Abstract: A technique facilitates improved actuation and use of packers which may be disposed along a well string placed in a borehole, e.g. a wellbore. Each packer may be constructed with a tubing, sometimes referred to as a mandrel, and an expandable metal bladder secured around the tubing via connections. The packer may further comprise a sealing element mounted about the expandable metal bladder. The packer also comprises couplings, e.g. a first coupling and a second coupling, connected at opposite ends of the tubing. The couplings each having a hole therethrough to provide a feedthrough running from an exterior to an interior of the tubing at both ends of the tubing.

Abstract: A ballistically actuated plug (2100) for being deployed in a wellbore casing includes a ballistic housing (2106) and an outer seal housing (2102). The ballistic housing includes a first housing portion including a chamber (2208), and a second housing portion having a noncompressible core. The outer seal housing is circumferentially disposed around the noncompressible core (2216). According to an aspect, the initiator (2206) is positioned within the chamber and a detonation extender (2222) is in ballistic communication with the initiator and is circumferentially disposed around the noncompressible core. The detonation extender is configured to, upon detonation, expand the outer seal housing (2102) from an unexpanded form to an expanded form to secure the outer seal housing within the wellbore casing.

Abstract: A wiper plug can be used in wellbore operations. The wiper plug can include a fishing neck located at a rear portion of the plug. The fishing neck can be a male or female fishing neck. A corresponding male or female fishing tool can be used to retrieve the wiper plug from a tubing string. The wiper plug can include a nose that can land on a landing tool or a female fishing neck of another wiper plug. The wiper plug can be introduced into the tubing string before or after a cement composition. The wiper plug can include a rupture disk that allows an operator at a wellhead to observe a pressure change to indicate the location of the wiper plug and fluid within the tubing string.

Abstract: A gravel pack system includes a liner assembly and a deployment assembly. The liner assembly includes a sand control screen. The deployment assembly facilitates rotation of the liner assembly and circulation through the liner assembly while running the liner assembly into a wellbore using a work string. The deployment assembly includes a crossover tool that is operated to facilitate gravel packing without manipulation of the work string. The deployment assembly also includes a setting tool for setting a packer and/or a sand barrier at the top of the liner assembly.

Abstract: An apparatus includes a sensor for sensing pressure, temperature, or another physical parameter at a wellhead assembly or other oilfield component. In one embodiment, an apparatus includes a wellhead body and a branch assembly coupled to the wellhead body such that a bore of the branch assembly is in fluid communication with an interior of the wellhead body through an access passage of the wellhead body. The branch assembly includes a penetration extending outwardly from the bore to an exterior surface of the branch assembly that is radially outward of the bore, and a sensor is installed in the penetration of the branch assembly. Additional systems, devices, and methods are also disclosed.

Abstract: A plug system includes a lower plug, an upper plug, and a sleeve configured to be positioned at least partially within the lower plug, the upper plug, or both. The sleeve defines one or more channels in an outer surface thereof. The sleeve is configured to shift axially from a first position into a second position with respect to the lower plug. In the first position, fluid is prevented from flowing through the one or more channels. In the second position, the fluid is permitted to flow through the lower plug via the one or more channels.
