    摘要: Blind wavelet extraction and de-convolution is performed on seismic data to enable its practical usage in seismic processing and to provide quality control of data obtained in areas where data from wells are not available. The wavelet extraction and deconvolution are realized in the time domain by iteration, producing a mixed phase wavelet with minimal prior knowledge of the actual nature of the wavelet. As a result of the processing, the de-convolved seismic reflectivity is obtained simultaneously.

    摘要: Methods and devices for seismic data processing deblend seismic data gathered using simultaneous source acquisition by applying two different deblending techniques. The second deblending technique is applied to residual data obtained after applying the first deblending technique. At least one of these first and second deblending techniques uses a signal-to-noise map.

    摘要: A method of processing multi-component seismic data is provided that comprises determining, in the time-offset domain, a first partition rate for a first event from the multi-component seismic data. Information about near-receiver properties of the earth may be obtained from the first partition rate. The method may further comprise determining, in the time-offset domain, at least a second partition rate for the first event from the multi-component seismic data and/or at least a third partition rate for a second event. Further information about near-receiver properties of the earth can be obtained from the second and/or third partition rate.

    摘要: There is described a method of moveout or velocity analysis of seismic signals using the steps of obtaining such signals 5 from a plurality of receivers, identifying receiver functions within the acoustic signals, analyzing said receiver functions for velocity or moveout characteristics, using the result of said analyzing step to determine, properties of multiple layers of earth located below said 10 receivers. The analyses can involve the use of representation of the traveltime differences as approximated power series of slowness or horizontal distances. The method is the first to comprehensively deal with a multi-layered earth or velocity model.

    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, 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.
