  • Patent number: 8915123
    Abstract: Methods and apparatus for determining a viscosity of oil in a mixture are disclosed herein. An example method includes determining water fractions of a mixture flowing into a downhole tool and determining viscosities of the mixture. The mixture includes water and oil. The example method also includes determining a viscosity of the oil based on the water fractions and the viscosities.
    Type: Grant
    Filed: March 30, 2012
    Date of Patent: December 23, 2014
    Assignee: Schlumberger Technology Corporation
    Inventors: Christopher Harrison, Andreas Hausot, Matthew T. Sullivan, Sophie Godefroy

  • Patent number: 8022707
    Abstract: Methods and apparatus for determining a presence of a non-conductive coating on electrodes in fluid resistivity measurement devices are described. An example method of determining a presence of a non-conductive coating on electrodes of a fluid resistivity measurement device involves obtaining a first electrical potential value associated with a substantially uncoated condition of first and second electrodes of a fluid resistivity measurement device. The example method also involves measuring a second electrical potential value at a location between the first and second electrodes, comparing the first and second electrical potential values, and determining the presence of a non-conductive coating on at least one of the first and second electrodes based on the comparison.

  • Patent number: 7574898
    Abstract: A method and apparatus for providing, e.g., identifying or determining, at least one parameter of a fluid moving through a fluid channel using a vibrating wire in contact with the fluid moving through the fluid channel that is clamped under tension. The vibrating wire is actuated by an actuating device capable of displacing the vibrating wire from an initial position. An interpretation element further is utilized to provide a parameter of the fluid moving through the fluid channel based upon data from the vibrating wire following actuation by the actuation element.
