摘要： This invention provides a method for examining the geometry of the disposition of a plurality of sources (18-24) and receivers (10-16) over an area to be surveyed with a view to optimizing the array to avoid data shadow zones and to optimize the resulting seismic image. The method depends upon studying the statistical distribution of dip polarity in dip bins along selected CMP azimuths.

摘要： The objective of this invention is to provide a method for estimating, in the frequency domain, deconvolution operators for removing spurious resonant coupling responses from the cross-line and the vertical seismic signal components in OBC surveys. The purpose is to balance the spectral response of the respective signal component in amplitude and phase in a manner consistent with the field geometry.

摘要： The two-way water-layer travel time, τ, is derived from dual-mode seismic sensor data by cross-correlating the Fourier transforms of the sum and difference of the velocity and pressure signatures. The Z-transform of τ evaluates one of the two Backus variables, Z w . The second variable is R b , the water bottom reflectivity coefficient. The frequency-domain transforms of the above summed and differenced signatures are each multiplied by the Backus operator (1+R b Z w ) 2 after initializing R b and the products are iteratively cross-correlated until the correlation function converges to a minimum. R b is perturbed after each iteration. The value of R b upon convergence is the local water bottom reflectivity coefficient.

摘要： A method is disclosed for processing seismic survey data to generate an unaliased 3-D DMO operator using two dimensional sampling theory to the spatial traverse of the operator as well as to the temporal axis. First a continuous DMO operator is generated along the line segment (10) connecting a source (5) and a receiver (R) directed at an arbitrary azimuth relative to a biaxial output grid. The operator is discretized at spaced-apart sample points (such as 16,18,20,30) along the DMO aperture segment (10), the spacing (D) being equal to or less than the output grid dimensions (dx,dy). An exponentially tapered sinc filter function is applied to the samples which are then interpolated onto the output grid.

摘要： Seismic data from co-located sensors of different genera are formatted into common velocity-receiver gathers and common pressure receiver gathers. A first ratio between the velocity signature amplitudes and the pressure signature amplitudes is measured within a fixed analysis window (14). A second ratio is measured between the pressure and velocity signatures for a weighting-zone window (18) of limited extent. The first and second ratios are combined to form an equalization operator. The pressure and velocity signatures from within the weighting zone window (18) are combined in the presence of the equalization operator to define a transient-free time-scale datum.
