MARINE DETERMINISTIC NOTCH COMPENSATION

摘要

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.

1. A method of performing notch compensation for a first seismic streamer, the method comprising:
disposing the first seismic streamer at a first depth, the seismic streamer comprising a first set of sensors configured to receive reflections resulting from a seismic source, the reflections received by the first set of sensors indicating a notch at a frequency; disposing a second seismic streamer at a second depth, the second depth being less than the first depth and the second seismic streamer comprising a second set of sensors configured to receive reflections resulting from the seismic source; 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.
