A sacrificial shroud is disposed over a packing element of a downhole packer to provide isolation from incompatible wellbore fluids and to minimize a tendency for swabbing or packer preset due to fluid flow past the packing element during run-in, thereby allowing for faster run-in speeds. The shroud may be depletive or consumable, such as by dissolution into a wellbore fluid or by melting at a predetermined downhole thermodynamic condition. The shroud may take the form of a sleeve or an applied coating.

Assemblies and methods are provided for positioning a sealing tool within a receptacle and pressure testing a seal between the sealing tool and the receptacle. The assembly may be coupled to the sealing tool for latching the sealing tool into the receptacle. The assembly may include a projection that is movable between a coupled position and an uncoupled position. In the coupled position, the projection may couple the assembly to the sealing tool. In the uncoupled position, the projection may be positioned such that the assembly is not coupled to the sealing tool. The projection may move from the coupled position to the uncoupled position in response to determining a seal is established between the sealing tool and the receptacle.

A method includes conveying a washover whipstock coupled to an orienting latch anchor into a parent wellbore lined with casing and securing the orienting latch anchor to the casing. A washover tool couples to and removes the washover whipstock from the parent wellbore, and thereby exposes a releasable orienting coupling of the orienting latch anchor. A workover whipstock coupled to a junction isolation tool is then conveyed into the parent wellbore and the workover whipstock is coupled to the orienting latch anchor at the releasable orienting coupling. The junction isolation tool is separated from the workover whipstock and advanced into the lateral wellbore, following which the junction isolation tool is retracted back into the parent wellbore to be re-attached to the workover whipstock to remove the workover whipstock from the parent wellbore.

In accordance with presently disclosed embodiments, a system and method for rotationally orienting two wellbore tool components on a tool string relative to each other is provided. The system may include an alignment sub that is simple to operate and allows for quick adjustments to the relative orientations of downhole tool components. The disclosed alignment sub may include a first tubular component on one side and a second tubular component on the other side, and these tubular components are coupled together. The disclosed alignment sub utilizes an axially deformable and variable length sleeve attached to the first tubular component and adjacent to a tip of the second tubular component. The sleeve may provide an appropriate standoff distance between the opposing tubular components while enabling the components to be rotated relative to each other up to at least one full rotation about an axis of the alignment sub.

An assembly and method for completion of lateral wellbores is disclosed. The completion assembly includes a junction fitting with main and lateral legs, and a lateral completion string and anchoring device connected to the downhole end of the lateral leg and the uphole end of the junction fitting, respectively. A working string, positioned within the lateral leg, anchoring device, and lateral completion string, includes a setting tool that is removably connected to the anchoring device and a completion tool assembly located within the lateral completion string. The completion assembly is run by the working string into the wellbore. After setting the anchoring device, the working string conveys the completion tool assembly within the lateral completion string for gravel packing, fracturing, frac-packing, acidizing, cementing, perforating, and inflating packers, for example. After wellbore completion, the completion tool assembly is removed through the lateral leg of the junction fitting.
