bore, and expanding the expandable tubing. The expandable tubing may form part of an expandable well or sand screen, or may be an expandable bore liner.

A method of placing a tubular member in a wellbore, comprising:
- lowering the tubular member into the wellbore, the tubular member having a first portion with a first outer diameter and a second portion with a second outer diameter, wherein the first outer diameter is greater than the second outer diameter and the first and second portions are connected together prior to the lowering;
- hanging the first portion to affix the tubular member to a location in the wellbore;
- expanding the second portion with an expander tool after affixing the tubular member;
- and
- releasing the tubular member from a running tool after hanging the first portion and prior to expanding the second portion.

A method of placing a pipe in a wellbore, comprising:
- lowering the pipe into the wellbore, the pipe having a first portion with a first outer diameter and a second portion with a second outer diameter, wherein the first outer diameter is greater than the second outer diameter and the first and second portions are connected together prior to the lowering;
- affixing the first portion to a location in the wellbore;
- and
- expanding the second portion by traversing an expander tool through the second portion, wherein the first portion has an inner diameter at least as large as a largest outer diameter of the expander tool such that the first portion is not expanded.
