摘要： Wellbore operations (e.g. for milling and/or drilling) are disclosed which require a reduced number of tool trips into a wellbore to create a cut-out pocket, opening, or window in a tubular such as casing in the wellbore; and, in some aspects, to continue into a formation adjacent a main wellbore forming a lateral wellbore in communication with the main wellbore. Preferably one trip is required to complete a window or a window and the lateral wellbore. In one aspect a full gauge tool body is used so that the completed lateral wellbore is of a substantially uniform diameter along its entire length, which, in one aspect is suitable for the passage therethrough of full gauge tools, pipe, devices, and apparatuses. In one aspect a cutting system has cutting apparatus initially covered with a wearable away material which is worn away by contacting a tubular to be milled, exposing the cutting apparatus for milling and/or for drilling formation adjacent the wellbore. In certain aspects the lateral wellbore is: about one foot long; two feet long or less; five feet long or less; between five feet and fifty feet long; one hundred feet long or less; between about one hundred and about two hundred feet long; or two hundred or more feet long. In one aspect mill-drill tools are disclosed that both mill tubulars and drill formation.

摘要： A downhole wellbore tool has been developed which has a lower movable valve apparatus which, when it contacts a member in a wellbore or in a tubular in a wellbore, is moved to close off fluid flow through the item to which the valve apparatus is attached. In one aspect, such a valve apparatus is used below a mill above which is positioned a downhole motor which rotates the mill for milling. Actuation of the valve apparatus results in a cessation of the circulation of the motive fluid flowing to and through the motor so that milling stops. In one aspect the valve is selectively operable so that milling may be resumed. In another aspect such a tool is useful for indicating a known location in a wellbore when a decrease or cessation in fluid flow or a decrease in pressure is noticed at the surface.
