Abstract:

The present invention incorporates the use of model-driven and data-driven methodologies to attenuate multiples in seismic data utilizing a prediction model which includes multiply-reflected, surface-related seismic waves. The present invention includes beam techniques and convolving a predicted multiples beam with a segment of a modeled pegleg beam to obtain a convolved multiples beam. The convolved multiples beam can then he deconvolved to attenuate the multiples that are present in the original input beam.

US Classification:

702 11, 367 73, 703 10

Abstract:

A method and system for target-oriented reverse time migration for prestack depth imaging. One embodiment of the present invention includes determining an acquisition area within an earth model and also determining a reference surface near a target in the subsurface region of interest. The embodiment includes exciting wavefields from the reference surface and propagating the excited wavefields through the earth model. The embodiment additionally includes recording the wavefields at receiver locations in the acquisition area and at the target and synthesizing wavefields along the reference surface to reconstruct Green's functions which relate the receiver locations in the acquisition area to the target. The embodiment includes utilizing the Green's functions and prestack seismic data to determine subsurface characteristics of the subsurface region.

US Classification:

702 14, 702 16, 702 17, 702181, 703 2, 367 38, 367 53

Abstract:

Beamed data can be obtained from shot gather data, and debeamed data can be obtained from beamed data. Shot gather data for a geophysical volume of interest in a first domain and/or beamed data in a third domain may be received. The first domain has a component relating to seismic wave propagation time and a spatial component relating to lateral spacing. The third domain has a component relating to local plane wave arrival time at a beam center surface location and a component relating to plane wave arrival directions. Data may be transformed between the first domain and a second domain. The second domain has a frequency component and a spatial component corresponding to the spatial component of the first domain. A forward or reverse transform may be applied to transform shot gather data in the first domain to/from beamed data in the third domain.

US Classification:

367 43, 367 38, 702 17

Abstract:

A system and computer-implemented method for accounting for temporal dispersion in low-order finite difference seismic wave propagation is disclosed. An embodiment of the method includes transforming a seismic dataset from time domain to frequency domain to obtain a frequency-domain seismic dataset, applying a frequency-domain time varying filter to the frequency-domain seismic dataset to obtain a filtered frequency-domain seismic dataset, and transforming the filtered frequency-domain seismic dataset from the frequency domain to the time domain to obtain a time-domain filtered seismic dataset. The frequency-domain time varying filter is based on the effective phase velocity inherent in a finite-difference solution to the wave equation. The frequency-domain time varying filter may be applied to a synthetic seismic dataset that was generated by low-order finite difference modeling. A different frequency-domain time varying filter may be applied to recorded seismic data prior to reverse time migration.

Abstract:

Methods and apparatus are provided for delivering a plurality of video on demand (VOD) streams to customers. Video streams are received from a VOD server. The received streams are statistically multiplexed to transrate them and to optimize their video bandwidth. The statistically multiplexed streams are modulated, and then delivered to customers as single program transport streams.
