摘要： A packer for use inside a casing of a subterranean well includes a resilient element, a housing and a rupture disc. The resilient element is adapted to seal off an annulus of the well when compressed, and the housing is adapted to compress the resilient element in response to a pressure exerted by fluid of the annulus of a piston head of the housing. The housing includes a port for establishing fluid communication with the annulus. The rupture disc is adapted to prevent the fluid in the annulus from entering the port and contacting the piston head until the pressure exerted by the fluid exceeds a predefined threshold and ruptures the rupture disc.

摘要： A method and apparatus for improving reservoir communication includes, in one arrangement, use of one or more chambers to create an underbalance condition and/or a fluid surge in the wellbore. In another arrangement, a tool string comprises a packer, a circulating valve, and an atmospheric chamber, in which the circulating valve, when open, is adapted to vent a lower wellbore region below the packer when the packer is set, and the atmospheric chamber is capable of being operated to create an underbalance condition below the packer. In yet another arrangement, an apparatus comprises a subsea wellhead equipment including a blow-out preventer, choke line filled with a low density fluid, and a kill line filled with a heavy fluid. The choke line is adapted to be opened to create an underbalance condition in the wellbore. In yet another arrangement, a method of creating an underbalance condition comprises controlling wellbore pressure at least in a perforating interval to achieve a target level, configuring a perforating gun to achieve a target detonation pressure in the perforating gun upon detonation, and creating an underbalance condition in the perforating interval of the wellbore when the perforating gun is shot. In yet another arrangement, a tool string for use in a wellbore extending from a well surface comprises a closure member adapted to be positioned below the well surface, and a chamber defined at least in part by the closure member. The tool string further comprises at least a port selectively openable to enable communication between the chamber and a wellbore region. The port when open creates a fluid surging to the chamber to provide a low pressure condition in the wellbore region. A tool in the tool string is adapted to perform an operation in the low pressure condition.

摘要： An apparatus for use in a subterranean well includes a downhole energy source, a first switch, a second switch, a detonator, a first controller and a second controller. The first switch has a first predetermined state to transfer energy from the energy source, and the second switch has a second predetermined state to transfer the energy from the energy source. A detonator receives the energy from the energy source when the first switch and second switches are concurrently in the first and second predetermined states. A first controller independently detects a predetermined stimulus that is transmitted from the surface of the well and causes the first switch to enter to first predetermined state based on the detection by the first controller. A second controller independently detects the predetermined stimulus transmitted from the surface of the well and causes the second switch to enter the second predetermined state based on the detection by the second controller.

Firing of the perforating gun assembly is initiated via a signal transmitted from the surface above the wellbore. An electrical signal from the wellbore is transmitted to the surface to confirming the firing of perforating gun assembly. The system includes various tools for perforating the well using the disclosed methods.
