A method and device for re-entering a previously-installed tubular in a lateral borehole

摘要

A method of and device for re-entering a previously-installed tubular 108 in a lateral borehole 104 from a primary borehole 102 including passing a downhole tool 110 from the primary borehole into the lateral borehole, activating one or more radial thrust elements (212 figure 2A) proximate to a nose portion (203 figure 2A) of the downhole tool to apply a radial thrust to the downhole tool 110 and lift the nose portion into alignment with the tubular, and inserting the nose portion of the downhole tool into the tubular 108.
