Patent number: 6598682Abstract: 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.Type: GrantFiled: March 1, 2001Date of Patent: July 29, 2003Assignee: Schlumberger Technology Corp.Inventors: Ashley B.

Patent number: 6564876Abstract: 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.Type: GrantFiled: February 9, 2001Date of Patent: May 20, 2003Assignee: Schlumberger Technology CorporationInventors: Vladimir Vaynshteyn, James D.

Patent number: 6298924Abstract: 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.Type: GrantFiled: August 18, 2000Date of Patent: October 9, 2001Assignee: Schlumberger Technology CorporationInventors: Vladimir Vaynshteyn, Christian C.

Patent number: 6173772Abstract: A system used in a subterranean well has a command generator (e.g., a manually operated mud pump) that is configured to furnish a first command stimulus (e.g., pressure pulses having a predetermined signature) downhole. A first assembly (e.g., a testing tool) of the system is located downhole and has a first member (e.g., a valve) that is connected to move the first member in response to the first command stimulus. The movement of the first member generates a second command stimulus, and a second assembly of the system, also located downhole, is connected to respond to the second command stimulus.Type: GrantFiled: April 22, 1999Date of Patent: January 16, 2001Assignee: Schlumberger Technology CorporationInventor: Vladimir Vaynshteyn
