Abstract: A device for drilling a hole in a well tubular and for subsequent injection of a fluid or fluid mixture into an annular space or formation surrounding the well tubular. The device comprises a housing and a drill bit assembly arranged inside the housing. In the drill bit assembly, a drill bit with cutting edges and grooves extending along its outside surface, is arranged. The device further comprises rotation means being capable of rotating the drill bit assembly and a fluid supply for supplying a fluid or fluid mixture to the grooves of the rotating drill bit. A seal is surrounding the drill bit and capable of sealing the device against the inner surface of the well tubular.

Abstract: A device and a method for positioning a tool in a well tubular. The device comprising a housing having jacking arm assemblies with extendable jacking arms for fixating the device inside the well tubular. The device further comprising a tool connected to the housing and bellow assemblies comprising inflatable means for positioning the device substantially in the centre of the well tubular. By deflating the inflatable means and simultaneously activating the jacking arms the device is pushed in a direction which is substantially perpendicular to the well tubular.
