Abstract
Apparatus for expanding first and second portions of a downhole tubular in a single trip comprises a support and first and second expansion devices. The first expansion device is mounted on the support and is operable to expand a first portion of tubular. The second expansion device is mounted to a second portion of tubular and is adapted to be engaged by the support following the expansion of the first portion of tubular, and is then used to expand the second portion of tubular.
Claims26
An apparatus for expanding first and second portions of a downhole tubular in a single trip, the apparatus comprising:
- a support;
- a first expansion device adapted to be mounted on the support and operable to expand a first portion of tubular;
- a second expansion device adapted to be mounted proximate a second portion of tubular and adapted to be selectively engaged by the support following the expansion of the first portion of tubular and operable to expand the second portion of tubular;
- and
- at least one expansion device stop, to limit the translation of at least one of the expansion devices.
A method of expanding first and second portions of a downhole tubular in a single trip, the method comprising:
- translating a first expansion device mounted on a support through a first portion of tubular to expand said first portion of tubular;
- and
- engaging a second expansion device mounted proximate a second portion of tubular with the support and translating the second expansion device through said second portion of tubular to expand said second portion of tubular.
A method of expanding a tubular having a first portion and a second portion, the method comprising:
- engaging a first expansion device with a support and translating the first expansion device mounted to the support through the first portion of tubular to expand the first portion;
- disengaging the support from the first expansion device;
- and
- engaging a second expansion device with the support and translating the second expansion device mounted to the support through the second portion of tubular to expand the second portion.
A method of expanding a tubular having a first portion and a second portion, the method comprising:
- translating a support through the tubular;
- engaging a first expansion device with the support, the first expansion device mounted proximate the first portion of the tubular and translating the first expansion device through the first portion of tubular to expand the first portion;
- disengaging the support from the first expansion device;
- and
- engaging a second expansion device with the support, the second expansion device mounted proximate the second portion of the tubular and translating the second expansion device through the second portion of tubular to expand the second portion.
An apparatus for expanding first and second portions of a downhole tubular in a single trip, the apparatus comprising:
- a support;
- a first expansion device adapted to be mounted on the support and operable to expand a first portion of tubular;
- and
- a second expansion device adapted to be mounted proximate a second portion of tubular and adapted to be selectively engaged by the support following the expansion of the first portion of tubular and operable to expand the second portion of tubular, wherein the expansion devices define expansion diameters, and the expansion diameters of the expansion devices are the same.
An apparatus for expanding first and second portions of a downhole tubular in a single trip, the apparatus comprising:
- a support;
- a first expansion device adapted to be mounted on the support and operable to expand a first portion of tubular, wherein the first expansion device is adapted to be released from the support after expanding the first tubular portion;
- a second expansion device adapted to be mounted proximate a second portion of tubular and adapted to be selectively engaged by the support following the expansion of the first portion of tubular and operable to expand the second portion of tubular.
