Abstract: A multilateral junction comprising a y-block, lateral legs, and a transition sub for use in downhole well environments. The y-block includes a main bore and lateral bores with main bore and the lateral bores having threaded interfaces. The transition sub also includes lateral bores with threaded interfaces for receiving the lateral legs that also have threaded interfaces. The threaded interfaces of the lateral bore of the y-block has a less number of threads than the threaded interfaces of the lateral bores of the transition sub. The lateral leg includes another threaded interface that couples with the threaded interface of the lateral bore. Another end of each lateral leg includes an interface, e.g. a threaded interface, which couples with an interface of a transition sub. The main bore has an internal diameter that is greater than the internal diameter of the lateral bore.

Abstract: Provided is a multilateral junction. The multilateral junction, in one aspect, includes a y-block. The multilateral junction additionally includes a mainbore leg coupled to the y-block, the mainbore leg defining a second overlapping space, and a lateral bore leg coupled to the y-block, the lateral bore leg defining a third overlapping space. The multilateral junction, in this aspect, additionally includes an expanded metal joint located in at least a portion of the second overlapping space or the third overlapping space, the expanded metal joint comprising a metal that has expanded in response to hydrolysis.

Abstract: Provided is an interval control valve. The interval control valve, in one aspect, includes a tubular housing, the tubular housing having one or more openings extending there through, and a sliding sleeve positioned within the tubular, the sliding sleeve configured to move between a closed position closing a fluid path between the one or more opening and an interior of the tubular housing, and an open position opening the fluid path between the one or more openings and the interior of the tubular housing. The interval control valve according to this aspect additionally includes a tubular overlapping with the sliding sleeve, the sliding sleeve and the tubular defining an overlapping space, and an expanded metal joint located in at least a portion of the overlapping space, the expanded metal joint comprising a metal that has expanded in response to hydrolysis.

Abstract: A shear bolt can include a body having a shear portion. A port in the body may be used for introducing a fluid into the body. A core disposed in the body may include a chamber at least partially surrounded by the shear portion. A fluid pressure in the chamber and exerted against the shear portion may be increasable in response to the fluid being introduced through the port, such as to increase an amount of stress in the shear portion and prime the shear bolt for shearing. Additionally or alternatively, a support structure positioned in the chamber may be frangible to reduce support to the shear portion in response to the fluid being introduced through the port, for example, to contribute to priming the shear bolt for shearing.
