摘要： A window cutting system includes a window mill having a body including a connector member, a tip portion, and a plurality of blades arranged between the connector member and the tip portion. Each of the plurality of blades supports a plurality of cutting elements. A lug pocket is formed in at least one of the plurality of blades adjacent the plurality of cutting elements. A whipstock connector detachably coupled to the window mill. The whipstock connector including an outer surface and an inner surface, and at least one lug projecting radially inwardly from the inner surface. The at least one lug is selectively received by the lug pocket to connect the whipstock connector to the window mill.

摘要： An apparatus for determining a location of an inner string in an outer string includes an axis parallel to a longitudinal axis of the inner string, and a tagging assembly disposed at a tagging location in the outer string, the outer string configured to be deployed into a borehole in a subterranean region, the inner string configured to be advanced through the outer string. The tagging assembly includes a stop component configured to obstruct axial movement of the inner string through the outer string at the tagging location, the stop component configured to be displaced in response to an axial force applied to the stop component by the inner string, to permit the inner string to advance axially beyond the tagging assembly.
