摘要： Milling operations are disclosed which require a reduced number of tool trips into a wellbore to create a cut-out pocket or window in a tubular such as casing in the wellbore. Preferably one or two trips are required. A milling system is disclosed which is useful in such operations which includes a whipstock with an orientation member secured thereto and a milling apparatus with one or more mills and an extending joint, if needed, with a central channel therethrough for receiving the orientation member as the milling apparatus moves down in the wellbore. Such a system may be used in a single-trip milling operation. The milling apparatus is useful in a two-trip operation in which no orientation member is attached to the whipstock and in which a starting mill is initially run in on a first trip to create an initial pocket in the casing. In one aspect the mill(s) mill off high center producing a piece of casing which enters into the hollow portion of the mill(s) and, as needed, into a hollow portion of an interconnected extension member such as a pup joint.

摘要： A method is provided that allows the operator to re-enter a primary wellbore from a lateral wellbore after the lateral wellbore has been completed. The method generally comprises the steps of locating a cutting device such as a milling bit adjacent a tubular such as a liner within a wellbore, rotating the milling bit while maintaining an axial position of the milling bit relative to the liner to initiate an opening, and rotating and axially advancing the milling bit to complete the opening. In addition, a bottom hole assembly that facilitates re-entry into the primary wellbore from a lateral wellbore is provided. The bottom hole assembly generally includes a drill collar or other heavy pipe structure, and a mill. The mill has a body and cutting structures. The cutting structures apply lateral force against a surrounding pipe to form an initial lip through the wall of the pipe.
