Patent number: 10605068Abstract: An electrochemical fluid sensor for a downhole production tool positionable in a wellbore penetrating a subterranean is provided. The wellbore has a downhole fluid therein. The electrochemical fluid sensor includes a sensor housing positionable in the downhole tool, a sensing solution positionable in the housing (the sensing solution including a mediator reactive to target chemicals), a gas permeable membrane to fluidly isolate the downhole fluid from the sensing solution (the gas permeable membrane permitting the passage of gas to the sensing solution), and a plurality of electrodes positioned about the housing a distance from the gas permeable membrane to measure reaction by the sensing solution whereby downhole parameters may be determined.Type: GrantFiled: December 17, 2013Date of Patent: March 31, 2020Assignee: SCHLUMBERGER TECHNOLOGY CORPORATIONInventors: Laurent Pirolli, Gary Martin Oddie, Andrew Meredith, Nathan S. Lawrence, Kay McGuinness, John Collins

Publication number: 20130312970Abstract: An aqueous fluid contains an aqueous solution or dispersion of a polymer to thicken the fluid together with a cross linking agent to enhance the viscosity of the fluid by crosslinking the polymer, wherein the crosslinking agent comprises supporting structures bearing functional groups to react with the polymer molecules and has a mean particle size of 2 nanometer or more. The supporting structures may be nanoparticles and the functional groups may be boronic acid groups. The concentration of boron in a thickened fluid may be low and in some instances there is resistance to applied pressure. The fluid may be a hydraulic fracturing fluid.Type: ApplicationFiled: November 22, 2011Publication date: November 28, 2013Applicant: SCHLUMBERGER TECHNOLOGY CORPORATIONInventors: Valerie Lafitte, Laetitia Corde, Laurent Pirolli, Gary John Tustin, Bruno Drochon

Patent number: 8114817Abstract: A treatment fluid and system are disclosed for cleaning borehole filtercake using the treatment fluid, wherein the filtercake contains reservoir drilling fluid (RDF) solids. The treatment fluid comprises a fluoride source providing a 1.2 to 5 molar fluoride concentration, and another acid or combination of acids to provide a pH between 1.8 and 5. The treatment fluid is balanced for a dissolving power high enough to have significant dissolution of the filtercake, but low enough for even propagation to avoid premature leak-off.Type: GrantFiled: March 10, 2010Date of Patent: February 14, 2012Assignee: Schlumberger Technology CorporationInventors: Laurent Pirolli, Mehmet Parlar

Patent number: 7712536Abstract: A treatment fluid and a method are disclosed for cleaning borehole filtercake using the treatment fluid, wherein the filtercake contains reservoir drilling fluid (RDF) solids. The method includes pumping the treatment fluid downhole in contact with the filtercake to be removed to establish a differential pressure between the treatment fluid and the formation adjacent the filtercake, and evenly propagating treatment of the filtercake during the differential pressure period to delay breakthrough by the treatment fluid for a period from 1 to 12 hours. The treatment fluid comprises a fluoride source providing a 1.2 to 5 molar fluoride concentration, and another acid or combination of acids to provide a pH between 1.8 and 5. The treatment fluid is balanced for a dissolving power high enough to have significant dissolution of the filtercake, but low enough for even propagation to avoid premature leak-off.Type: GrantFiled: November 29, 2007Date of Patent: May 11, 2010Assignee: Schlumberger Technology CorporationInventors: Laurent Pirolli, Mehmet Parlar
