  • Patent number: 8146655
    Abstract: A method (and corresponding apparatus) for downhole fluid analysis of petroleum formation fluids. The method includes capturing in a chamber of a downhole tool at least two immiscible formation fluids in a generally segregated state (the fluids including petroleum), activating a fluid mixing means to mix the fluids in the chamber to create an emulsion therefrom, and allowing the emulsified fluids to segregate while measuring light transmittance through the segregating fluids in order to calculate a transition time period based on the light transmittance through the fluids in the chamber. The transition time period is preferably bounded by the time required for the light transmittance values measured by the light detector to reach a baseline light transmittance. The transition time period characterizes the stability of an emulsion formed by the captured fluids. The methods and apparatus can also be used for other fluid testing applications beyond downhole formation fluid testing.

LM = a + b ? ( ? T ) c , where T is the temperature of the heavy oil sample, ? is the viscosity, T2LM is the logarithmic mean of the T2 distribution spectrum of the sample, and a, b, and c are non-zero constants.

  • 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.

  • Patent number: 7637167
    Abstract: An apparatus (and corresponding method) for characterizing the fluid properties of a two phase fluid includes a restriction element (e.g., orifice plate or nozzle) along the flow path of the two phase fluid. At least one temperature sensor measures temperature of the two phase fluid flowing through the restriction element. A pressure sensor measures the pressure downstream of the restriction element. Time-of-flight measurements of pulses passing through the two phase fluid are made. The speed of sound within the two phase fluid is calculated from the time-of-flight measurements. At least one fluid property (e.g., a vapor phase fraction) of the two phase fluid is calculated from the measured pressure, the measured temperature, and the calculated speed of sound.

  • Patent number: 6184897
    Abstract: A computer implemented representation and a method for encoding and decoding sequences of changes of a manifold triangular mesh. The representation is composed of a base manifold triangular mesh and a succession of specialized mesh surgery operations that may be of a different type. The methods encode or decode any sequence of mark, move, cut, delete, close, fill, or add operations. The mark operation specifies a type of mark and a set of marked elements. The move operation determines a set of displaced vertices from a set of marked elements, and applies a set of vertex displacements to the set of displaced vertices. The cut operation cuts the changing mesh through a set of marked edges. The close operation is applied to one or more boundaries that are determined when the type of mark is a boundary type, and the one or more boundaries are determined by a marked elements variable.
