f A New Method of Marine Seismic Source Signature Estimation from Near Field Measurements

One of the most important new seismic tools currently used in the E&P industry is the Time-lapse 3D seismic reservoir monitoring technology sometimes referred to as 4D seismic. However, it is only recently that geoscientists in the E&P industry have become aware of its limitations. One of the problems associated with acquisition is the seismic source consistency. The solution to this problem for the case of marine seismic sources can be easily achieved by monitoring each air-gun forming the marine seismic source.
