  • Patent number: 10885146
    Abstract: Data analysis for structural health monitoring relating to a method of modal identification for structures with non-proportional damping based on extended sparse component analysis. Hilbert transform constructs analytical signal of acceleration response. Analytical signal is transformed into time-frequency domain using short-time-Fourier transform. The criterion is taken as the correlation coefficient of adjacent frequency points is close to 1. Points contributed by only one mode are detected from the time-frequency plane. Phases calculated at single-source-points are used to remove local outliers through local outlier factor method. Amplitudes of complex-valued mode shapes are estimated by Hierarchical clustering of amplitudes for time-frequency coefficients at single-source-points. Averaged phases of grouped single-source-points are estimated phases of complex-valued mode shapes. Finally, complex-valued mode shapes are acquired. Modal responses are estimated by sparse reconstruction method.

  • Patent number: 8392122
    Abstract: A method of forecasting naturally-occurring phenomena, such as seismic activity, includes taking localized measurements of the Earth's gravitational force change using MEM inertial motion units. Trends in the measurements are interpreted and related to a phenomenon of interest, a likelihood of occurrence is predicted based on the relationship, and the likelihood is reported to interested parties, preferably automatically to emergency bulletin sources. Measurements can be taken from above the Earth's atmosphere. The trends can be interpreted by determining blind source separation information directed to the region underneath the Earth's mantle crust to determine composition and/or movement.

  • Publication number: 20130046475
    Abstract: A system and method instantly on-site analyze seismic acceleration signals measured from a primary wave of an earthquake and at a detecting site. The system includes an embedded computing host and a signal preprocessing module. Hardware preprocessing is executed on the seismic acceleration signals; and whether the earthquake is a seismic event is able to be determined according to a seism determining logic. Seismic acceleration signals are converted into ground velocities and ground displacements to obtain a peak ground displacement. A seismic fracture time parameter is calculated through the ground velocities and ground displacements and then a seismic magnitude of the earthquake is obtained. According to the peak ground displacement and the seismic magnitude, an epicentral distance is further calculated. Then a peak ground acceleration of the earthquake's shear wave at the detection site is able to be obtained through the seismic magnitude and the epicentral distance.

  • Patent number: 8363510
    Abstract: A computer implemented method for the detection of features such as faults or channels in seismic images. First, edges are detected in a smoothed seismic image (106). To detect a fault line, an image intensity of the edges is projected in multiple spatial directions, for example by performing a Radon transform (118). The directions of maximum intensity are used to define a fault line (124c). To detect channels, smooth curves are identified within the detected edges (810). Sets of parallel smooth curves (812a) are then identified and used to define channels (812).

  • Patent number: 8126651
    Abstract: Method for obtaining rock parameters such as porosity and vshale directly from inversion of seismic data corresponding to a single trace location. This method is distinguished from existing methods that obtain elastic properties from inversion of seismic data, then relate the elastic parameters to rock lithology parameters such as porosity or vshale because it is accomplished in one step, can incorporate anisotropy and does not require multiple trace locations for stability. The data are separated into partial stacks, and a wavelet is specified for each stack. A set of linearized equations are constructed relating seismic reflectivity to changes in elastic parameters, and another set of linearized equations is constructed relating the changes in elastic parameters to the lithologic parameters. The linearized reflectivity equations are combined with the linearized rock physics equations, convolved with the specified wavelets, and equated to the seismic data.

  • Patent number: 8121792
    Abstract: One or more techniques for determining time-varying stress and strain fields within a subsurface region include integrating a seismic model (110) of a reservoir within the subsurface region with a geomechanical model (140) of the subsurface region. An estimate of the time-varying stress and strain fields within the subsurface region during production of the reservoir are determined, wherein the estimate is based on the integration of the seismic model with the geomechanical model. The integration of the seismic model with the geomechanical model can be used to predict the feasibility of passive seismic monitoring for a reservoir within a subsurface region (170).
