    Abstract: Provided is a multilateral junction and a well system. The multilateral junction, in one aspect, includes a housing, the housing including a first housing end and a second housing end, a bore extending through the housing from the first housing end to the second housing end, and a bore coupling profile located along an inside surface of the bore proximate the second housing end. The multilateral junction, according to this aspect, further includes a multilateral bore leg extending into the bore, the multilateral bore leg including a tubular having a first tubular end and a second tubular end, and a tubular coupling profile located along an outside surface of the tubular proximate the first tubular end. The multilateral junction, according to this aspect, further includes an arced coupling located between the bore and the tubular and engaged with the bore coupling profile and the tubular coupling profile.

    Abstract: Some systems and methods include a tubular defining a passageway, one or more packers coupled to the tubular, and two or more valves coupled to the tubular. Some such systems are operable by increasing pressure within the passageway such that, responsive to the increasing pressure, one or more first ones of the valves open and fluid flows from the passageway, through the first valve(s), and into one or more first fractures of the wellbore, and reducing pressure within the passageway such that, responsive to the reducing pressure, the first valve(s) close and one or more second ones of the valves open and hydrocarbons flow from one or more second fractures of the wellbore, through the second valve(s), and into the passageway. The first and second valves can be unidirectional valves.

    Abstract: Wellbore drilling and completion systems implement a method of completing a wellbore. A laser head is mounted to a wellbore drilling assembly positioned within a wellbore formed in a subterranean zone. The laser head emits a first laser beam in a downhole direction within the wellbore to form the wellbore through the subterranean zone. Doing so causes portions of the subterranean zone to be released as drill cuttings into the wellbore. The laser head emits a second laser beam in a radial direction within the wellbore. The second laser beam is incident on a portion of the drill cuttings. The second laser beam causes the portion of the drill cuttings to consolidate and form a casing of the wellbore.

    Abstract: A plurality of energy-generator pods, and methods of use, are provided along a rotatable tubular string extending downhole from surface into a wellbore. In embodiments, rotation of the tubular acts as a rotor of the pod and an outer component about the tubular, capable of relative rotation thereabout, forms the stator. The pod can also be equipped with bi-directional wireless electronic data communication including communication uphole to surface from sensors downhole, pod-to-pod, and down-hole communication to downhole tools. Pods can be fit to centralizers already employed for rotary tubular strings, the centralizer portion engaging the wellbore and remaining stationary relative to the rotating centralized tubular.
