Abstract
Kick-off device (1) in aid of drilling a pair of opposite deviated borehole branches in an underground formation from a single borehole comprising an open-ended tube (2) provided at its upper end with connecting means to join the open-ended tube (2) to a string of casing, and a guide element (4) arranged in the open-ended tube (2) near its lower end, which guide element (4) includes two hollow slanted guide ways (6 and 7) arranged on opposite sides of the guide element (4), wherein the wall of the open-ended tube (2) has elongated openings (9 and 10) facing the slanted guide ways (6 and 7).
