  • Patent number: 9348050
    Abstract: A seismic data processing method for predicting and removing unwanted near-surface noise, e.g. refracted waves and surface waves, from composite seismograms acquired with multiple, encoded seismic sources in which the time records from the different sources overlap or interfere. Surface-consistent properties are determined (403) for the near-surface noise and used to predict the noise waveforms (404) for the composite simultaneous-source seismograms, and the waveforms are then subtracted or adaptively subtracted (406) from the seismograms.

  • Patent number: 9291727
    Abstract: The invention relates to acquiring seismic data from the earth using geophones that are tuned to have differing frequency sensitivity ranges. The differing frequency sensitivity ranges cover a broader effective frequency range so that low frequency energy and high frequency energy are less attenuated in the raw data record. Two separate geophones would be used at the same node and three or more geophones may be used in combination at each node. When three or more geophones are used in combination, each may have a separate but overlapping frequency sensitivity range or two or more of the geophones may have the same frequency range sensitivity.
