Patent number: 8517100Abstract: Single-phase microemulsions, comprising a solvent, a surfactant blend and a carrier fluid, are effective spacer fluids for use during cementing operations. The solvent may be selected from the group consisting of monoterpenes, diterpenes, and alkyl or aryl esters of short-chain alcohols. The surfactant blend comprises a water-wetting surfactant or nonionic surfactant, a co-surfactant and an oil-solubilizing surfactant. The carrier fluid is aqueous. The solvent and surfactant blend are combined with the carrier fluid to produce the well-treatment microemulsion.Type: GrantFiled: May 12, 2010Date of Patent: August 27, 2013Assignee: Schlumberger Technology CorporationInventors: Syed A. Ali, Gunnar Debruijn, Laurent Delabroy, Emmanuel Therond, Bruno Drochon, Cecilia Nguyen

Patent number: 8360151Abstract: Compositions and methods that mitigate pressure buildup in the annular space between two tubular bodies in subterranean wells. The composition of the invention comprises an aqueous solution of crosslinkable acrylamide-base polymer, a crosslinker and a gas. Once foamed and placed in the annular space, the composition provides a resilient, flexible, compressible and durable body that is able to compensate for pressure increases in the annular space, thereby protecting the integrity of the tubular bodies.Type: GrantFiled: November 20, 2009Date of Patent: January 29, 2013Assignee: Schlumberger Technology CorporationInventors: Robert Williams, Emmanuel Therond, Laurent Delabroy

Publication number: 20110086941Abstract: The invention concerns a method of improving characteristics of a set cement in an oil- or gas-well. The method according to the invention comprises adding para-aramid synthetic fibers to a cement slurry; and allowing the cement slurry comprising the para-aramid fibers to set. The characteristic to be improved is the resistance to impact, the resistance to high temperature and pressure variations, and/or the drillability of said set cement uses of para-aramid synthetic fibers to enhance specific mechanical properties of cements in an oil- or gas-well.Type: ApplicationFiled: October 9, 2009Publication date: April 14, 2011Inventors: Emmanuel Therond, Cecilia Nguyen

Patent number: 7836953Abstract: A flexible cement stable at high temperatures contains an extender that is a finely ground bituminous coal and/or a finely ground coke prepared from coal and/or liquid hydrocarbons. Preferred cokes are made from bituminous coals and from petroleum, heavy oil, and oil from tar sands, oil shales or oil sands. The coke is present in an amount up to 100 percent by weight of cement and the particle size is preferably from 1 to 1000 microns. The coke is also effective as an extender, and the slurries and set cements have low specific gravity.Type: GrantFiled: April 7, 2008Date of Patent: November 23, 2010Assignee: Schlumberger Technology CorporationInventors: Gunnar Debruijn, Robert Williams, Emmanuel Therond

Patent number: 7838469Abstract: A method is given for reducing fluid loss in downhole operations such as drilling and completion. A composition containing a fusing solid is injected into the fluid loss flow path; the fusing solid fuses at formation temperature when the injection pressure is released and the formation matrix surfaces forming the flow path close on the composition. The fusing solid is gilsonite, or a similar material, or resin coated particles. The composition may optionally contain one or more of fibers, flakes, an activator, and a dispersant.Type: GrantFiled: October 10, 2008Date of Patent: November 23, 2010Assignee: Schlumberger Technology CorporationInventors: Eric Cunningham, Emmanuel Therond, Paulo Rubinstein

Patent number: 7832479Abstract: A flexible cement stable at high temperatures contains an extender that is a finely ground polyetheretherketone. The cement retains its flexibility for long times at high temperatures, for example those used for steam assisted gravity drainage of heavy oil formations, for example from about 480 to about 644° F. (249 to 340° C.). Compressive strength, tensile strength, permeability and porosity are all stable and suitable for high temperature down-hole oilfield use.Type: GrantFiled: May 22, 2008Date of Patent: November 16, 2010Assignee: Schlumberger Technology CorporationInventors: Robert Williams, Emmanuel Therond, Terry Dammel
