Abstract (en)
[origin: WO2007063324A1] Delivering an additional subterranean conduit (124) along a deflected path relative to an existing conduit (120) is used for installing additional conductor pipes (124) from an existing production platform (50). A deflecting member in the form of a shoe (114, 115; 214) has a coupling means in the form of a screwthread for coupling to a lowermost end of an additional conduit (124). The shoe (114, 115; 214) is arranged to deliver the additional conduit (124) along the deflected path when the shoe (114, 115; 214) contacts whipstock (126; 226) which has been installed on top of an existing conductor pipe (120). The method can include running in the whipstock (126; 226) as a first step on an elongate member such as a drill string (94) and then withdrawing the drill string (94) and then running in the additional conduit (124). The outer diameter of the additional conduit (124) is maximised as it passes through conductor guides (52) attached to the production platform(50).
