    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: Wellbore liner apparatus has been invented which, in one aspect, includes at least one tubular member for lining at least part of a lateral wellbore extending from a primary wellbore in the earth, at least one coupling bushing connected to the at least one tubular member and disposed in the primary wellbore, the coupling bushing having a bore therethrough from a top to a bottom thereof. In one aspect, the wellbore liner apparatus has two coupling bushings and a first tubular member and a second tubular member, the first tubular member secured to and extending down from the first coupling bushing to the second coupling bushing which is secured thereto, the second tubular member secured to and extending down from the second coupling bushing, with part of the second tubular member lining the lateral wellbore. Such systems are combinable with a wellbore milling system so that communication between the primary wellbore and the interior of the liner may be reestablished.

    摘要: Methods and apparatus for regulating the function of a suspension system are disclosed herein. Suspension characteristics often contribute to the efficiency of a suspended system. Depending on the desired operating parameters of the suspended system, it may be desirable to alter the functional characteristics of the suspension from time to time in order to maintain or increase efficiency. The suspension hereof may be selectively locked into a substantially rigid configuration, and the damping fluid may be phase separated and/or cooled to increase damping rate during use (or offset rate degradation). The suspension hereof may generate power usable to achieve any or all of the foregoing or to be stored for use elsewhere in the suspended system or beyond.
