Abstract: A casing window assembly and methods for installing the casing window assembly.

Abstract: A system for opening a window (320) in lateral wellbore construction. The system includes a window joint (300) that is operable to be interconnected within a casing string. The window joint (300) has a window (304) formed therein that is defined by at least one score line (306) that creates a preferentially weaken region within the window joint (300) enabling internal removal of the window (304) in a predictable manner without generating wellbore debris. A window removal tool (310) is operable to be run in the casing string. The window removal tool (310) is operably engagable with the window (304) such that actuation of the window removal tool (310) internally removes the window (304) from the window joint (300), thereby opening the window (320).

Abstract: A method for use in producing a stator for a progressing cavity apparatus which includes the use of electroforming to produce the stator tube. A stator tube for a progressing cavity apparatus which is produced using electroforming and a stator for a progressing cavity apparatus which includes a stator tube produced using electroforming.

Abstract: An apparatus for circumferentially orienting a downhole latch assembly in a wellbore. The downhole latch assembly has a plurality of latch keys including a primary latch key. The apparatus includes a casing string positionable in the wellbore. A window joint is interconnected in the casing string. A latch coupling having a latch profile is interconnected in the casing string downhole of the window joint. An orienting subassembly interconnected in the casing string has an orienting profile positioned uphole of the latch profile such that, after operable engagement of the primary latch key with the orienting profile, axial alignment of the latch assembly with the latch coupling causes operable engagement of the latch keys with the latch profile.

Abstract: A system for circumferentially aligning a downhole latch subsystem in a wellbore. The system includes an outer tool assembly including a latch coupling having a latch profile and a slot subassembly having an axially extending slot profile. An inner tool assembly is positionable within the outer tool assembly. The inner tool assembly includes a latch assembly having a plurality of latch keys and an orienting subassembly having a plurality orienting keys. In operation, after axial alignment of the orienting subassembly with the slot subassembly, rotation of the orienting subassembly causes operable engagement of at least one orienting key with the slot profile and, thereafter, axial alignment of the latch assembly with the latch coupling causes operable engagement of the latch keys with the latch profile.

Abstract: A method for completion of a lateral wellbore using a high pressure multibore junction assembly, which comprises a tubular main leg and a tubular lateral leg. The tubular main leg is secured within a main wellbore and the tubular lateral leg is positioned through a lateral wellbore. The tubular main leg and the tubular lateral leg may be stabilized relative to each other as the multibore junction assembly is lowered into the main wellbore.

Abstract: Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for porting digital rights management services. In one aspect, a system includes: a hardware processor; one or more memory devices coupled with the hardware processor and effecting an operating system for the hardware processor; and a digital rights management (DRM) component having a DRM adaptor configured to check whether the hardware processor has a hardware-based encryption element, use the hardware-based encryption element if available, and use a software-based encryption element if the hardware-based encryption element is not available, wherein the software-based encryption element includes code compiled from source code for the hardware processor, the source code prepared for different computer platforms.

Abstract: Assemblies can be disposed in a subterranean bore. An assembly can include a surface that can divert a cutting tool for creating a branch wellbore and that can divert a completion component for completing the branch wellbore without requiring the assembly or part of the assembly from being removed from a parent wellbore prior to the completion component being diverted.

Abstract: A well system for forming a window in a casing string positioned in a wellbore. The system includes first and second steel casing joints (462, 464) interconnectable within the casing string. An aluminum exit joint (460) is positioned between the first and second steel casing joints (462, 464). The aluminum exit joint (460) has a first interconnection with the first steel casing joint (462) and a second interconnection with the second steel casing joint (464). The aluminum exit joint (460) is operable to have the window formed therethrough. A first sleeve (470) is positioned within the first interconnection to provide galvanic isolation between the aluminum exit joint (460) and the first steel casing joint (462). A second sleeve (472) is positioned within the second interconnection to provide galvanic isolation between the aluminum exit joint (460) and the second steel casing joint (464).

Abstract: Assemblies that can be disposed in a subterranean bore and that can facilitate branch wellbore creation are described. An assembly can include threadedly coupled components having inner and outer sealing members in grooves. The sealing member can cooperate with the components to provide a pressure seal. The assembly can also include a venting member for equalizing pressure in a chamber defined by the coupled components. One of the components can be made from aluminum. At least part of that component can be coated with a coating material that is nonconductive.
