Abstract
In connection with a method and a tool for preparing a well for the production of hydrocarbons, it is aimed at perforating a casing portion () and working surrounding sediment () in a channel-forming manner. For this purpose the tool comprises a drilling means for drilling transverse holes through the casing wall when the tool (), which is arranged to be raised/lowered and rotated about its longitudinal axis, shared by the casing (), is placed in a fixed position within the well, through which transverse hole () and into surrounding sediment a jetting hose means () is arranged to jet/dig its way in a channel-forming manner. The drilling and jetting hose means also have inactive stand-by positions protectively retracted within the tool housing (), from and into which they may successively be pushed forward into active working positions and again be withdrawn, as a channel () is completed in the sediment ().
