Abstract: A system and method to controlling fluid flow to/from multiple intervals in a lateral wellbore. The system and method can include a unitary multibranch inflow control (MIC) junction assembly (a primary passageway through a primary leg and a lateral passageway through a lateral leg) installed at an intersection of main and lateral wellbores.

Abstract: A downhole apparatus can include a first lateral tubing support that comprises: a body; a first passage extending through the body; and a second passage extending through the body. The first and second passage are spaced in parallel arrangement, and the body extends continuously and uninterruptedly in a direction transverse to the parallel directions of extension of the first and second passages, from the first passage to the second passage. The lateral tubing string can also include a first tubular and a second tubular spaced in parallel arrangement. The first passage is configured to at least partially encircle the first tubular and the second passage is configured to at least partially encircle the second tubular, with the first lateral tubing support increasing a radial and/or axial compressive load rating of the lateral tubing string.

Abstract: Certain shear bolts described herein provide failure bending resistance when torque is applied to members being connected by the bolts, while maintaining shearability. Certain other shear bolts described herein provide a shear region having different shear limits dependent upon the direction of force being applied to the shear region.

Abstract: A lateral wellbore access system is used for moving an isolation sleeve relative to a window of a completion sleeve to adjust access through the window. The system includes an actuator having an isolation sleeve coupling mechanism and a driving mechanism. The isolation sleeve coupling mechanism is configured to engage with an isolation sleeve. The driving mechanism is configured to longitudinally reciprocate the isolation sleeve coupling mechanism within a bore of a completion sleeve to longitudinally move an isolation sleeve coupled to the isolation sleeve coupling mechanism within the bore relative to a window of the completion sleeve. Movement of the isolation sleeve adjusts a position of the isolation sleeve relative to the completion sleeve window for permitting or blocking access through the window into the bore.

Abstract: Systems and methods are described for drilling a new secondary wellbore from a primary wellbore in which a production string is already deployed. The production string is severed below a desired kick-off location for the new secondary wellbore and the upstream portion of the production string is withdrawn from the primary wellbore, thereby exposing an end of the remaining production string. A lateral orientation device (LOD) is mounted on the exposed end of the production string. The LOD includes a shoulder for seating on the exposed end, anchoring mechanism(s) to secure the LOD to adjacent tubular(s), and seals to sealingly engage adjacent tubulars. The LOD may include a contoured surface for orientation of a tool, such as a whipstock, which may be utilized to drill a new wellbore. Alternatively, a work string may be coupled with the LOD to perform pumping operations in the wellbore below the LOD.

Abstract: Various embodiments include methods and apparatus structured to increase efficiencies of a drilling operation. An apparatus can be structured to include a sleeve structured to operatively fit over a liner or a casing in a wellbore. The sleeve can be structured with a packer element disposed such that the liner or the casing is capable of rotation within the sleeve when the sleeve with the packer element is operationally non-rotating. Additional apparatus, systems, and methods can be implemented in a variety of applications.

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.

Abstract: A wellbore isolation system is disclosed. The wellbore isolation system includes a junction positioned at an intersection of a first wellbore and a second wellbore, and a deflector disposed in the junction such that a path into the first leg of the junction is obstructed and engaged with the first leg of the junction to form a fluid and pressure tight seal.

Abstract: Systems and methods for stimulating wells include a frac window system positioned in a first wellbore adjacent a secondary wellbore extending from the first wellbore so that an opening in the frac window system aligns with a window in the first wellbore casing. The frac window system includes an elongated tubular with annular seals along the outer surface above and below the opening in the elongated tubular, and further includes an orientation device carried within the tubular.

A whipstock seats on the orientation device so that a surface of the whipstock is aligned with the secondary wellbore window of the first wellbore casing. The whipstock guides a straddle stimulation tool into the secondary wellbore from the first wellbore.
