Provided is a y-block, a multilateral junction, and a method for forming a well system. The y-block, in one aspect, includes a housing having a first end and a second opposing end, and a single first bore extending into the housing from the first end, the single first bore defining a first centerline. The y-block according to this aspect further includes second and third separate bores extending into the housing and branching off from the single first bore, the second bore defining a second centerline and the third bore defining a third centerline, wherein the second and third centerlines are angled relative to one another.

High-pressure multilateral junction with mainbore and lateral access and control

Provided is a sealing/anchoring subassembly, a well system, and method. The sealing/anchoring subassembly, in one aspect, includes a mandrel, as well as a sealing/anchoring element positioned about the mandrel, the sealing/anchoring element configured to move between a radially retracted state and a radially expanded state. The sealing/anchoring subassembly, according to this aspect, also includes a ratch latch body coupled to the sealing/anchoring element, the ratch latch body configured to hold the sealing/anchoring element in the radially expanded state. The ratch latch body, in one aspect, may include a stroke sleeve having a plurality of stroke sleeve teeth disposed thereon, and a base having a plurality of base teeth disposed thereon, the stroke sleeve teeth and the base teeth configured to directly ratchet along one another to hold the sealing/anchoring element in the radially expanded state.

Internal slip design with minimum backlash for packers seal enhancement

Provided is a downhole tool, a y-block, a well system, and a method for forming a well system. The downhole tool, in one aspect, includes a bottom hole assembly (BHA) having an uphole end and a downhole end, and a shroud positioned around and proximate the downhole end of the BHA, the shroud operable to slide relative to the BHA. The downhole tool, in this aspect, may further include one or more shear features coupling the shroud to the downhole end of the BHA.

Downhole tool with a releasable shroud at a downhole tip thereof

Provided is a multilateral leg bore, a multilateral junction, and a well system. The multilateral leg bore, in one aspect, includes a unitary housing having a first end and a second opposing end defining a length (L). In accordance with this aspect, the multilateral junction includes three or more bores formed in the housing and extending along the length (L).

Unitary lateral leg with three or more openings

Provided is a multilateral junction (MLT), a well system, and a method for forming a well system. The MLT, in one aspect, includes a y-block having a housing with a single first bore and second and third bores extending therein, the second and third bores defining second and third centerlines. The MLT, in this aspect, further includes a mainbore leg having a first mainbore leg end coupled to the second bore and a second opposing mainbore leg end, and a lateral bore leg having a first lateral bore leg end coupled to the third bore and a second opposing lateral bore leg end. In this aspect, the mainbore leg and the lateral bore leg are twisted with respect to the second and third bore such that a first plane taken through centerlines of the second opposing mainbore leg end and the second opposing lateral bore leg end is angled.

Multilateral junction with twisted mainbore and lateral bore legs

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.
