Technical Abstract

Far-field Source Signature Reconstruction Using Direct Arrival Data

Back to Technical Content
A precise knowledge of the seismic source far-field signature is required for accurate source de-signature. Near-field hydrophone data can be used to provide good quality signatures but are not always available. We describe a method of extracting the far-field signature from inversion of direct arrivals in the seismic data. We present the application of the methodology to a deep water survey offshore Gabon. The method can be applied to legacy surveys where near-field hydrophone data is unavailable for a more broadband result.
