摘要： Computing device and method for determining primary and ghost components from recorded P-waves. The method includes receiving seismic data ( R , V ) with regard to the P-waves, wherein the seismic data includes vertical and radial components recorded with a buried two-component receiver (406); calculating with a processor (1002) a primary component ( P ) and a ghost component ( G ) from the vertical and radial components; and computing an image of a subsurface based on the primary and ghost components ( P , G ). The P-waves form a plane wave.

摘要： A technique includes receiving seismic data acquired by seismic sensors; and processing the seismic data on a machine to deghost the data. The processing includes deghosting the seismic data using a first deghosting technique that relies on a ghost model; deghosting the seismic data using a second deghosting technique that is independent from any modeling of the ghost; and selectively combining the results of the deghosting using the first and second deghosting techniques.

摘要： A method for estimating internal multiples in seismic data. The method includes selecting a subset from a set of regularly sampled seismic data based on a low-discrepancy point set. The method may then include integrating one or more depth integrals of the inverse-scattering internal multiple prediction (ISIMP) algorithm over each data point in the subset. After integrating the depth integrals, the method may then include integrating a function of the integrated depth integrals using a quasi-Monte Carlo (QMC) integration over the subset, thereby generating an estimate of the internal multiples.

摘要： An article comprising a computer accessible storage medium storing instructions that when executed by a processor-based system cause the processor-based system to: access data indicative of a particle motion measurement and a pressure measurement acquired by seismic sensors while in tow; and process the data to remove vibration noise from the measurements, the processing of the data including scaling the measurements relative to each other and subtracting one of the measurements from the other measurement.
The processor-based system implements a technique includes obtaining a particle motion measurement and a pressure gradient measurement, which were acquired by seismic sensors while in tow. The technique includes removing noise from one of the measurements, which includes scaling the measurements relative to each other and subtracting one of the measurements from the other measurement.
