Abstract: Systems and methods for downhole completions. A downhole running tool can have a body having a bore formed therethrough. A latch member can be disposed on a first portion of the body. A reset member can be disposed on a second portion of the body. A conduit can be formed within a sidewall of the body. The conduit can be located between the first and second portions of the body. A pressure relief port can be disposed at a first end of the conduit; and a first flow port can be disposed at a second end of the conduit. The pressure relief port and first flow port can be in communication with an outer diameter of the body.

Abstract: An apparatus string for use in a wellbore has a plurality of activation modules having first and second ends and containing devices to be activated/initiated downhole. An apparatus string also has a plurality of initiator modules where at least initiator is operatively connected to each activation module and is addressable. Each initiator module may have a safety initiator which when the initiator module is addressed initiates the firing of the shaped charges in the gun module to which it is operatively connected. A wireless transmitter is operatively connected in and integral to the apparatus string for use in transmitting signals to address any initiator module in the apparatus string.

Abstract: A technique that is usable with a well includes deploying a plurality of location markers in a passageway of the well and deploying an untethered object in the passageway such that the object travels downhole via the passageway. The technique includes using the untethered object to sense proximity of at least some of the location markers as the object travels downhole, and based on the sensing, selectively expand its size to cause the object to become lodged in the passageway near a predetermined location.

Abstract: A technique that is usable with a well includes providing a string that includes a tubing conveyed perforating (TCP) gun. The technique includes using a downhole component of the string to communicate uphole an indication of at least a depth or an orientation of the gun.

Abstract: A technique facilitates control over multiple well tools. Multiple well tools can be actuated between operational positions. The well tools are coupled to a plurality of multidrop modules with each multidrop module typically being coupled to one or two well tools. Control lines are connected the multidrop modules, and the multidrop modules have the capability of controlling a number of well tools greater than the number of control lines. Each well tool can be actuated individually by providing pressure inputs through one or more of the control lines.

Abstract: An apparatus string for use in a wellbore is disclosed comprising a plurality of activation modules having first and second ends and containing devices to be activated/initiated downhole. An apparatus string according to the present invention also comprises a plurality of initiator modules where at least initiator is operatively connected to each activation module and is addressable. Each initiator module may comprise a safety initiator which when the initiator module is addressed initiates the firing of the shaped charges in the gun module to which it is operatively connected. A wireless transmitter is provided which is operatively connected in and integral to the apparatus string for use in transmitting signals to address any initiator module in the apparatus string. An apparatus string according to the present invention may be especially useful in perforating operations.

Abstract: A technique is provided to control flow in a well. A well completion comprises one or more flow control valve systems coupled by an electric line and a hydraulic line. Each flow control valve system comprises a flow control valve responsive to hydraulic input via the hydraulic line and an electro-mechanical device. The electro-mechanical device is responsive to inputs via the electric line and is used to control hydraulic input to the corresponding flow control valve.

Abstract: A process is disclosed for assembling a gun tube for use in a perforating system. At a first location, which is not the site where perforating operations are to be conducted, the gun tube is completely assembled except for an initiating device. After transporting the gun tube to the site where perforating operations are to be conducted, an initiator is connected and installed via port in the gun tube.

Abstract: The present invention provides for dynamic sealing in a flow control device. In an embodiment, the flow control device comprises a closure sleeve adapted to slide over the tubing hole. The closure sleeve has a front edge having a wave-like surface. One or more seals are mounted downstream of the tubing hole. The one or more seals cooperate in a fluid-tight manner with the closure sleeve. A protective sleeve is mounted in alignment with the closure sleeve and proximate to the one or more seals. The protective sleeve has a top edge adapted for mating engagement with the wave-like surface of the front edge of the closure sleeve. A return mechanism is provided for automatically returning the protective sleeve to a covering position in which the protective sleeve covers the first seal when the first seal is not covered by the closure sleeve.
