Pressure wave‐field deghosting for non‐horizontal streamers

Abstract

This abstract discusses a receiver deghosting method for seismic pressure wave‐fields that have been recorded at arbitrary depth. For horizontal streamers, the deghosted pressure wave‐field can be directly constructed from the scattered pressure wave‐field in the spectral domain. For non‐horizontal streamers, a system of equations is solved using a preconditioned conjugate gradient method. The mathematical derivation of the method is shown, and implementation issues are discussed. The effectiveness of the method is demonstrated using two synthetic examples.
