Abstract: A well comprising a primary wellbore and a secondary wellbore leading from said primary wellbore wherein a juncture is formed therebetween, said juncture lined with a tubular member extending from said primary wellbore into said secondary wellbore, characterised in that a stabiliser is provided for, in use, stabilising a mill milling an opening in said tubular into said primary wellbore. A method for milling an opening in a tubular in a well of the present invention, the method comprising the step of milling an opening in said tubular member whilst being stabilised or guided by said stabiliser. The invention also provides a tubular member, a mill, a stabiliser and a system for milling an opening in a tubular in a well of the invention.

Abstract: New wellbore milling systems and methods of their use have been developed, the milling system in one aspect including at least one mill, at least one stabilizing member connected to and above the at least one mill, and the at least one stabilizing member for maintaining position of the at least one mill for milling through the liner into the main wellbore. In certain aspects multiple spaced-apart stabilizers are used above a mill which, in one aspect, may include one or more reaming stabilizers. In one aspect the lowermost stabilizer is spaced-apart from a mill so that the stabilizer does not enter a bend portion of a liner to be milled until milling has commenced.
