MITIGATION OF NOISE IN MARINE MULTICOMPONENT SEISMIC DATA THROUGH THE RELATIONSHIP BETWEEN WAVEFIELD COMPONENTS AT THE FREE SURFACE
摘要
<p>A method and apparatus implementing a technique for mitigating noise in seismic data are presented. The technique includes estimating a noise component in a set of multicomponent seismic data representing a recorded wavefield from the relationship at the free surface of an upgoing component and a downgoing component decomposed from the recorded wavefield; and removing the estimated noise component from the seismic data. The noise component can be estimated by decomposing a recorded wavefield into an upgoing component and a downgoing component and isolating a noise component in the recorded wavefield from the relationship of the decomposed upgoing and downgoing components at the free surface.</p>
