摘要： A method and apparatus for predictable downhole milling of a casing window having predetermined location, orientation, dimension and contour geometry. An elongate substantially rigid milling shaft has at least one casing window milling element in fixed relation therewith and has a pilot mill in articulated and rotary driven connection with the milling shaft. The milling shaft is in articulated and rotary driven connection with a rotary drive mechanism. The articulated connection of the pilot mill and milling shaft may incorporate an articulation control system to permit the pilot mill to be maintained substantially coaxial with the milling shaft so that its trajectory at a predetermined stage of window milling can be controlled by the milling shaft when positive guiding by a deflecting tool can no longer be ensured. The deflecting tool is adapted to be set within the well casing and defines an inclined pilot mill guide surface for guiding the pilot mill along a predetermined inclined trajectory for milling into the well casing. The deflecting tool incorporates a generally cylindrical bearing for guiding and providing rotational stabilization to the pilot mill during initial window milling to ensure the accuracy of the pilot bore being milled through the well casing and into the surrounding formation. During window milling the pilot mill guides the milling shaft so that the string mills of the milling shaft remove a portion of the pilot mill guide bearing and form a guide face of predetermined contour on the deflecting tool for guiding other tools through the casing window and into the lateral bore. The deflecting tool may be of tubular geometry so as to guide not only the pilot mill but also the string mill and may also receive the rotary drive motor for guiding and stabilizing thereof.

摘要： A method for creating multiple branch wells from a parent well is disclosed. A multiple branching sub is provided for placement at a branching node of a well. Such sub includes a branching chamber and a plurality of branching outlet members. The outlet members during construction of the branching sub, have previously been distorted into oblong shapes so that all of the branching outlet members fit within an imaginary cylinder which is coaxial with and substantially the same radius as the branching chamber. After deployment of the branching sub via a parent casing in the well, a forming tool is lowered to the interior of the sub. The outlet members are extended outwardly by the forming tool and simultaneously formed into substantially round tubes. Next, each outlet member is plugged with cement, after which each branch well is drilled through a respective outlet member. If desired, each branch may be lined with casing and sealed to a branching outlet by means of a casing hanger. A manifold placed in the branching chamber controls the production of each branch well to the parent well.

摘要： A method and apparatus that allows communications of electrical power and signaling from downhole component to another downhole component employs an inductive coupler assembly. In one arrangement, one portion of the inductive coupler assembly is attached to a production tubing section and the other portion of the inductive coupler assembly is attached to a casing or other liner section. The production tubing inductive coupler portion is electrically connected to a cable over which electrical power and signals may be transmitted. Such power and signals are magnetically coupled to the inductive coupler portion in the casing or liner section and communicated to various electrical devices mounted outside the casing or liner section. In other arrangements, inductive coupler assemblies may be used to couple electrical power and signals from the main bore to components in lateral branches of a multilateral well.

摘要： The invention is a system and method used to seal between an open wellbore and a tubing by bringing the wellbore wall inwardly so as to enable sections of earth from the wellbore wall to create the required seal against the tubing. The earth sections that make up the seal can be created by collapsing the relevant parts of the wellbore wall inwardly or by causing the relevant parts of the wellbore wall to swell inwardly.

摘要： The invention is a sealing system, such as a packer, that is used in a wellbore to seal against an exterior surface, such as a casing or open wellbore. The sealing system includes a swellable material that swells from an unexpanded state to an expanded state thereby creating a seal when the swellable material comes into contact with a triggering fluid.
