    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: Methods and systems of analyzing and optimizing a seismic survey design are described. A system includes a plurality of seismic receivers disposed in a survey area at a plurality of receiver locations. The system also includes a plurality of seismic sources disposed in the survey area at a plurality of source locations. The plurality of receiver locations and the plurality of source locations are specified by a seismic survey design minimizing any artifacts identified in a filtered spectrum obtained by applying a frequency-wavenumber filter to a central midpoint space summation. The plurality of receiver locations and the plurality of source locations are determined based on a comparison of the filtered spectrum to a second filtered spectrum. The second filtered spectrum is for a second central midpoint space summation.

    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.

    Abstract: An apparatus for correcting for deviation of an ambient magnetic field direction from a reference direction in a marine environment includes: an instrument assembly vessel configured to move through the marine environment; an inertial reference direction device disposed on the instrument assembly vessel and configured to measure a deviation of an aiming direction of the instrument assembly vessel from the reference direction; a reference magnetic compass disposed on the instrument assembly vessel and configured to measure a direction of the ambient magnetic field direction with respect to the aiming direction of the instrument assembly vessel and to transmit the measured direction; and a processor configured to receive the measured deviation and the measured direction and to calculate the deviation of the ambient magnetic field direction from the reference direction using the received measured deviation and direction.

    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: The invention is an electric sweep type seismic vibrator source of the type used in seismic prospecting for hydrocarbons. The source uses an engine and generator combination to create electric power for all systems on the source such as driving a frame of linear electric motors that direct a rod or piston to contact the ground in a recurring fashion along with driving the source from location to location through a survey area. Preferably, a foot is arranged on the bottom end of the rod or piston for contact with the ground and by engaging the grid of motors to push down against the ground in a rapid progression, acoustic energy is created and delivered into the ground for geophones to sense and record.
