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.

The invention claimed is: 1. 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 gr
The invention claimed is: 1. 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. 2. The method of claim 1, wherein the lowering, hanging and expanding all occur in a single trip. 3. The method of claim 1, wherein the expander tool is at least partially disposed in the first portion during lowering of the tubular member. 4. The method of claim 1, wherein releasing the tubular member includes retracting keys of the running tool. 5. The method of claim 4, wherein retracting the keys includes applying fluid pressure to the running tool. 6. The method of claim 1, 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. 7. The method of claim 1, wherein the expander tool is a cone. 8. The method of claim 1, wherein the second portion of the tubular member has a permanent fluid path between an interior and an exterior of the second portion. 9. 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. 10. The method of claim 9, wherein affixing the first portion includes actuating a hanger. 11. The method of claim 9, wherein affixing the first portion includes actuating a packer. 12. The method of claim 9, wherein affixing the first portion includes engaging cooperating threads of an existing pipe in the wellbore. 13. The method of claim 9, further comprising releasing the pipe from a running tool after affixing the first portion and prior to expanding the second portion. 14. The method of claim 13, wherein releasing the pipe includes retracting keys of the running tool. 15. The method of claim 14, wherein retracting the keys includes applying fluid pressure to the running tool. 16. 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 and a second portion, wherein the first and second portions are together prior to the lowering and each have different inner diameters; hanging the tubular member 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 tubular member and prior to expanding the second portion. 17. The method of claim 16, wherein releasing the tubular member includes retracting keys of the running tool. 18. The method of claim 17, wherein retracting the keys includes applying fluid pressure to the running tool. 19. The method of claim 16, 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. 20. The method of claim 16, wherein expanding the second portion comprises traversing the expander tool through the second portion by pushing.
