Abstract: Present embodiments relate to systems and methods for providing cooling to temperature sensitive components of a downhole tool with an intermittent power supply. To provide one example, a downhole tool may include a temperature sensitive component, an enclosure, a cooling unit, and a heat exchanger. The enclosure may be designed to provide thermal insulation to the temperature sensitive component. The cooling unit may intermittently provide active cooling while the downhole tool is being operated. The heat exchanger may facilitate heat transfer from the temperature sensitive component to the cooling unit when the cooling unit is providing the active cooling. The heat exchanger may also disable heat transfer between the temperature sensitive component and the cooling unit when the cooling unit is not providing the active cooling.

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.

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.

Abstract: Embodiments of the disclosure can include systems, methods, and devices for determining saturation pressure of an uncontaminated fluid. A technique facilitates fluid analysis in situ at a downhole location. Downhole saturation pressure measurements and downhole OBM filtrate contamination of a contaminated fluid may be obtained and a relationship may be determined between the saturation pressure measurements and OBM filtrate contamination. The relationship may be extrapolated to zero OBM filtrate contamination to determine the saturation pressure of the uncontaminated fluid. 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 whether a sample has contamination and other selected characteristics of the sample. The data obtained may be processed to provide a formation volume factor of the oil.

Abstract: A system receives data corresponding to light signals in the plurality of cores, the plurality of cores including a first pair of cores spaced apart laterally along a first direction in the optical fiber, and a second pair of cores spaced apart laterally along a second direction in the optical fiber. The system determines a directional measurement of a dynamic parameter based on the data corresponding to light signals in the plurality of cores, wherein directionality of the directional measurement is indicated by a difference between a response of the first pair of cores to a stimulus and a response of the second pair of cores to the stimulus.
