Patent number: 8011438Abstract: An apparatus includes a base pipe and a fluid control material. The base pipe includes openings, and the fluid control material is mounted to the pipe to control fluid communication through the openings of the pipe. The fluid control material has a permeability that may be changed to selectively control the communication of well fluid through the openings.Type: GrantFiled: February 15, 2006Date of Patent: September 6, 2011Assignee: Schlumberger Technology CorporationInventors: John E. Edwards, Ronan Le Gloahec, Claude J. Vercaemer, Philippe Hocquet, Pierre-Yves Corre, Nitin Y. Vaidya

Patent number: 7168485Abstract: An expandable device, such as a sand screen, is used in a wellbore. The expandable device comprises an expandable base pipe and a filter layer that facilitates expansion of the device while maintaining filtering capability.Type: GrantFiled: July 31, 2003Date of Patent: January 30, 2007Assignee: Schlumberger Technology CorporationInventors: Craig D Johnson, Matthew R. Hackworth, Kian Rasa, Christopher S. Del Campo, Rod W. Shampine, Claude J. Vercaemer, Gerhard Schoonderbeek

Patent number: 7055606Abstract: A system and method is provided for utilizing both a wellbore completion and a formation treatment system. The formation treatment system comprises a bypass that directs well treatment fluid around the wellbore completion. The bypass protects the wellbore completion from potentially corrosive or erosive well treatment fluids which, in turn, allows the wellbore completion to remain downhole during the introduction of well treatment fluids.Type: GrantFiled: January 20, 2004Date of Patent: June 6, 2006Assignee: Schlumberger Technology CorporationInventors: Peter A. Goode, Claude J. Vercaemer
-
Patent number: 7040402Abstract: A technique that is usable with a subterranean well includes communicating a fluid into a region of the well and monitoring a level of the fluid communicated via a downhole sensor. The communication is controlled in response to the monitoring.Type: GrantFiled: February 26, 2003Date of Patent: May 9, 2006Assignee: Schlumberger Technology Corp.Inventor: Claude J. Vercaemer

Patent number: 6354373Abstract: An expandable tubing (12) for a well bore hole (14) in which selected length portions (24, 26, 28) are weakened by a slot configuration (FIGS. 2, 3, 4) to obtain predetermined expansion characteristics. The slot configurations are tailored or selected for a predetermined bore hole length and may be expanded to different radial diameters to conform generally to the peripheral contour of the bore hole. Tubing portions (29) between the slotted length potions (24, 26, 28) are unweakened.Type: GrantFiled: November 25, 1998Date of Patent: March 12, 2002Assignee: Schlumberger Technology CorporationInventors: Claude J. Vercaemer, Hubertus V. Thomeer, Robert M. Sorem

Patent number: 6267181Abstract: In one embodiment, the invention relates to a method or process, useful in cementing a well, especially a hydrocarbon well, which is characterized by the use of increased external and internal diameter liners, the method being characterized by provision and use of a novel liner and liner-tool assembly. Novel liner apparatus, a liner-tool assembly, and a fluid circulating tool are also disclosed.Type: GrantFiled: March 17, 2000Date of Patent: July 31, 2001Assignee: Schlumberger Technology CorporationInventors: Erik Rhein-Knudsen, Claude J. Vercaemer, Laurent P. Prouvost, Arthur W. Milne, Jean-Louis Pessin

Patent number: 6230805Abstract: A method of hydraulic fracturing is provided in which at least two separate fracturing fluid components are pumped downhole, one of said components being pumped downhole within coiled tubing. The fracturing fluid components responsible for increasing or decreasing the viscosity of the fracturing fluid are provided downhole separately from the polymer which is to be crosslinked, facilitating a delay in the onset of viscosity increase until the fluid has traveled a substantial distance downhole. Downhole pressures may be determined by measuring the pressure in coiled tubing while the fluid within the coiled tubing is in a non-dynamic condition. In some instances, the fluid can be used to plug or seal the formation from producing undesirable fluids, such as water.Type: GrantFiled: January 29, 1999Date of Patent: May 15, 2001Assignee: Schlumberger Technology CorporationInventors: Claude J. Vercaemer, Terry G. Greene, Douglas J. Pferdehirt

Patent number: 6085838Abstract: A method of cementing a well permitting a reduction in the degree of diameter reduction of casing or liners required, and not requiring excessively large initial conductor casing, is described. The method is characterized by provision of an enlarged wellbore and a novel liner structure which is adapted for expansion of a reduced diameter section thereof downhole, providing, before expansion of the section, unimpeded flow of fluid from the enlarged wellbore during cementing and close fit of the expanded section with the casing or preceding liner, after cementing is completed and expansion of the section. A novel well liner structure and novel well liner expansion means are disclosed.Type: GrantFiled: May 27, 1997Date of Patent: July 11, 2000Assignee: Schlumberger Technology CorporationInventors: Claude J. Vercaemer, Brian W. E. Darling

Patent number: 4537918Abstract: The invention relates to cement compositions for cementing wells, which allow pressure gas-channeling to be effectively controlled up to more than about 485.degree. F. The cement composition contains a styrene-butadiene latex and a stabilizer. The film of latex interrupts gas-channeling after an extremely brief path.Type: GrantFiled: March 30, 1983Date of Patent: August 27, 1985Assignee: Etudes et Fabrication Dowell SchlumbergerInventors: Philippe A. Parcevaux, Bernard M. Piot, Claude J. Vercaemer
