Deterministic Cancellation Of Air-Coupled Noise Produced By Surface Seimic Sources

View page
US Patent:
6381544, Apr 30, 2002
Filed:
Jul 19, 2000
Appl. No.:
09/619326
Inventors:
John J. Sallas - Plano TX
Rainer Moerig - Houston TX
Assignee:
WesternGeco, L.L.C. - Houston TX
International Classification:
G01V 128
US Classification:
702 17
Abstract:
A speaker system is used in conjunction with a surface seismic source that may be vibratory or impulsive. A speaker system having one or more speakers produces a sound signal that propagates primarily through the air and is received by microphones near the seismic spread. A transfer function between the microphones and the geophones in the seismic spread is determined from the speaker signal and used to filter out the airborne noise produced by the surface seismic source. The source may include or more vibrators that may be operated in a predetermined phase-relationship. The noise-attenuated signals may then be processed to separate out the contributions of the individual sources. Another embodiment of the invention uses accelerometer measurements of the reaction mass or the base plate of the vibrators or combination of the two measurements to invert the noise-attenuated signals.

Efficient Seismic Data Acquisition With Source Separation

US Patent:
7859945, Dec 28, 2010
Filed:
Jul 6, 2007
Appl. No.:
11/774055
Inventors:
John James Sallas - Plano TX, US
John B. Gibson - Arlington TX, US
Assignee:
CGGVeritas Services Inc. - Houston TX
International Classification:
G01V 1/04
US Classification:
367190, 367189
Abstract:
A method for the simultaneous operation of multiple seismic vibrators using unique modified pseudorandom sweeps and recovery of the transmission path response from each vibrator is disclosed. The vibrator sweeps are derived from pseudorandom binary sequences modified to be weakly correlated over a time window of interest, spectrally shaped and amplitude level compressed. Cross-correlation with each pilot signal is used to perform an initial separation of the composite received signal data set. Recordings of the motion of each vibrator are also cross-correlated with each pilot, windowed, and transformed to form a source cross-spectral density matrix in the frequency domain useful for source signature removal and for additional crosstalk-suppression between the separated records. After source signature removal in the frequency domain an inverse transform is applied to produce an estimate of each source-to-receiver earth response in the time domain. The method has application to both land and marine geophysical exploration.

System And Method For Determining A Frequency Sweep For Seismic Analysis

View page
US Patent:
8274862, Sep 25, 2012
Filed:
Oct 9, 2009
Appl. No.:
12/576804
Inventors:
John J. Sallas - Plano TX, US
Assignee:
CGG Veritas - Houston TX
International Classification:
G01V 1/38
US Classification:
367189
Abstract:
A sweep generator is employed to generate a sweep to be used by a seismic vibrator device for generating a desired target output spectrum, wherein the frequency sweep is designed so as to comply with one or more constraints imposed by the seismic vibrator device and/or imposed by the environment in which the device is to be used. In one embodiment, a sweep generator determines a sweep for achieving a desired target output spectrum by a given seismic vibrator device in compliance with at least a pump flow constraint imposed by the seismic vibrator device. In another embodiment, a sweep generator determines a sweep for achieving a desired target output spectrum by a given seismic vibrator device in compliance with all of multiple operational constraints of the seismic vibrator device, such as both mass displacement and pump flow constraints. Environmental constraints may also be accounted for in certain embodiments.

Appl. No.:
13/677661
Inventors:
John Sallas - Plano TX, US
Robert Dowle - Massy, FR
Laurent Ruet - Massy, FR
Benoit Teyssandier - Massy, FR
Assignee:
CGGVeritas Services SA - Massy Cedex
International Classification:
G01V 1/38
G01V 1/00
US Classification:
367 23
Abstract:
Method for generating an excitation signal for a first vibratory seismic source so that the first vibratory seismic source is driven with no listening time. The method includes a step of determining a first target spectrum for the first vibratory seismic source; a step of setting a first group of constraints for the first vibratory seismic source; and a step of generating a first excitation signal for the first vibratory seismic source based on the first group of constraints and the first target spectrum. The first seismic traces recorded with plural receivers can be identified when the first vibratory seismic source is driven with no listening time, based on the first excitation signal.

US Patent:
20130163381, Jun 27, 2013
Filed:
Dec 27, 2011
Appl. No.:
13/337396
Inventors:
John J. SALLAS - Plano TX, US
Assignee:
CGGVERITAS SERVICES SA - Massy Cedex
International Classification:
G01V 1/36
US Classification:
367 41
Abstract:
A method for seismic prospecting that includes a step of deploying plural vibratory sources on the ground; a step of receiving at each vibratory source a corresponding pilot signal for driving the vibratory source; a step of asynchronously actuating the vibratory sources to generate seismic waves into the ground; and a step of continuously recording seismic signals produced by the seismic waves. Pilot signals for the plural vibratory sources are obtained by spectrally shaping starting sequences into continuous pseudorandom sequences that are weakly correlated over a predetermined time interval.
