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 wavefield 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. |
