发明名称 Method of using radial thrust elements to re-enter a previously-installed tubular in a lateral
摘要 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.
