Method and apparatus for expanding and separating tubulars in a wellbore

A method of expanding a tubular, comprising:

• providing an expander tool within the tubular, the expander tool comprising at least two expansion members radially extendable from a body having a longitudinal bore therethrough;
• radially extending one of the at least two expansion members into contact with an inside surface of the tubular to expand a first area of the tubular;
• and thereafter
• radially extending the other one of the at least two expansion members into contact with the inside surface of the tubular to expand a second area of the tubular, wherein the first and second areas are axially spaced from one another.

A method of expanding a tubular, comprising:

• running an expansion assembly that is supporting a tubular into a wellbore;
• actuating the expansion assembly to expand a first portion of the tubular while preventing expansion of a second portion of the tubular;
• and
• actuating the expansion assembly to expand the second portion of the tubular, thereby severing the second portion of the tubular from the first portion of the tubular.

A method of expanding a tubular, comprising:

• running a tubular that is supported by an expansion assembly having a first member and a second member into a wellbore;
• actuating the first member to expand a first portion of the tubular while preventing actuation of the second member;
• and
• actuating the second member to expand a second portion of the tubular.

An apparatus for expanding a tubular, comprising:

• a body having a bore disposed through the body;
• a first member that is radially extendable from the body;
• and
• a second member that is radially extendable from the body and is configured to extend from the body after extension of the first member.
