  • Methods and apparatus for analysis of downhole asphaltene gradients and applications thereof
    Patent number: 7996154
    Abstract: A method and system for characterizing asphaltene gradients of a reservoir of interest and analyzing properties of the reservoir of interest based upon such asphaltene gradients. The analysis employs a correlation that relates insoluble asphaltene concentration to spectrophotometry measurement data measured at depth.
    Type: Grant
    Filed: January 12, 2009
    Date of Patent: August 9, 2011
    Assignee: Schlumberger Technology Corporation

  • Methods and apparatus for characterization of petroleum fluid and applications thereof
    Patent number: 7920970
    Abstract: An improved method and system for characterizing the compositional components of a hydrocarbon reservoir of interest and analyzing fluid properties of the reservoir of interest based upon its compositional components.
    Type: Grant

  • Methods and apparatus for analysis of downhole compositional gradients and applications thereof
    Patent number: 7822554
    Abstract: A method and system are provided for characterizing a reservoir of interest by comparing measured downhole fluid analysis measurement data with predicted downhole fluid analysis measurement data for the corresponding depth within the reservoir. The downhole fluid analysis measurement data may comprise the results of compositional analysis, gas-oil ratio measurements, and spectrophotometry measurements. The compositional analyses may be delumped to characterize the compositional components of the downhole fluid and equations of state may be used to predict compositional gradients and fluid properties with depth. The method and system enable the user to characterize a reservoir as to its states of compartmentalization and equilibrium.
