摘要： Methods and systems that attenuate noise in seismic data. In one aspect, noise attenuation methods iteratively generate a low-speed noise model of low-speed noise recorded in the seismic data. The seismic data is arranged into a sparse seismic-data matrix. Low-speed noise refers to noise that propagates at speeds less the speed of sound in water. The low-speed noise model includes the low-speed noise and includes interpolated low-speed noise that approximates portions of the low-speed noise typically affected by spatial aliasing and streamer surface irregularities. The low-speed noise model may be subtracted from the sparse seismic-data matrix to obtain a noise-attenuated sparse seismic-data matrix.

摘要： A method for seismic data processing can include obtaining seismic data acquired based upon trigger times and not based upon positions of triggered source elements. The seismic data can include near-continuously recorded seismic data in split records. The split records can be spliced together into a single near-continuous record to produce a trace with seismic data from a single acquired line. The seismic data can be processed by performing a spatial shift for each of a number of time samples to correct for motion of a number of seismic receivers.

摘要： The present invention provides extensions to the sampled spatial wavenumber spectrum of a seismic wavefield on the free surface of the earth or at the bottom of a body of water to wavenumbers higher than the Nyquist limit for the physical layout spacing of the seismic sensor units. The seismic sensor units are comprised of linear sensing elements for at least linear vertical particle motion; and rotational sensing elements for rotational motion around at least one, or more, horizontal axes. Stress and wavefield conditions known on the land surface of the earth or on a water bottom allow the rotational sensing element to yield the transverse horizontal gradient of the vertical particle motion wavefield. This horizontal gradient and the linear vertical particle motion data are utilized in techniques of sample reconstruction to yield an improved horizontal spatial sampling of the linear vertical particle motion wavefield. These reconstructed seismic wavefield samples represent spatial wavenumbers beyond the basic spatial Nyquist limit when using only linear sensors for the seismic sensor unit spacing employed. The method has a wide range of application in seismic surveys for oil and gas exploration and production, and for other purposes.

摘要： Method for generating a new family of seismic attributes sensitive to seismic texture that can be used for classification and grouping of seismic data into seismically similar regions. A 2D or 3D data analysis window size is selected (23), and for each of multiple positions (25) of the analysis window in the seismic data volume, the data within the window are transformed to a wavenumber domain spectrum (26). At least one attribute of the seismic data is then defined based on one or more spectral properties, and the attribute is computed (28) for each window, generating a multidimensional spectral attribute data volume (29). The attribute data volume can be used for inferring hydrocarbon potential, preferably after classifying the data volume cells based on the computed attribute, partitioning the cells into regions based on the classification, and prioritizing of the regions within a classification.

摘要： A method of 3D object delineation from 3D seismic data comprising the steps of, providing 3D seismic data; processing the data based on at least one characteristic whereby said characteristic is extracted from the data and compared with at least one reference characteristic and delineated based on the comparison, and defining a geological element based on the delineation. The characteristics may be adjusted. Data can be processed based on one characteristic then processed based on a second characteristic or data is processed based on two characteristics substantially simultaneously. Data may be processed n times producing n delineations from which the geological element is defined. An algorithm is provided for processing the data which may shift an evolving shape description of an object between explicit and implicit representations, where each shift applies a transformation to the object. Multiple sources of data may be utilized simultaneously to drive the delineation process.
