  • Publication number: 20190339410
    Abstract: A downhole formation fluid identification sensing module for measuring averaged gas molecular weight of wellbore formation fluid acquires simultaneous temperature, pressure, and density measurements. The sensing module includes two venturi-type gas sensors that both contain vibrating tubes. During operation, formation fluid flows through the vibrating tubes whereby resonant frequency measurements are acquired simultaneously with temperature and pressure measurements. Each measurement is then utilized to determine the gas molecular weight of the dry, wet or saturated formation fluid.

  • Patent number: 10429541
    Abstract: Two or more Integrated Computational Element (“ICE”) structures are designed and utilized in an optical computing device to combinatorily reconstruct spectral patterns of a sample. To design the ICE structures, principal component analysis (“PCA”) loading vectors are derived from training spectra. Thereafter, two or more ICE structures having spectral patterns that match the PCA loading vectors are selected. The selected ICE structures may then be fabricated and integrated into an optical computing device. During operation, the ICE structures are used to reconstruct high resolution spectral data of the samples which is utilized to determine a variety of sample characteristics.

    Abstract: Downhole tools for isolating and analyzing one or more gases include a gas separation assembly in fluid communication with a gas specific analyzer. The gas separation assembly includes a piston disposed within a housing and a separation volume defined between the piston and the housing. The piston is movable to separate a gas component and a liquid component from a downhole formation fluid within the separation volume. The gas specific analyzer is operable to measure one or more properties of the gas component. In some configurations, the gas specific analyzer is an optical assembly containing a light source, an optical detector, and a gas cell that contains an observation volume. The optical assembly is operable to measure one or more properties of the gas component within the observation volume via the light source and the optical detector.

  • Patent number: 10317337
    Abstract: A method for designing an integrated computational element (ICE) includes generating an array of discrete data points and plotting the discrete data points across a predetermined wavelength region. A line shape is then generated that connects to and is constrained by the array of discrete data points, and thereby generates a first transmission function. The discrete data points are then iteratively modified based on one or more performance criteria to generate a second transmission function. A model transmission function corresponding to a model ICE design is then fitted to the second transmission function to identifying a predictive ICE design configured to detect a desired characteristic of interest.

  • Patent number: 10303365
    Abstract: Fingerprints of data portions are distributed in a balanced manner across active controllers of a data storage system, and may be done so in such a manner that, when a new active controller is added to the system, fingerprint ownership and movement between pre-existing active controllers, and active controllers overall, is minimized When a new active controller is added to the system and fingerprints are redistributed, no fingerprint ownership may be re-assigned between pre-existing active controllers and no fingerprints may be moved between pre-existing active controllers, for example, between local memories of the active controller.

  • Publication number: 20190102383
    Abstract: There is provided an association analysis method and apparatus. An original database is divided into projection databases, each not contributing to a support count of a frequent item set of another. The projection databases are used for sequential-pattern association analysis performed respectively by nodes corresponding to the projection databases. Local frequent item sets and corresponding support counts obtained by the nodes are combined. Since an established projection database does not contribute a support count of a frequent item set of another projection database, different nodes can perform association mining, including pruning, on different projection databases respectively.
