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.

1. A method for placing an expandable tubular in a wellbore, comprising:lowering an expandable tubular assembly into the wellbore in a single trip, the expandable tubular assembly having a running tool assembly, an expander tool, a first portion with a first outer diameter, and a second portion with a second outer diameter, the first outer diameter being greater than the second outer diameter; affixing the first portion to a location in the wellbore; and expanding the second portion, wherein expanding the second portion comprises traversing the expander tool through the second portion by pushing. 2. The method of claim 1, wherein the location in the wellbore is predetermined.3. The method of claim 2, wherein the predetermined location comprises an existing wellbore feature.4. The method of claim 1, further comprising a force application member connected to the expander tool.5. The method of claim 4, wherein expanding the second portion comprises traversing the expander tool through the second portion by applying a force to the force application member.6. A method for placing an expandable tubular in a wellbore, comprising:lowering an expandable tubular assembly into the wellbore in a single trip, the expandable tubular assembly having a running tool assembly, an expander tool with a force application member connected thereto, a first portion with a first outer diameter, and a second portion with a second outer diameter, the first outer diameter being greater than the second outer diameter; affixing the first portion to a location in the wellbore; and expanding the second portion, wherein expanding the second portion comprises traversing the expander tool through the second portion by applying a force to the force application member such that the expander tool is traversed through by pushing. 7. A method for expanding tubulars, comprising:providing an assembly comprising a length of expandable tubing and a length of larger diameter tubing the expandable and larger diameter tubing connected end to end and the expandable tubing having at least one aperture in a wall thereof for the passage of fluid; running the assembly into a bore with an expansion member at least partially disposed within the larger tubular during the running; and expanding the expandable tubing.
