  • Patent number: 8311955
    Abstract: The present invention is a method to determine models to predict physical or chemical properties of a petroleum fluid when such properties of such fluids cannot be measured by conventional analytical methods. The invention includes the steps of determining one or more models that predict one or more predetermined properties from a set of oils whose optical spectra and properties are known wherein a model corresponds to each predetermined property which is related to the spectrum, estimating the quality of the models, estimating the predictive quality for samples with unknown properties, augmenting the spectrum with shape parameters and/or properties that are predicted by the step above, and determining the quality and predictive quality of the models. The models are then used to predict properties of very small samples.

  • Patent number: 7935226
    Abstract: A method to remove coke from a coker drum is disclosed. The method includes the steps of impinging fluid from a fluid jet on the inside surface of the coker and then determining the vibration signal of the coker drum. The signal is then transformed to determine the amplitude versus frequency by a Fourier Transform of the vibration signal. The amplitude change of the vibration signal as it goes through a maximum, determines when the coke layer has been cut. The fluid jet is lowered into a new layer of coke.

  • Patent number: 6393906
    Abstract: A method for evaluating sedimentary basins for hydrocarbon potential using aqueous fluid inclusions. Aqueous fluid inclusions are identified in a rock sample. The homogenization temperatures of the fluid inclusions are determined, the optical spectra of the water and methane in the fluid inclusions are measured, and the formation pressures are estimated from the relationship of homogenization temperature and optical spectrum to formation pressure. Formation pressure of the fluid inclusions can be combined with history of the fluid inclusion formation to reconstruct the paleo-history of the basin to evaluate hydrocarbon potential.
