Abstract
A method for removal of at least part of a first well tubular metal structure in a borehole of an existing well having a top, the first well tubular metal structure having a longitudinal extension and a first end closest to the top. The method includes inserting a downhole wireline tool having an anchor section and a machining device in the first well tubular metal structure, positioning the downhole wireline tool opposite the first section of the first well tubular metal structure so that the machining device is positioned 8-12 metres from the first end of the first well tubular metal structure and the anchor section is arranged above the machining device, and anchoring the downhole wireline tool opposite the first section by activating the anchor section to abut an inner surface of the first well tubular metal structure.
