  • Determining formation fluid variation with pressure
    Patent number: 10731460
    Abstract: A downhole tool is operated to pump fluid from a subterranean formation while obtaining fluid property measurements pertaining to the pumped fluid. The downhole tool is in communication with surface equipment located at the wellsite surface. The downhole tool and/or surface equipment is operated to estimate a first linear, exponential, logarithmic, and/or other relationship between compressibility and pressure of the pumped fluid based on the fluid property measurements. The downhole tool and/or surface equipment may also be operated to estimate a second linear, exponential, logarithmic, and/or other relationship between formation volume factor and pressure of the pumped fluid based on the first relationship. The downhole tool and/or surface equipment may also be operated to measure and correct optical density of the pumped fluid based on the first relationship.
    Type: Grant

    Date of Patent: August 4, 2020
    Assignee: SCHLUMBERGER TECHNOLOGY CORPORATION
    Inventors: Youxiang Zuo, Adriaan Gisolf, Kai Hsu, Li Chen, Beatriz Barbosa
  • Method and apparatus for consistent and robust fitting in oil based mud filtrate contamination monitoring from multiple downhole sensors
    Patent number: 10316655
    Abstract: A method for performing contamination monitoring through estimation wherein measured data for optical density, gas to oil ratio, mass density and composition of fluid components are used to obtain plotting data and the plotting data is extrapolated to obtain contamination levels.
