  • Patent number: 9689245
    Abstract: The feasibility of performing hydraulic fracturing can be assessed by analyzing the effect of skin on the overall deliverability of a reservoir. Aspects of the disclosure provide a method to determine equivalent skin in hydraulic fractured system through a semi analytical correlation obtained by numerical modeling. Two 3D models are considered: a base case without fracture and a complex case with fractures. The base case is simulated by varying matrix permeabilities while the fractured model is run with different sets of varying fracture's lengths, widths, and permeability as well as matrix permeabilities. The two cases are comparatively analyzed and skin is determined. A generalized correlation for determination of skin is derived through application of multivariate regression technique on obtained skins and their corresponding variables.

  • Patent number: 9684084
    Abstract: A roadmap for a field development strategy for optimal recovery is provided in a high quality 3D geological model. This geological model combines geological attributes, pore and rock properties for an optimum 3D representation of the reservoir thousands of feet beneath the surface. The model is based on the pertinent geological facies, derived from well core description and detailed studies of rock, as well as fluid and pore properties (Full Pore System) obtained from laboratory analyses of core material and well log data. These data differentiate various important pore throat and pore body regions and relationships, i.e., macroporosity and microporosity. Understanding hydrocarbon volumes in the various pore type groups and then establishing proper recovery techniques through focused laboratory studies yields a field development strategy that can significantly increase hydrocarbon recovery from a reservoir.

  • Patent number: 9678776
    Abstract: Suppressing enabled newer facilities of an older simulated machine. This makes the native machine appear just like the corresponding older simulated machine. The invention creates the Allowed Facilities Table (AFT) that includes all the facilities of each simulated machine that needs to be supported and queries all the installed facilities of the simulated machine. It reads each machine facility of the simulated machine and checks the AFT that includes the state of all the facilities that are allowed to be enabled for the simulated machine to see if this installed facility is also enabled in the AFT. If the installed facility is also enabled in the AFT, then this facility may be used by the software without any problems. Otherwise, this facility should not be used. A system and program product for carrying out the method are included.

  • Patent number: 9679029
    Abstract: Embodiments of the present invention provide an approach for adapting an information extraction middleware for a clustered computing environment (e.g., a cloud environment) by creating and managing a set of statistical models generated from performance statistics of operating devices within the clustered computing environment. This approach takes into account the required accuracy in modeling, including computation cost of modeling, to pick the best modeling solution at a given point in time. When higher accuracy is desired (e.g., nearing workload saturation), the approach adapts to use an appropriate modeling algorithm. Adapting statistical models to the data characteristics ensures optimal accuracy with minimal computation time and resources for modeling. This approach provides intelligent selective refinement of models using accuracy-based and operating probability-based triggers to optimize the clustered computing environment, i.e., maximize accuracy and minimize computation time.

  • Patent number: 9665693
    Abstract: Methods for generating molecular formula distributions beyond a predetermined threshold for a petroleum stream are disclosed. An initial molecular formula distribution within a predetermined threshold is obtained for a petroleum stream. A correlation between two or more molecular properties of the initial molecular formula distribution is identified, and the initial molecular formula distribution is extrapolated beyond the predetermined threshold along the correlation. The extrapolated molecular formula is renormalized based on renormalization data obtained from the sample. The renormalized molecular formula distribution can then be blended with the initial molecular formula distribution, reconciled to secondary analytical measurements, and/or used to create a model of composition and/or a molecular composition-based model of a resid upgrading process. Systems for implementing the methods are also disclosed.

  • Patent number: 9646074
    Abstract: Data clustering is provided according to a dynamical framework based on quantum mechanical time evolution of states corresponding to data points. To expedite computations, we can approximate the time-dependent Hamiltonian formalism by a truncated calculation within a set of Gaussian wave-functions (coherent states) centered around the original points. This allows for analytic evaluation of the time evolution of all such states, opening up the possibility of exploration of relationships among data-points through observation of varying dynamical-distances among points and convergence of points into clusters. This formalism may be further supplemented by preprocessing, such as dimensional reduction through singular value decomposition and/or feature filtering.

  • Patent number: 9607115
    Abstract: Techniques for reporting realistic kinetic energy of a multi-part FEA model are disclosed. FEA model representing a product is received. The product contains more than one parts, each part comprises multiple finite elements. Nodal lumped masses are defined therein to ensure a realistic mass distribution. Kinetic energy of the nodal lumped masses shared by multiple parts is acutely computed for the shared parts. Each of the nodal lumped masses is allocated and accumulated into respective portions as an added mass contribution in accordance with a set of predefined rules for various sharing situations of the finite elements that share the nodal lumped mass. Numerically-simulated structural responses are obtained by conducting a time marching simulation using the FEA model. Finally, kinetic energy of each finite element is reported; calculated using the obtained structural responses, the element mass, and the corresponding added mass contribution from the nodal lumped masses.
