Abstract
Apparatus and methods are disclosed for anchoring a first conduit (10) to a second conduit (12). The first conduit (10) is typically an expandable conduit whereby a portion of the first conduit is expanded by applying a radial force thereto to provide an anchor and/or seal between the first (10) and second (12) conduits. An inflatable device (14) is provided that can be used to provide a temporary anchor whilst the first (expandable) conduit (10) is radially expanded. An expander device (16) that is capable of applying a radial expansion force to the first conduit (10) is optionally attached to the inflatable device (14).
Claims20
An apparatus for expanding a tubular in a borehole, comprising:
- a first section of the tubular having an enlarged inner and outer diameter with respect to a second section of the tubular;
- a first device constructed and arranged to expand at least a portion of the outer diameter of the first section;
- and
- a second device constructed and arranged to expand at least a portion of the outer diameter of the second section.
A method of expanding a tubular in a borehole, comprising:
- running an apparatus having first and second devices for expanding the tubular into the borehole;
- expanding a perimeter of a first discrete length of a first section of the tubular with the first device;
- and
- expanding a perimeter of a second separate discrete length of a second section of the tubular, wherein the first section of the tubular has an enlarged inner and outer diameter with respect to the second section of the tubular prior to expanding.
An apparatus for expanding a tubular in a borehole, comprising:
- a first section of the tubular having an enlarged inner and outer diameter with respect to a second section of the tubular;
- and
- an expander tool having an initial outer diameter thereof completely disposed in the first section, the expander tool constructed and arranged to expand the outer diameter of the first section adjacent the expander tool and to expand the outer diameter of the second section.
A method of expanding a tubular in a borehole, comprising:
- running an apparatus having first and second devices for expanding the tubular into the borehole, wherein the devices are located within a first section while running the tubular into the borehole;
- expanding at least a portion of the first section of the tubular with the first device;
- and
- expanding at least a portion of a second section of the tubular different from the first section of the tubular with the second device.
A method of expanding a tubular in a borehole, comprising:
- running an apparatus having first and second devices for expanding the tubular into the borehole, wherein the first device is an inflatable device which acts to create a fluid seal between the inflatable device and the tubular;
- expanding a first discrete length of a first section of the tubular with the first device;
- and
- expanding a second separate discrete length of a second section of the tubular.
