The disclosed embodiments include multilateral completion systems and methods to deploy multilateral completion systems. A multilateral completion system includes a main bore completion having an inductive coupler, a lateral completion having an inductive coupler, and a second lateral completion also having an inductive coupler. The multilateral completion system also includes a junction having an inductive coupler, and a second junction having an inductive coupler. The multilateral completion system further includes a final completion having a first inductive coupler electrically connected to the inductive coupler of the main bore completion, a second inductive coupler electrically connected to the inductive coupler of the lateral completion, a third inductive coupler configured to couple to the inductive coupler of the second junction, and an electrical conduit running through an inner diameter of the junction, whereby the main bore completion, the lateral completion and the second lateral completion are all electrically connected in parallel.

Provided, in one aspect, is a deflector assembly. The deflector assembly, in one embodiment, includes a deflector body having a deflector window located therein, and a deflector ramp positioned at least partially across the deflector window, the deflector ramp configured to move between first ({circle around (1)}), second ({circle around (2)}) and third ({circle around (3)}) different positions when a downhole tool moves back and forth within the deflector body.

Methods and apparatus for milling a window for a lateral wellbore in a casing string. An example method introduces a milling assembly into a primary wellbore, the milling assembly comprising: a whipstock, a guide bar coupled to the whipstock, and a wash pipe coupled to the guide bar. The method further includes running the milling assembly to a depth at which it is adjacent to the window in the casing string; securing the whipstock in the casing string; decoupling the wash pipe from the guide bar; guiding the wash pipe to mill the guide bar without milling the whipstock; and milling the window in the casing string with the wash pipe.

A support device may include an upper portion that has a first width and a base portion that has a second width. The support device may be sized to be positioned within a tubing string. The support device may be removable from the tubing string. The support device may include a vertical support that connects the upper portion to the base portion. The vertical support may have a third width and defining a fluid flow path between the vertical support and an inner surface of the tubing string.

Support device for tubing string

A well system including a parent wellbore, a lateral wellbore extending from the parent wellbore, and a reentry window assembly installed within the parent wellbore and including a completion window assembly having a window and providing an upper coupling, a muleshoe, and upper and lower slots provided on opposing axial ends of the window. An isolation sleeve is positioned within the completion window assembly and includes a sleeve alignment key, a sleeve coupling, and an engagement device. A whipstock is matable with the sleeve coupling and an aligning tool is operatively coupled to the whipstock and engageable with the muleshoe to angularly orient a whipstock face to the window. The isolation sleeve is movable between closed and open positions to isolate the lateral wellbore, and the sleeve alignment key interacts with the upper and lower slots to angularly orient the isolation sleeve while moving between the first and second positions.

Multilateral intelligent completion with stackable isolation

A whipstock assembly includes a whipstock providing a ramped surface, and a mill releasably coupled to the whipstock with a shear bolt and providing a mill profile. A tension arm is pivotably coupled to the whipstock and movable between a stowed position, where the tension arm is received within a cavity defined in the ramped surface, and an engaged position, where an engagement head of the tension arm mates with the mill profile to assume at least a portion of a tensile load assumed by the shear bolt.

Whipstock assemblies with a retractable tension arm

An example whipstock assembly includes a whipstock providing a ramped surface and a longitudinal groove defined in the ramped surface. A lead mill is coupled to the whipstock with a shear bolt and providing one or more blades, and a bearing support is arranged within the longitudinal groove and provides opposing sidewalls that define a slot configured to receive one of the one or more blades and thereby prevent the lead mill from rotating with respect to the whipstock.

Mill blade torque support

Assemblies that can be disposed in a subterranean bore are described. Certain assemblies can be used to orient a second pipe with respect to a first pipe in a bore. A second pipe can be rotationally oriented without breaking one or more control lines that may be associated or included with the second pipe by using a tool that orients the second pipe as the second pipe is moved toward a surface of the bore. In some embodiments, assemblies can be used to orient multiple portions of the second pipe with respect to multiple windows of the first pipe. The first pipe may be a casing string and the second pipe may be a tubing string.
