A method and device for making lateral openings (36) out of a wellbore (6) in a well formation (8) where fluid is made to flow through a motherbore tubular (2) like a completion or production pipe and then through a needle pipe (4) that is aimed at the formation (8), and where the method includes positioning a needle pipe (4) that comprises at least one pipe section (10, 12) inside or outside a motherbore tubular (2); arranging at least one pipe section (10, 12) to be telescopically displaceable with regard to an other pipe (10, 12) or the motherbore tubular (2). |
