    摘要： A method and system of forming a lateral wellbore in a time and trip saving manner using a mill/drill to locate and place a casing window. In one aspect of the invention, a lateral wellbore is drilled with liner which is subsequently left in the lateral wellbore to line the sides thereof. In another aspect, the mill/drill is rotated with a rotary steerable system and in another aspect, the mill/drill is rotated with a downhole motor or a drill stem.

    摘要： The present invention provides an apparatus and methods to reduce ECD and pressure associated therewith while drilling with casing. In one aspect, the invention provides an energy transfer assembly locatable at a predetermined location in a casing string. The assembly includes an impeller portion in the interior of the casing to be acted upon by the downward moving fluid in the casing and a pump portion disposed outwardly of the impeller portion and arranged in fluid communication with the upward moving fluid in the annulus between the casing and the borehole, adding energy thereto and reducing pressure in the annulus therebelow. In another aspect, the energy transfer assembly is retrievable to the surface of the wellbore prior to cementing. In a further aspect, fluid ports between the interior and exterior of the casing are remotely sealable prior to cementing.

    摘要： A stroke indicator has been invented for indicating that a movable inner member of an hydraulically activated wellbore tool or apparatus has moved, particularly that movement of such a member indicating that a stroke of the tool or apparatus has occurred. In one aspect such an indicator is used to indicate that the stroke of a wellbore tubular patch expander system has been completed. A tubular patch has been invented which includes two or more connected tubular patch members. A tubular patch system has been invented for patching operations which, in one aspect, is useful as a "through tubing" tubular patch system and has a body and a series of selectively expandable members which, once having passed through a tubular of a first diameter, are expandable in a tubular of a second diameter larger than the first diameter and then operable to expand a liner patch to seal a leak in the tubular of the second diameter. Such a system may be used in a tubular disposed within a wellbore or in a tubular on the earth surface.
