  • Publication number: 20200355072
    Abstract: A technique facilitates fluid analysis in situ at a downhole location. According to an embodiment, a sample of fluid, e.g. oil, is obtained from a reservoir at the downhole location in a borehole. A downhole sampling system is used to determine contamination of the sample of fluid and to determine other selected characteristics of the sample. The data obtained is then processed to determine a true phase transition property of a native fluid in the sample of fluid. The sample analysis may be performed at selected stations along the borehole during, for example, a well cleanup operation. The immediate analysis of fluid samples downhole facilitates rapid development of an understanding of fluid characteristics in the reservoir, thus enabling an improved oil recovery strategy.

  • Publication number: 20190145242
    Abstract: A technique facilitates fluid analysis in situ at a downhole location. According to an embodiment, a sample of oil is obtained at the downhole location from oil in a reservoir. A downhole sampling system is used to determine contamination of the sample and to determine other selected characteristics of the sample. The data obtained is then processed to provide a formation volume factor of the oil. The testing may be performed at selected stations along the borehole to facilitate rapid development of a realistic model of fluid distribution and property variation in the reservoir, thus enabling an improved oil recovery strategy.

  • Patent number: 10073042
    Abstract: A method and apparatus are provided for performing in-situ fluid analysis. The method involves obtaining a first and second mixture of uncontaminated oil and a contaminant, wherein a percentage of the uncontaminated oil in the first mixture is different from the second mixture. The method may further include establishing a rate of change of a physical property of the first mixture and the second mixture to estimate a mass density of the uncontaminated oil and a mass density of the contaminant. In addition, the method may include obtaining a volume fraction of the uncontaminated oil for the first mixture and second mixture using the mass density of the uncontaminated oil and the mass density of the contaminant. An optical device may be used to determine a composition of the first and second mixtures in order to calculate a composition of the contaminant and a composition of the uncontaminated oil.
