Abstract: A method of determining an optimal flare spacing for streamers towed behind a seismic vessel comprising the steps of: using a computer specially adapted with a seismic data analysis package to analyze prior seismic data for a survey area; analyzing migration broadcast patterns to estimate a maximum sampling distance; calculating a wavelet expansion as a function of flare spacing; creating synthetic gaps in the prior seismic data coverage by dropping traces at different flare spacing; testing capability of different interpolation algorithms in the seismic data analysis package to close the synthetic gaps; and determining an optimal flare spacing based upon the capability of the different interpolation algorithms to close the synthetic gaps.

Abstract: A method of measuring seismic signals generated by marine acoustic sources includes deploying at least one seismic sensor unit to a location on a floor of a body of water within a survey area, and recording seismic signals that include a real measured far field signature generated by a seismic source during a marine seismic survey. The method further includes automatically actuating a retrieval device to cause the at least one seismic sensor unit to rise to the surface, in response to expiration of the selected time period or an actuation signal from the surface, retrieving the at least one seismic sensor unit from the surface, and processing seismic data collected from the return signal. Processing including identifying a far field signature of the seismic source based on the signals detected by the seismic sensor, and designaturing the seismic data based on the far field signature.

Abstract: A method of processing seismic survey data includes: receiving seismic signatures emitted from a plurality of seismic sources during a frequency sweep as the sources are moved over a shot point; receiving a seismic trace generated by a seismic receiver, the seismic trace representing seismic signals resulting at least in part from the seismic signatures reflecting from an earth formation; performing an inversion of the seismic trace with the seismic signatures to separate the seismic trace into individual seismic signals, each of the individual seismic signals associated with a respective seismic source, wherein the inversion includes transforming the seismic trace to a frequency domain and generating frequency domain signals for multiple frequency bands in the frequency sweep; and during the inversion, applying a receiver motion correction to the frequency domain signals, and applying a Doppler correction to the frequency domain signals to correct for Doppler effects due to source motion.

Abstract: Methods of analyzing and optimizing a seismic survey design are described. Specifically, the sampling quality is analyzed as opposed to the overall quality of the whole survey. This allows for analysis of the impact of the offsets, obstacles, and other aspects of the survey on the sampling quality, which will improve the ability to compress the resulting data and minimize acquisition footprints.

Abstract: The presently disclosed technology relates to an arrangement for seismic acquisition where the spacing between adjacent pairs of receiver and sources lines is not all the same. Some receiver and/or source lines and/or receiver and/or source spacings are larger and some are smaller to provide a higher quality wavefield reconstruction when covering a larger total area or for a similar total area of seismic data acquisition, while providing a wavefield that is optimally sampled by the receivers and sources so that the wavefield reconstruction is suitable for subsurface imaging needs.

Abstract: A method for 2D seismic data acquisition includes determining source-point seismic survey positions for a combined deep profile seismic data acquisition with a shallow profile seismic data acquisition wherein the source-point positions are based on non-uniform optimal sampling. A seismic data set is acquired with a first set of air-guns optimized for a deep-data seismic profile and the data set is acquired with a second set of air-guns optimized for a shallow-data seismic profile. The data are de-blended to obtain a deep 2D seismic dataset and a shallow 2D seismic dataset.

Abstract: A method of performing notch compensation and a system to perform notch compensation for a first seismic streamer are described. The method includes disposing the first seismic streamer at a first depth, where the seismic streamer includes a first set of sensors to receive reflections resulting from a seismic source, the reflections indicating a notch at a frequency. The method also includes disposing a second seismic streamer at a second depth, the second depth being less than the first depth and the second seismic streamer including a second set of sensors to receive reflections resulting from the seismic source. The method further includes processing the reflections received by the first set of sensors and the second set of sensors together to derive the match filter, and applying the match filter to the reflections received by the first set of sensors of the first seismic streamer to compensate for the notch.
