Abstract: A perforating gun is run in the hole with a valve assembly. Both are remotely actuated with known telemetry techniques. The gun is fired and flow takes place through the gun and is regulated remotely from the surface without further wellbore intervention. The valve assembly can be a sliding sleeve that can be regulated between end positions and in between for flow regulation. Other valve types are contemplated. Signaling can be by acoustic or pressure pulse patterns that work in association with a processor to actuate the gun and the valve assembly in the needed sequence.

Abstract: A perforating gun assembly for a monobore application eliminates a full bore isolation valve or other component that has a limiting internal or external dimension and is designed to remain in position after firing. The assembly is run into the hole on a string with a running tool and left in position with the string and the running tool removed. Pressure pulses communicate with a detonation control system to open a poppet to pressurize a chamber with a firing head. It should be noted that other types firing heads can also be utilized to initiate detonation in the system. Detonation clears the gun internals for flow and opens a gun valve that has no reduction in drift dimension as compared to the gun internal path after detonation. Production takes place through and around the gun. The top of the gun can be entered for future intervention work.

Abstract: Devices and methods for deploying perforating guns through a wellhead production assembly and into a wellbore. In particular embodiments, the invention provides devices and methods for deploying multiple perforating guns through a wellhead production assembly. In the event that the perforating gun assembly is dropped into the wellhead production assembly, a safety clamp will land upon a landing profile within a deployment riser, preventing the perforating gun assembly from falling into the wellbore.

Abstract: A gravel packing system featuring pressure actuated sliding sleeve valves mounted to an exterior annulus around a blanking pipe for screen sections is disclosed. An internal sliding sleeve valve is provided for subsequent closure of access through the screens. The presence of the annulus between the blanking pipe and the screen permits a backup access through perforating the blanking pipe while not damaging the screen. The sliding sleeve valves that are mounted internally and externally on the blanking pipe are removable apart from the screen section that already has gravel packed around it, if they fail to operate and need repair.
