摘要： A method and system for processing three component seismic data includes determining a covariance data matrix from three component seismic data for each of a plurality of time periods to obtain eigenvectors and eigenvalues. One or more seismic attributes are calculated from the eigenvectors and eigenvalues for each of a plurality of time periods. A stability measure is determined from the calculated seismic attribute for each of the plurality of time periods and stored for display.

摘要： A method and system of detecting and mapping a subsurface hydrocarbon reservoir includes determining ratio data for a plurality of orthogonal spectral components of naturally occurring low frequency background seismic data. The ratio data may be compared, plotted, contoured and displayed as a subsurface hydrocarbon reservoir map or a hydrocarbon potential map. The ratio data may represent a vertical spectral component of the seismic data over a horizontal spectral component of the seismic data. The subsurface hydrocarbon reservoir map may include contouring the ratio data over a geographical area associated with the seismic data.

摘要： A method and system of for determining near surface velocity structure and statics corrections includes acquiring multicomponent seismic data associated with a sensor location, computing spectrograms for all orthogonal components of the multicomponent seismic data using a processing unit, calculating a median H/V spectrum, calculating an initial Rayleigh ellipticity solution associated with the sensor location and inverting the values associated with the median H/V spectrum with a forward-modelled Rayleigh ellipticity solution to determine a velocity depth distribution associated with the sensor location.

摘要： A method and system for processing synchronous array seismic data includes acquiring synchronous passive seismic data from a plurality of sensors to obtain synchronized array measurements. A reverse-time data process is applied to the synchronized array measurements to obtain a plurality of dynamic particle parameters associated with subsurface locations. These dynamic particle parameters are stored in a form for display. Maximum values of the dynamic particle parameters may be interpreted as reservoir locations. The dynamic particle parameters may be particle displacement values, particle velocity values, particle acceleration values or particle pressure values. The sensors may be three-component sensors. Zero-phase frequency filtering of different ranges of interest may be applied. The data may be resampled to facilitate efficient data processing.

摘要： A method and system for processing synchronous array seismic data includes acquiring synchronous seismic data from a plurality of sensors to obtain synchronized array measurements. A reverse-time data propagation process is applied to the synchronized array measurements to obtain dynamic particle parameters associated with subsurface locations. A maximum energy density imaging condition is applied to the dynamic particle parameters to obtain imaging values associated with subsurface locations. Subsurface positions of energy sources are located from the relative maximum of a plurality of the imaging values associated with subsurface locations.

摘要： A method of locating subsurface hydrocarbon reservoirs includes acquiring seismic data, dividing the seismic data into time windows, applying a data transform to the seismic data having a plurality of components to obtain a smoothed frequency spectrum, selecting one or more local maxima and minima, VMaXi, VLi, VRi determining a frequency product as a function of the maxima and minima in a form for display. Lower and higher ratio thresholds may be selected to further discriminate frequency product selection for display. A display or map of frequency products over a survey area may indicate the presence of subsurface fluid reservoirs.
