Patent number: 9546959Abstract: A method and system that characterizes hydrogen sulfide in petroleum fluid employs a tool that includes a fluid analyzer for performing fluid analysis (including optical density (OD) for measuring carbon dioxide concentration) of a live oil sample, and a storage chamber for an analytical reagent fluidly coupled to a measurement chamber. An emulsion from fluid of the sample and the reagent is produced into the measurement chamber. The reagent changes color due to pH changes arising from chemical reactions between components of the sample and the reagent in the measurement chamber. The tool includes an optical sensor system that measures OD of a water phase of the emulsion at one or more determined wavelengths. The pH of the water phase is derived from such OD measurements. The pH of the water phase and the carbon dioxide concentration in the sample is used to calculate hydrogen sulfide concentration in the sample.Type: GrantFiled: September 16, 2011Date of Patent: January 17, 2017Assignee: SCHLUMBERGER TECHNOLOGY CORPORATIONInventors: Kentaro Indo, Michael M. Toribio, Shu Pan

Patent number: 9074465Abstract: Methods and related systems are described for real-time wellsite production allocation analysis. Spectroscopic in-situ measurements are made in the vicinity of a wellsite of a produced fluid from one or more boreholes. The produced fluid includes in a co-mingled state, at least a first fluid component from a first production zone and a second fluid component from a second production zone. An allocation is estimated in real-time for at least the first fluid component in the produced fluid based at least in part on the spectroscopic in-situ measurements. The in-situ measurements can be several types, for example: (1) absorption of electromagnetic radiation having wavelengths in the range of ultraviolet, visible and/or infrared light, (2) X-ray fluorescence spectroscopy measurements, (3) electromagnetic scattering spectroscopic measurements such as Raman spectroscopy measurements, (4) NMR spectroscopy measurements, and (5) terahertz time-domain spectroscopy measurements.Type: GrantFiled: December 18, 2009Date of Patent: July 7, 2015Assignee: Schlumberger Technology CorporationInventors: Patrice Abivin, Michael M Toribio, Kentaro Indo

Patent number: 8904859Abstract: A gas separation and detection tool for performing in situ analysis of borehole fluid is described. The tool comprises a sampling chamber for a downhole fluid. The sample chamber comprises a detector cell with an opening. The tool also comprises a gas separation module for taking a gas from the downhole fluid. The gas separation module comprises a membrane located in the opening, a support for holding the membrane, and a sealant applied between the housing and the membrane or support. Moreover, the tool comprises a gas detector for sensing the gas.Type: GrantFiled: January 19, 2012Date of Patent: December 9, 2014Assignee: Schlumberger Technology CorporationInventors: Jimmy Lawrence, Tim G. J. Jones, Kentaro Indo, Tsutomu Yamate, Noriyuki Matsumoto, Michael M. Toribio, Hidetoshi Yoshiuchi, Andrew Meredith, Nathan S. Lawrence, Li Jiang, Go Fujisawa, Oliver C. Mullins

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
