Continuous Wavefields Method – The Acoustic Wavefield Generated by the Seismic Vessel
Autor: S. Hegna
Publikováno v: 82nd EAGE Annual Conference & Exhibition.
Summary The acoustic wavefield originating from the seismic vessel itself is generally not treated as acoustic signals in the imaging of marine seismic data, and is typically categorized as ambient noise. If this acoustic wavefield could be character

Results From a Shallow Water Field Test of the Continuous Wavefields Method
Autor: S. Hegna, T. Klüver, J. Lima
Publikováno v: Second EAGE Marine Acquisition Workshop.
Summary In autumn 2019, PGS acquired a 2D test in shallow water using the continuous wavefields method with the primary purpose of validating the method for shallow water environments. Various source configurations were tested, including different ti

Continuous Wavefields Method - Results from a Shallow Water Field Test
Autor: T. Klüver, S. Hegna, J. Lima
Publikováno v: EAGE 2020 Annual Conference & Exhibition Online.
Summary In the autumn of 2019, PGS acquired a small 2D test offshore Malaysia in water depths ranging mainly between 125 and 200m. The primary purpose of this test was to demonstrate the continuous wavefields method in shallow water areas. In additio

Methodology Utilizing Continuous Source and Receiver Wavefields - Signal to Noise Ratio Considerations
Autor: S. Hegna, T. Klüver, J. Lima
Publikováno v: 81st EAGE Conference and Exhibition 2019.
Summary The peak sound pressure levels (SPL) and the sound exposure levels (SEL) are significantly reduced with the seismic methodology based on the emission and recording of continuous source and receiver wavefields. The peak sound pressure levels a
