Patent number: 7959864Abstract: Methods and related apparatuses and mixtures are described for detecting hydrogen sulfide in a formation fluid downhole. A detection mixture is combined with the formation fluid downhole. The detection mixture includes metal ions for reacting with hydrogen sulfide forming a metal sulfide, and charged nanoparticles sized so as to inhibit significant aggregation of the metal sulfide so as to enable spectroscopic detection of the metal sulfide downhole. The combined mixture and formation fluid is then spectroscopically interrogated so as to detect the presence of the metal sulfide thereby indicating the presence of hydrogen sulfide in the formation fluid. The mixture also includes chelating ligands for sustaining thermal endurance of the mixture under downhole conditions.Type: GrantFiled: October 26, 2007Date of Patent: June 14, 2011Assignee: Schlumberger Technology CorporationInventors: Li Jiang, Oliver C. Mullins, Gale H. Gustavson, Christopher Harrison, Bhavani Raghuraman, Ronald E. G. Van Hal, Jimmy Lawrence, Kosta Ladavac, A. Ballard Andrews, Timothy Gareth John Jones, Rogerio Tadeu Ramos

Publication number: 20100269579Abstract: A gas separation and detection tool for performing in situ analysis of borehole fluid is described. The tool operates by introducing a reagent to a test sample and causing the resulting mixture to flow through a microfluidic channel where optical testing is performed. The optical testing detects a change in a characteristic of the reagent in response to expose to one or more particular substances in the test sample. The test sample may be borehole fluid, a mixture of borehole fluid and scrubbing fluid subsequently mixed with reagent, a mixture of reagent and gas separated from borehole fluid, or a mixture of scrubbing fluid and gas separated from borehole fluid which is subsequently mixed with reagent. A membrane may be employed to separate one or more target gasses from the borehole fluid.Type: ApplicationFiled: April 22, 2009Publication date: October 28, 2010Applicant: SCHLUMBERGER TECHNOLOGY CORPORATIONInventors: JIMMY LAWRENCE, DAN E. ANGELESCU, CHRISTOPHER HARRISON, TSUTOMU YAMATE, MATTHEW T. SULLIVAN, ROBERT J. SCHROEDER, RONALD E.G. VAN HAL, BHAVANI RAGHURAMAN

Publication number: 20100148780Abstract: Embodiments of the present invention provide systems and methods for detection and/or measurement of gaseous components of multiphase mixtures containing one or more hydrocarbons that may be retrieved down a wellbore or may be being transported in a pipeline. More specifically, but not by way of limitation, embodiments of the present invention may provide for separation of the gaseous components from the multiphase mixtures and detection and/or measurement of the separated gaseous components by direct oxidation or reduction.Type: ApplicationFiled: September 21, 2007Publication date: June 17, 2010Applicant: Schlumberger Technology CorporationInventors: Jimmy Lawrence, Nathan Lawrence, Kay Robinson

Publication number: 20100050761Abstract: A gas separation and detection tool for performing in situ analysis of borehole fluid is described. A separation system such as a membrane is employed to separate one or more target gasses from the borehole fluid. The separated gas may be detected by reaction with another material or spectroscopy. When spectroscopy is employed, a test chamber defined by a housing is used to hold the gas undergoing test. Various techniques may be employed to protect the gas separation system from damage due to pressure differential. For example, a separation membrane may be integrated with layers that provide strength and rigidity. The integrated membrane separation may include one or more of a water impermeable layer, gas selective layer, inorganic base layer and metal support layer. The gas selective layer itself can also function as a water impermeable layer. The metal support layer enhances resistance to differential pressure. Alternatively, the chamber may be filled with a liquid or solid material.Type: ApplicationFiled: August 26, 2008Publication date: March 4, 2010Applicant: SchlumbergerTechnology CorporationInventors: Jimmy Lawrence, Timothy G.J.

Patent number: 7520160Abstract: An electrochemical sensor for measuring contents of a fluid or gas at high pressure and/or high temperature, for use, for example, in a wellbore for hydrocarbon applications, is provided. The sensor includes: a bulkhead-like electrode assembly including a cylindrical housing and a cylindrical electrode structure. The cylindrical electrode structure includes a cylindrical conductive pin extending from a high pressure region to a low pressure region and an electrode connected to one end of the pin at the high pressure region and having an electrode surface for exposure to a flow path of the fluid or gas in the high pressure region. At least a part of the surface of the pin is protected from direct contact with the fluid or the gas by an insulating coating impermeable to the fluid or gas. The pin may include an alternating pattern of protruding and receded portions.Type: GrantFiled: October 4, 2007Date of Patent: April 21, 2009Assignee: Schlumberger Technology CorporationInventors: Michael M Toribio, Akira Kamiya, Stephane Vannuffelen, Noriyuki Matsumoto, Jimmy Lawrence

Patent number: 7043814Abstract: An apparatus is provided with position sensors. When the apparatus has moved one tubular into alignment with another tubular a button on a remote control console is pressed to memorize the position. After the next tubular has been gripped by the apparatus a “recall” button is pressed and the apparatus automatically moves the next tubular to the memorized position. This saves vital seconds in joining tubulars and also reduces the likelihood of threads being damaged due to misalignment of the tubulars.Type: GrantFiled: July 1, 2003Date of Patent: May 16, 2006Assignee: Weatherford/Lamb, Inc.Inventors: Jimmy Lawrence Hollingsworth, Bernd Reinholdt
