WebThe method has two advantages: (1) the wavelet derived from the seismic data, containing the complex information in the acquisition, has a higher accuracy than the simulated far-field wavelet, and (2) with a small angle of incidence, the near offset of the seismic data has little effect on the absorption of the Earth, so, the extracted wavelet is … http://www.mosrp.uh.edu/assets/docs/Amundsen-Zhou-2013.pdf
An Effective Ghost Removal Method for Marine Broadband …
WebA newly reprocessed seismic dataset sheds new light on the hydrocarbon potential of the Gippsland Basin in Australia. ... which compensates for the receiver ghost notch. This is illustrated in the P-Z deghosted shot Frequency vs individual channel plot (row C, computation window of pink rectangle). By contrast, the residual ghost notch ... WebAug 31, 2014 · Conventional towed-streamer acquisition systems also suffer from attenuation of frequencies because of the ghost-notch effect caused by the reflection of seismic wavefields from the sea surface a short distance above the streamers, which interferes with the useful seismic signal. flights from honolulu to tucson arizona
Variable source depth acquisition for (an overall) improved signal …
WebMar 31, 2024 · seismic data is the existence of ghost that affects the frequency bandwidth contained on the seismic data. Ghost alters bandwidth to bandlimited. To reduce ghost … WebMarine seismic data acquisition has conventionally been carried out with source arrays positioned at a single depth. The resulting source-ghost notch is often taken as the limit … WebThe ghost effect in marine seismic data causes low-frequency suppression and frequency notch, resulting in incomplete frequency information for seismic records, which poses challenges for high-resolution imaging. The deghosting effect depends on the approximation of the ghost delay operator. flights from hon to ogg
