Abstract
A method of re-entering a previously-installed tubular in a lateral borehole from a primary borehole connected to the lateral borehole includes passing a downhole tool from the primary borehole into the lateral borehole, activating one or more radial thrust elements proximate to a nose portion of the downhole tool to apply a radial thrust to the downhole tool and lift the nose portion into alignment with the tubular, and inserting the nose portion of the downhole tool into the tubular.

A method of re-entering a previously-installed tubular in a lateral borehole from a primary borehole connected to the lateral borehole, comprising:
- passing a downhole tool from the primary borehole into the lateral borehole;
- activating one or more radial thrust elements proximate to a nose portion of the downhole tool to apply a radial thrust to the downhole tool and lift the nose portion into alignment with the tubular;
- and
- inserting the nose portion of the downhole tool into the tubular.
A downhole tool for re-entering a previously-installed tubular in a lateral borehole of a multilateral well, comprising:
- a downhole tool body sized for insertion into the previously-installed tubular;
- and
- one or more radial thrust elements proximate to a nose portion of the downhole tool body and operable to apply a radial thrust to the downhole tool body and lift the nose portion into alignment with the tubular.
